The Weekly Challenge

HEADLINES

Welcome to the Week #293 of The Weekly Challenge.

It was a bit rough week for me as I am trying to get back to my usual routine. Also I was a bit busy with London Perl Workshop 2024. I was pleasantly surprised to meet fellow team member, Arne Sommer, after a long time. Last time we met was at conference in Riga many years ago. I noticed another name, Santiago Leyva in the list but didn’t get to say hi unfortunately. If anyone interested in my talk then you can grab the slides as pdf.

Please keep sharing the knowledge every week and don’t forget to have fun too.

Task 1: Similar Dominos

Submitted by: Mohammad Sajid Anwar

You are given a list of dominos, @dominos.

Write a script to return the number of dominoes that are similar to any other domino.

$dominos[i] = [a, b] and $dominos[j] = [c, d] are same if either (a = c and b = d) or (a = d and b = c).

Example 1

Input: @dominos = ([1, 3], [3, 1], [2, 4], [6, 8])
Output: 2

Similar Dominos: $dominos[0], $dominos[1]

Example 2

Input: @dominos = ([1, 2], [2, 1], [1, 1], [1, 2], [2, 2])
Output: 3

Similar Dominos: $dominos[0], $dominos[1], $dominos[3]

Task 2: Boomerang

Submitted by: Mohammad Sajid Anwar

You are given an array of points, (x, y).

Write a script to find out if the given points are a boomerang.

A boomerang is a set of three points that are all distinct and not in a straight line.

Example 1

Input: @points = ( [1, 1], [2, 3], [3,2] )
Output: true

Example 2

Input: @points = ( [1, 1], [2, 2], [3, 3] )
Output: false

Example 3

Input: @points = ( [1, 1], [1, 2], [2, 3] )
Output: true

Example 4

Input: @points = ( [1, 1], [1, 2], [1, 3] )
Output: false

Example 5

Input: @points = ( [1, 1], [2, 1], [3, 1] )
Output: false

Example 6

Input: @points = ( [0, 0], [2, 3], [4, 5] )
Output: true
