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 2022. 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 2022. 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: Zip List

Submitted by: Mohammad S Anwar

You are given two list @a and @b of same size.

Create a subroutine sub zip(@a, @b) that merge the two list as shown in the example below.

Example

Input:  @a = qw/1 2 3/; @b = qw/a b c/;
Output: zip(@a, @b) should return qw/1 a 2 b 3 c/;
        zip(@b, @a) should return qw/a 1 b 2 c 3/;

Task 2: Unicode Makeover

Submitted by: Mohammad S Anwar

You are given a string with possible unicode characters.

Create a subroutine sub makeover($str) that replace the unicode characters with ascii equivalent. For this task, let us assume it only contains alphabets.

Example 1

Input: $str = 'ÃÊÍÒÙ';
Output: 'AEIOU'

Example 2

Input: $str = 'âÊíÒÙ';
Output: 'aEiOU'
