HEADLINES

Welcome to the Week #296 of The Weekly Challenge.

Welcome back, Luca Ferrari and thanks for sharing solutions in Raku, Python, Java and PostgreSQL.

Over the last couple of weeks, I’ve noticed a slightly slower pace of participation. Could it be that the holiday season has already kicked in? That said, there are still plenty of contributions in various languages. On top of that, we’ve received some very technical blog posts from the usual suspects. Well done team, keep sharing your knowledge and experiences with us!

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

Task 1: String Compression

Submitted by: Mohammad Sajid Anwar

You are given a string of alphabetic characters, $chars.

Write a script to compress the string with run-length encoding, as shown in the examples.

A compressed unit can be either a single character or a count followed by a character.

BONUS: Write a decompression function.

Example 1

Input: $chars = "abbc"
Output: "a2bc"

Example 2

Input: $chars = "aaabccc"
Output: "3ab3c"

Example 3

Input: $chars = "abcc"
Output: "ab2c"

Task 2: Matchstick Square

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to find if it is possible to make one square using the sticks as in the given array @ints where $ints[ì] is the length of ith stick.

Example 1

Input: @ints = (1, 2, 2, 2, 1)
Output: true

Top: $ints[1] = 2
Bottom: $ints[2] = 2
Left: $ints[3] = 2
Right: $ints[0] and $ints[4] = 2

Example 2

Input: @ints = (2, 2, 2, 4)
Output: false

Example 3

Input: @ints = (2, 2, 2, 2, 4)
Output: false

Example 4

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