Perl Weekly Challenge - 045

Wednesday, Jan 29, 2020| Tags: Perl, Raku


HEADLINES



Last week had been the toughest week for me. My dad is now back home and doing well. Thanks each and every person for the best wishes. I know everything is messed up at the moment. I came back from India with throat infection and really bad cough. I am not fully recovered yet but still improving day-by-day. I would like to thank Ryan Thompson for doing Perl Review in my absence. There is going to be a short pause on Raku review, please bear with us, unless someone from the team volunteer to take this challenge for a short period.

Last but not the least, we woud like to thank each and every member for their support and encouragement.

GUESTS



Darren Bottin shared solution to Task #1 Prolog.

Please find out past solutions by respected guests. Please do share your creative solutions in other languages.



TASK #1



Square Secret Code

The square secret code mechanism first removes any space from the original message. Then it lays down the message in a row of 8 columns. The coded message is then obtained by reading down the columns going left to right.

For example, the message is “The quick brown fox jumps over the lazy dog”.

Then the message would be laid out as below:

thequick
brownfox
jumpsove
rthelazy
dog

The code message would be as below:

tbjrd hruto eomhg qwpe unsl ifoa covz kxey

Write a script that accepts a message from command line and prints the equivalent coded message.



TASK #2



Source Dumper

Write a script that dumps its own source code. For example, say, the script name is ch-2.pl then the following command should returns nothing.

$ perl ch-2.pl | diff - ch-2.pl


Last date to submit the solution 23:59 (UK Time) Sunday 2nd February 2020.
