Our solo sponsor Pete Sergeant has been a great support to keep us motivated. We are lucky that he agreed to continue the journey with us in the year 2023. I would like to personally thank Pete and his entire team for their generosity. It would be great if we could add few more to sponsor the prize money so that we could go back and declare weekly champions as we have done in the past. I hope and wish this will become possible in 2023. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If an organisation comes forward and supports us then that would be the ultimate achievement.

Task 1: Toeplitz Matrix

Submitted by: Mohammad S Anwar

You are given a matrix m x n.

Write a script to find out if the given matrix is Toeplitz Matrix.

A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same elements.

Example 1

Input: @matrix = [ [4, 3, 2, 1],
                   [5, 4, 3, 2],
                   [6, 5, 4, 3],
                 ]
Output: true

Example 2

Input: @matrix = [ [1, 2, 3],
                   [3, 2, 1],
                 ]
Output: false

Task 2: Split Same Average

Submitted by: Mohammad S Anwar

You are given an array of integers.

Write a script to find out if the given can be split into two separate arrays whose average are the same.

Example 1:

Input: @nums = (1, 2, 3, 4, 5, 6, 7, 8)
Output: true

We can split the given array into (1, 4, 5, 8) and (2, 3, 6, 7).
The average of the two arrays are the same i.e. 4.5.

Example 2:

Input: @list = (1, 3)
Output: false
