Check out current team members.



Task #1



Create a script to demonstrate Ackermann function. The Ackermann function is defined as below, m and n are positive number:

  A(m, n) = n + 1                  if m = 0
  A(m, n) = A(m - 1, 1)            if m > 0 and n = 0
  A(m, n) = A(m - 1, A(m, n - 1))  if m > 0 and n > 0

Example expansions as shown in wiki page.

 A(1, 2) = A(0, A(1, 1))
         = A(0, A(0, A(1, 0)))
         = A(0, A(0, A(0, 1)))
         = A(0, A(0, 2))
         = A(0, 3)
         = 4


Task #2



Create a script to parse URL and print the components of URL. According to Wiki page, the URL syntax is as below:

scheme:[//[userinfo@]host[:port]]path[?query][#fragment]

For example: jdbc://user:password@localhost:3306/pwc?profile=true#h1

  scheme:   jdbc
  userinfo: user:password
  host:     localhost
  port:     3306
  path:     /pwc
  query:    profile=true
  fragment: h1


Task #3

Last date to submit the solution 23:59 (UK Time) Sunday 21st July 2019.
