HEADLINE The week #075 tasks turned out to be a lot trickier than expected. Generally Task #1 is meant for beginners only but this time it was not the case. It wasn’t my plan when I proposed the task. I thought couple of for-loops and job done. But when I actually started working on the task, I realised it wasn’t as simple as I thought initially. But the good thing is, I got to know about Dynamic Programming (DP).

BLOG: The Weekly Challenge #072

HEADLINE No Linked List related task this week? I am glad, this week focus was more Array/List related. Technical speaking Array and List aren’t the same in Perl. I must admit until I read the article by brian d foy, I thought they were the same. As the famous saying, you learn something new every day. Both the tasks, this week were not terribly difficult. I noticed many members of Team PWC attempted other languages because they finished the tasks in no time.

Perl Weekly Challenge - 072

HEADLINES Today is the first Monday of the August 2020 and it is time to announce the Champion of the Month.

It shows the dedication that he has towards the weekly challenge. Thanks Jaldhar for your support and encouragement. I am not sure, if you have read the blog by Dave Jacoby where he mentioned the comment by Walt Mankowski where he encouraged Dave to do the Trim Linked List as a Singly Linked List purely.

BLOG: The Weekly Challenge #071

HEADLINE With another Linked List related task, I am now enjoying it a lot. It also gives me the opportunity to work with Class in Raku. Learning Raku has changed my thinking a big way. The developer inside me is more organised than before. Also doing regular weekly challenge made me think from unit test point of view every time I come up with a solution. In fact, it dictates the design of my solution.

HEADLINES Finally the wait is over, we found volunteer for Raku Reviews. Any guess? Andrew Shitov joined the team of Raku Reviewers. The best part is, he is doing Live Video Reviews, which is even more fun. I watched all his reviews so far, start to end. There are plenty to learn from just watching him review Raku solutions. He has already done for Week #066 and Week #069.

HEADLINE Before I talk about my contribution this week, I would like to talk about my encounter with Swift programming language recently. For the first time, I felt confident that I can share my Swift solution to the Character Swapping task of the Perl Weekly Challenge - 070. Why Task #1 only? Well, you guessed it correctly because it is meant for the beginners. With the submission of my first contribution in Guest Language, I now find myself in the Guest List as you must have seen in RECAPS every week.

Perl Weekly Challenge - 070

HEADLINES Colin Crain has been helping with Perl reviews since Week #065. I would like to thank him for all the hard work. I liked the new layout he came up for the last review. It is different from others. I am not sure about others but I always look forward to review every week. We are still looking for helping hands for Raku reviews. Please let us know perlweeklychallenge@yahoo.

RECAP - Perl Weekly Challenge - 069

HEADLINES Welcome back Rage311 after the break. I hope you stay longer this time. Walt Mankowski surprised me this week by sharing solutions in C and Python. Thanks to him, C is the new language introduced to us. I would also like to thank him for taking Python contributions closer to the magic number. Andrew Shitov joined the gang and shared his first C++. Apart from Andrew, we have few others contributors who also contributed in C++, i.

BLOG: The Weekly Challenge #069

HEADLINE The Task #1 of Perl Weekly Challenge - 069 raised a very interesting question i.e. is 1 strobogrammatic number? So far, I got mixed response some says yes and some not. My first thought was Yes, it is but later changed my mind. It is controversial and I don’t want loose the focus on the task itself. Please remember the objective is to have fun and not to get into controversial domain.

Perl Weekly Challenge - 069

HEADLINES With three members joining Team PWC, we now have 173 members. I welcome all of them with open arms. I would like to mention one member explicitly Myoungjin Jeon, why? He is someone who did Perl long time ago and currently a Chef by profession. What impressed me the most about him is that he never let his love for Perl die. I hope he finds the weekly challenge interesting to keep him going.

RECAP - Perl Weekly Challenge - 068

HEADLINES Two of the three members who joined the Team PWC last week, shared solutions to the “Perl Weekly Challenge - 068”. When I requested them for a brief introduction, most of them came back with Perl background. But then Myoungjin Jeon surprised me with solutions in Raku as well. I came across one of his blog where he mentioned about his work on creating combinations in Perl in the year 2013.

BLOG: The Weekly Challenge #068

HEADLINE The Week #068 is my 23rd week in a row participating the weekly challenge. For the first time, I created a package to deal with the “Reorder List” task. It really helped me in thinking straight when dealing with linked list. With the help my favourite CPAN module Moo, creating class is like piece of cake as shown below. package Node; use Moo; has v => (is => 'rw'); has c => (is => 'rw'); sub show_link { my ($self) = @_; my $head = $self; my @v = (); while ($head->c) { push @v, $head->v; $head = $head->c; } push @v, $head->v; return sprintf("%s", join ' -> ', @v); } I will talk more in detail later down below.

HEADLINE This week both tasks had one thing in common i.e. pairing two or more list. In the past, I have taken the help from CPAN module Algorithm::Combinatorics for such tasks. However this time, I wanted to get my hand dirty and came up with the following: # generate all possible combinations my @combinations = (''); foreach my $members (@data) { @combinations = map { my $member = $_; map $member.

BLOG: The Weekly Challenge #066

HEADLINE The much awaited event, **Conference in the Cloud” took most of my free time. Having said that I still managed to do Live Coding YouTube videosfor Divide Integers and Power Integers. I really enjoyed both tasks, specially Power Integers. It didn’t take long to solve both tasks. I was able to get it done by midweek. But for YouTube video, I had to wait until the conference was over. Thanks to the Chief Editor of Perl Weekly newletter editorial note, I now have 67 subscribers to my YouTube Channel.

Perl Weekly Challenge - 067

HEADLINES The highlight of last week was mostly the much awaited event “Conference in the Cloud”. I must admit, I enjoyed every bit. It was nice to see so many familiar names from Team PWC in the audience. Among many talks, I was really happy to watch Damian Conway live for the first time. Colin Crain final joined the team of reviewers and submitted first Perl Review. Please do share your comments and suggestions.

RECAP - Perl Weekly Challenge - 066

HEADLINES Welcome back Walt Mankowski and thanks for sharing your contributions. Also thanks for sharing Python solutions. Thanks Andrew Shitov solving past challenges and blogging about it as well. Python is the most popular language among the Team PWC after Perl and Raku. We now have 10 contributors for Python. 1) Lubos Kolouch: Python (25). 2) User Person: Python (21). 3) Orestis Zekai: Python (16). 4) Burkhard Nickels: Python (8).

Perl Weekly Challenge - 066

HEADLINES The week #065 started on a happy note when I received the contribution by Andrew Shitov. He doesn’t need an introduction, does he? He even blogged about his contribution. On a serious note, I got the sense that most of the Team PWC found the task Palindrome Partition very confusing. I must admit, I also realised when I solved the task myself. I noticed there are more solutions than what I thought initially.

RECAP - Perl Weekly Challenge - 065

HEADLINES I noticed Yet Ebreo catching up past challenges. In the series, he shared Week #062 and Week #063. It is always nice to see members taking interest in solving past challenges. I would like to encourage anyone who joined us recently, please do share your solutions to the past challenges. If you missed the deadline to submit your solutions, please do share anyway. And why not blog about it as well, if you haven’t done so before.

BLOG: The Weekly Challenge #065

HEADLINE Having missed the blog last week, I wanted to make sure it doesn’t happen again. I did catch up the last week blog this week. How did I get time this week around? Well, I delayed Live Coding session for Perl and Raku until Sunday. As of now, I have done 2 videos, one each for both tasks in Perl. I am planning to do one more later in the evening in Raku just for “Digits Sum” task.

BLOG: The Weekly Challenge #064

HEADLINE This weekly blog is coming a week later than normal. Why? Last week I tried Live Coding for the first time. It was scary but enjoyable experience. It took more time than the blog. Having said that I didn’t want to stop blogging about my solutions. So here you go, I am sharing my solutions with you. Just for record, please find below links to the Live Coding videos.

Perl Weekly Challenge - 065

HEADLINES Few days ago, Colin Crain, offered to do Perl review of the past challenges. A big THANK YOU from all of us. Soon we will have the fun of reading reviews. I am still looking for Raku, just a gentle reminder. It would be nice, if both kickstart together. I have been hooked into YouTube video of live coding by Richard Park. It was Richard who first started sharing his YouTube video of live coding.

RECAP - Perl Weekly Challenge - 064

HEADLINES Not sure about others but I have noticed E. Choroba is on a mission to improve his past solutions. Square with 5 distinct digits Invert Tree Find Numbers Nothing comes FREE, the above improvements is keeping E. Choroba too busy to do weekly blog. We are missing them very badly. Hopefully it will start again very soon. Do you remember, Jaldhar H. Vyas? He was missing from the scene for sometime but he is back in action now, back to back 2 weeks.

Perl Weekly Challenge - 064

HEADLINES Two recent tragedies really upset me the most, first the killing of George Floyd and second the killing of pregnant elephant in India. All Life Matters, including Black. I try to keep my political views to select few and avoid sharing on social media. I hope I am not crossing the lines here. The Week #062 was the dullest week ever earlier but thanks to all Team PWC members, it is no longer the least contributions week.

RECAP - Perl Weekly Challenge - 063

HEADLINES Welcome back Jaldhar H. Vyas, we missed you. For the first time ever, I noticed E. Choroba missed a week i.e #062. However, he made it up and shared the solution to the Sort Email Addresses. To my surprise, he even updated his solution to the task Longest Common Substring of Perl Weekly Challenge - 018. It shows his commitment to continuous improvement. Thanks to Richard Park contributions, the solutions in APL (18) is moving up in the rank #003, only behind Python (87) and C++ (22).

BLOG: The Weekly Challenge #063

HEADLINE After the most difficult week (Week #062), it was very satisfying. I found both the tasks this week (Week #063) fun and challenging. The best part was that I could do both tasks in an hour, which is rare. I liked the “Rotate String” task very much. Thanks to Ryan, we already had test cases handy for the “Last Word” task. I will talk about each in detail down below.

Perl Weekly Challenge - 063

HEADLINES Today is the first Monday of the June 2020 and you guessed it correctly. It is time to announce the Champion of the Month.

HEADLINE Once again, Neil Bowers, came up with another exciting task for all Team PWC members. Like always, it was fun task. Thanks to Ryan for providng sample data and expected result based on the definition of the task. Half the job done already. The only thing left for the us, is get on with the job. I noticed Raku needed slightly different approach then the Perl. It could be I am doing something very badly.

Perl Weekly Challenge - 062

HEADLINES Happy Idd to all Team PWC members. It was the first Idd celebration when we couldn’t go to the mosque for special prayer. Life is no longer same even after so many weeks on lockdown. It appears we have to start adjusting to the new rules. From next week, I will have new routine to follow as Ramadan is over. Working hours is going to be back to normal.

RECAP - Perl Weekly Challenge - 061

HEADLINES We all know, Perl Weekly Challenge, primarily focus on Perl and Raku. However, in recent weeks, I noticed Team PWC members actively sharing solutions in other guest languages. As of today, we have received solutions in 16 guest languages, Python being the most popular language. There is still scope for more guest languages. If you haven’t tried anything so far then why not give it a try. Newly joined member Sangeet Kar shared his first Python solutions.

BLOG: The Weekly Challenge #061

HEADLINE At first, I thought Product SubArray is easy task. Therefore I went public categorised as Task #1. My definition of easy task is you just start coding without doing any ground work. However when I started coding, I had to take a pause and do processing in my head befoore coding. So then as per my definition, Product SubArray no longer consider as an easy task. After finishing the task in no time once I understood the flow, it turned out to be clean solution.

Perl Weekly Challenge - 061

HEADLINES I never miss the opportunity of celebration, no matter how small the occassion is. My form of celebration is sharing the achievements with the community in general. If you remember, I wrote a blog when we completed 3 months of weekly challenge. Then again when we completed 6 months. So why no celebration at the end of first anniversary? Certainly it was the biggest moments for all of us associated with Perl Weekly Challenge or rather The Weekly Challenge.

RECAP - Perl Weekly Challenge - 060

HEADLINES Couple of months ago, on the request of one of the Team PWC member, Wanderdoc, we created Early Bird Club. So what is it all about? The club members get the first glimpse of upcoming challenges. How can anyone join the club? Just drop us a line with your intention to perlweeklychallenge@yahoo.com. I always try to give the club members full weekend i.e. Saturday and Sunday to play with the upcoming challenges before others get their hand the following Monday morning.

BLOG: The Weekly Challenge #060

HEADLINE I am not sure about you guys but I found writing blog is very nice feeling. I get nice ideas to clean up the code. This week, I even found a bug that even unit test couldn’t catch. I would rather not share it, quite embarassing. The bug was in my Perl solutions to the “Find Numbers” task. My git commit tree might disclose it, if you really want to know.

Perl Weekly Challenge - 060

HEADLINES Last week, we had the pleasure to interview our Champion of the Perl Weekly Challenge, Luca Ferrari. Please check out the full interview.

I would like to thank Team PWC member Richard Park for introducing the amazing language APL.

RECAP - Perl Weekly Challenge - 059

HEADLINES Last week, 3 new members joined the Team PWC, namely Max Kossek, Sangeet Kar and Shawak. We welcome all of them and hope they would have as much fun as we have had so far. I would like to mention one thing about Max Kossek, in his first week itself, he solved past four weeks solutions. Great attempt. Keep it up, Max. Another pleasant surprise from last week was, one of the earliest member of the team, Colin Crain started blogging about his work.

BLOG: The Weekly Challenge #059

HEADLINE This week, I changed the format of my weekly blog slightly. Why? Well, I wanted to keep the Perl and Raku solutions next to each other so that it is easier for reader (me, mostly) to see the difference. It gives me immense pleasure to see the end result when I am done translating Perl solutions into Raku. It looks lot cleaner and precise. The only thing it is behind is performance when I do comparison.

BLOG: The Weekly Challenge #058

HEADLINE This week, I struggled with both the task, to be honest. Dealing with alpha part of the version was really pain in the neck. Every time, I struggle with any task, I follow the college days course of action i.e. pick a pend and paper. I start dribbling the thought process, it really helps in getting the idea out on the paper. Once the rough draft is ready, it is time to face the unit test trial.

HEADLINE Of the two tasks, my favourite was Shortest Unique Prefix. I must confess I have never done this before. It was fun solving though. I enjoyed it thoroughly. As always, Raku solution looks more elegant, in my hunble opinion. With every passing week, I learn something new in Raku and get to practice what I learnt so far. The weekly challenge is giving me an opportunity to explore the nitty gritty of Raku.

Before I say anything about my contributions, I would like to share my sweet encounter with Raku. Last week while working on the task Flip Binary using Raku, I was struggling to figure out all the binary strings with maximum 1s. I had the results in a Hash where key was the binary string and value was the total count of 1s in it. The idea was to sort the Hash by values first then sort by keys.

For the first time, since I started participating the weekly challenges, I thought of doing one-liner. With handy CPAN modules, it was pretty straight forward in Perl. Even Raku with built-in features wasn’t far behind Perl. Like in the past, I learn something new in Raku every week. This week was no different. I will share what I learnt this time later.

Raku Solutions Weekly Review Task #1: Stepping Numbers Before going into the subject, I should apologize for having suspended my reviews of the Perl Weekly Challenge submissions for about two and a half months.

I noticed now a days, I go for solution with unit test. I will give the credit to fellow Team PWC member, E. Choroba. It feels great when you see the test pass at the end. Well the solution looks little different than just standalone solution. For that reason, I decided to do both for Raku solutions. Also this allowed me to explore unit testing in Raku.

Perl Weekly Challenge - Story so far ...

We are now 3 months old and growing fast every week with the support of wider Perl Community. The prime motto of the “Perl Weekly Challenge” is to promote Perl (be it Perl5 or Perl6). I was looking for fun way of doing it. Being, co-editor of Perl Weekly newsletter, I noticed that not many people blog about interesting use of the language. I must say, Perl6 community is doing far better than Perl5.

This week, Joelle Maslak sent us the first solution in Perl6 as Pull Request [#265]. Then came Scimon Proctor, again in Perl6 as Pull Request [#266]. Kevin Colyer submitted the next in Perl6 as Github gist. By now, I started thinking where are all #Perl5 hackers. I didn’t have to wait longer, Pete Houston sent us the solution in Perl5 by email. Finally we had our first complete solution in Perl5 by Dave Jacoby as Pull Request [#271].

Kian-Meng Ang Weekly Review: Challenge - 012

Continues from last week. For a quick overview, read through all questions and recap of the challenge first. This week was quite unique as we observed there were several submissions where submissions were based on existing solutions but were done in a more alternative and elegant way. Moreover, some of these show case the expressiveness of Perl programming language itself, which is also one of the key goal of this weekly challenge.

Perl Weekly Challenge - 013

Couple of weeks ago, I tweet below about a surprise for all registered members. It is now time to annouce the surprise. Few weeks ago, Peter Sergeant of PerlCareers contacted me by email and offered to sponsor the weekly challenge to make it more attractive. He offered the winner of weekly challenge $50 Amazon Voucher. We, Peter and I, worked out the formalities and other related issues. All registered members who contribute to the weekly challenge for the week will go into the ballot box.

RECAP - Perl Weekly Challenge - 012

I was little late in releasing the weekly challenge last time. If I remember correctly it was around 4am Monday morning. Still, by 9am (UK time), I had first solution as PR by none other than the Scimon Procotor himself. And within the next hour, he submitted the solution to the second challenge. By lunch time, I had one more member Ozzy submitted solution to the first challenge. This week, Joelle Maslak joined 100+ score club and became the second member.

Kian-Meng Ang Weekly Review: Challenge - 011

Continues from previous week. For a quick overview, read through all questions and recap of the challenge first. For those who are new to the weekly review post, the main purpose of weekly review is to document down interesting approaches of using Perl programming language to solve each week challenges. Code reading or review allows us to learn / relearn, discover / rediscover, and appreciate / reappreciate (some participants uses other programming languages in their day job) new, interesting, and quirky things accomplished with Perl (unfortunately Perl 5 for now).

Perl Weekly Challenge - 012

With every week, the team is growing and participation is also growing. I also love the fact that members even taking on optional API challenge regularly now. I hope, you are having fun solving weekly challenges as much as I am. RECAP Here is the recap of last week challenge. CHART Please take a look at the charts showing interesting data. I would like to thank everyone for their valuable suggestions.

RECAP - Perl Weekly Challenge - 011

I noticed members taking on the optional API challenge more regularly. Before only handfull members bother taking the challenge. I am also happy to see familiar faces coming back to the weekly challenge after short break. I hope they continue with it and enlighten us. Adam Russell Adam solved the Fahrenheit-Celcius challenge in such a way that even a kid would follow it without any explanation. Simply Cool. He treated the second challenge of Identity Matrix in the similar fashion.

Kian-Meng Ang Weekly Review: Challenge - 010

Continues from previous week. For a quick overview, read through the questions and recap of the challenge. Challenge #1 The Wikipage page have a good introduction and manual calculation of conversion of Arabic numerals to Roman numerals. Read Laurent Rosenfeld’s blog post for the finer implementation details. Most participants uses a hash to map between Arabic and Roman numerals. Since order of the matching roman numerals against the Arabic values is important, we’ll need to sort it before any conversion.

Perl Weekly Challenge - 011

I noticed regular flow of new members to the team of Perl Weekly Challenge. Some of them quite actively take part in the challenge as well as blog about it. Some while on vacation, didn’t miss to take on weekly challenge. I remember, one member, submit the solution from her sickbed. I am gratefull to each of them for their support. I am equally thankfull to those who take time and blog about their solution.

I came to know about one secret player of Perl Weekly Challenge just few days ago. Any guesses? He is the Damian Conway. He doesn’t need any introduction. My first encounter with him was when I bought his book Perl Best Practices. I have been a big fan of him since then. Checkout his blog. I would also like to mention another newly joined member Yozen Hernandez. He blogged first time ever that too about his solution to the Perl Weekly Challenge.

RECAP - Perl Weekly Challenge - 009

I would like to this opportunity to thank one of the respected member Kian-Meng Ang for the help in reviewing Perl 5 challenges every week. Checkout her last review if you haven’t seen already. Ever since I started reviewing the challenges, I am looking for volunteer to do the same for Perl 6. I know it is weekly commitment and can be tiresome. If we can create team of reviewers for each languages then it would be even more fun.

The Challenge - 008 participation was same as the Challenge - 007 in terms of number of members participated. However this time we received more than solution with the introduction of the optional third API challenge. As a matter of fact, Joelle Maslak care to answer the third challenge. She solved the third challenge in Perl5 and Perl6. Adam Russell Adam making good use of unpack() to solve the perfect numbers challenge.

Weekly Review: Perl Weekly Challenge - 007

Below is the write-up review (only covers Perl 5) of the Perl Weekly Challenge #007 of all the submitted answers. You can read the original questions first to understand the details of these two challenges. Challenge #1 If we read the question carefully, there are several steps to solve this problem. First, to find all niven number from 0 to 50 inclusively. Second, to find the sum of its digits of this range of number.

Last week was not very active in terms of number of participations. Having said that the quality of the solutions is always on the top. Some went for the kill, you can’t afford to miss it. Enjoy the code. Adam Russell Adam got the help from CPAN module Data::Dump and the end result is unbelievable simple. Check out his code. Alicia Bielsa Alicia submitted the solution to the first question.

Perl Weekly Challenge - 006

Perl Weekly Challenge introduced me to so many genious around the globe. It would be unfair to name a few. You know who I am talking about. The main objective of the project was to introduce Perl to more people and allow sharing the magic of Perl. In the last 5 weeks, I can say that I have personally learnt a lot from many greats. RECAP Here is the recap of last week challenge.

RECAP - Perl Weekly Challenge - 005

I would like to talk about blog written by some members this week. In the past, I went into the details of Perl 5 solutions mainly. Lets change the trend this time. Following blogs have been reported last week. Each blog is a text book in itself as it teaches you so many things. I enjoyed reading each and every blog. Please do read them when you get time. Adam Russell https://adamcrussell.

Perl Weekly Challenge - 005

The best part of the Perl Weekly Challenge is reading the blog by the members. Personally, I like the journey of an idea to final solution. If you look at closely all the blogs, every member has unique style. They all think differently but ends up with the same result. I have become fan of few in the last few weeks. Don’t get me wrong, reading code is fascinating but boring.

RECAP - Perl Weekly Challenge - 004

For the first time ever, I published RECAP blog before the weekly challenge. It is the sign that things are settling down. Members are using Pull Request more frequently to submit the solutions. Last Sunday, when I made the Challenge 004 public, I couple of people responded in no time. The first person was Kivanc Yazan and he announced it on Twitter. The next person followed him was @smokemachine. He has been regular since last week.

Perl Weekly Challenge - 004

I noticed last week, less participation than the previous week. Why? Honestly speaking I have no clue. Could it be the questions were too tricky for the challenge? The week before, I received the feedback that the questions were too easy and simple. So I went for little trickier one this time. It seems that I have to balance it somehow. I am gratefull to all members submitting the solutions as Pull Request.

RECAP - Perl Weekly Challenge - 003

Every week, I release the challenge by email first and then on Twitter. I wait for about 30 minutes to get the first response to the challenge. I also look at the Google Analytics Realtime Chart to see how many users are reading the new challenge page and from which part of the world. Last week, I didn’t have to wait long, I saw the first reaction on Twitter from Khalid.

Proposed Solution for Challenge - 002

As received in response to the challenge by Philippe Bruhat. Highly recommended. Write a script or one-liner to remove leading zeros from positive numbers. As a filter: perl -ple 's/^0+//' Challenge #2 Write a script that can convert numbers to and from a base35 representation, using the characters 0-9 and A-Y. Those who remember The Perl Review Code golf contest may remember this challenge. In February 2002, brian d foy wanted to try his hand at publishing a Perl magazine (following the demise of The Perl Journal).

RECAP - Perl Weekly Challenge - 002

I noticed the timing of releasing the weekly challenge is not helping anyone in UK timezone as I released around mid-night. So if somebody who lives in other side where it is day they get to try the challenge first. I realised within few hours of making the challenge public, I starts getting feedback but none from UK member. It is only when it is Monday morning, I see reactions from them.

Perl Weekly Challenge - 003

Last week challenge turned out to be a cakewalk for Perl 6 hackers. This shows my lack of knowledge of Perl 6. I have requested our inhouse Perl 6 experts to share some challenging questions. I already received few and kept in the challenge bank. I will use it in the coming weeks. Credit will be given to the hacker when published. We highly recommend that you submit you solutions as PR to the repository.

RECAP - Perl Weekly Challenge - 001

Welcome to the first weekly recap of “Perl Weekly Challenge”. Apology for the delay, I was supposed to release this blog with the second challenge of the series.
