The Weekly Challenge

HEADLINES

Welcome to the Week #253 of The Weekly Challenge.

E. Choroba usually shares solutions in Perl but last week he shared solutions in C++ as well.

Joao Felipe shared solutions in Uiua.

While I am talking about guest contributions, there is one contributor, Eric Cheung, who regularly contributes solutions in Python on day one itself.

It feels nice to see so many Perl and Raku experts trying other programming languages too. I still remember it all started with Python and now we have solutions in 100+ different programming languages.

Last 5 weeks mainstream contribution stats. Thank you Team PWC for your support and encouragements.

Task 1: Split Strings

Submitted by: Mohammad S Anwar

You are given an array of strings and a character separator.

Write a script to return all words separated by the given character excluding empty string.

Example 1

Input: @words = ("one.two.three","four.five","six")
       $separator = "."
Output: "one","two","three","four","five","six"

Example 2

Input: @words = ("$perl$$", "$$raku$")
       $separator = "$"
Output: "perl","raku"

Task 2: Weakest Row

Submitted by: Mohammad S Anwar

You are given an m x n binary matrix i.e. only 0 and 1 where 1 always appear before 0.

A row i is weaker than a row j if one of the following is true:

a) The number of 1s in row i is less than the number of 1s in row j.
b) Both rows have the same number of 1 and i < j.

Write a script to return the order of rows from weakest to strongest.

Example 1

Input: $matrix = [
                   [1, 1, 0, 0, 0],
                   [1, 1, 1, 1, 0],
                   [1, 0, 0, 0, 0],
                   [1, 1, 0, 0, 0],
                   [1, 1, 1, 1, 1]
                 ]
Output: (2, 0, 3, 1, 4)

The number of 1s in each row is:
- Row 0: 2
- Row 1: 4
- Row 2: 1
- Row 3: 2
- Row 4: 5

Example 2

Input: $matrix = [
                   [1, 0, 0, 0],
                   [1, 1, 1, 1],
                   [1, 0, 0, 0],
                   [1, 0, 0, 0]
                 ]
Output: (0, 2, 3, 1)

The number of 1s in each row is:
- Row 0: 1
- Row 1: 4
- Row 2: 1
- Row 3: 1

Last date to submit the solution 23:59 (UK Time) Sunday 28th January 2024.
