The Weekly Challenge

HEADLINES

Welcome to the Week #322 of The Weekly Challenge.

For the last two weeks, I keep forgetting to mention Andrew Shitov, who is back in action. We have had solutions to Week #320 and Week #321 in Raku so far.

Welcome back, Andrew, it’s always a pleasure to have you back. Thank you for your support and contributions.

I would also like to mention, Luca Ferrari, for getting back to his full capacity. For sometime, he only shared Raku solutions where he used to have mix of all. I noticed he is back with his magic once again. So, thank you for your contributions.

Similarly, Simon Green, once again started sharing solutions in Perl as well. I know his first choice is always, Python. And I must admit, he never disappoints me. Thank you for keeping the spirit high.

With so much happening, we matched the best week contributions of the year 2025. It was the Week #312 when we had 95 contributions. It was so close to the target.

Keep sharing the knowledge as always.

Well done, Team PWC, and thank you.

Task 1: String Format

Submitted by: Mohammad Sajid Anwar

You are given a string and a positive integer.

Write a script to format the string, removing any dashes, in groups of size given by the integer. The first group can be smaller than the integer but should have at least one character. Groups should be separated by dashes.

Example 1

Input: $str = "ABC-D-E-F", $i = 3
Output: "ABC-DEF"

Example 2

Input: $str = "A-BC-D-E", $i = 2
Output: "A-BC-DE"

Example 3

Input: $str = "-A-B-CD-E", $i = 4
Output: "A-BCDE"

Task 2: Rank Array

Submitted by: Mohammad Sajid Anwar

You are given an array of integers.

Write a script to return an array of the ranks of each element: the lowest value has rank 1, next lowest rank 2, etc. If two elements are the same then they share the same rank.

Example 1

Input: @ints = (55, 22, 44, 33)
Output: (4, 1, 3, 2)

Example 2

Input: @ints = (10, 10, 10)
Output: (1, 1, 1)

Example 3

Input: @ints = (5, 1, 1, 4, 3)
Output: (4, 1, 1, 3, 2)

Last date to submit the solution 23:59 (UK Time) Sunday 25th May 2025.
