SPONSOR
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: Pattern 132
Submitted by: Mohammad S Anwar
You are given a list of integers, @list.
Write a script to find out subsequence that respect Pattern 132. Return empty array if none found.
Pattern 132 in a sequence (a[i], a[j], a[k]) such that
i < j < k and a[i] < a[k] < a[j].
Example 1
Input: @list = (3, 1, 4, 2)
Output: (1, 4, 2) respect the Pattern 132.
Example 2
Input: @list = (1, 2, 3, 4)
Output: () since no susbsequence can be found.
Example 3
Input: @list = (1, 3, 2, 4, 6, 5)
Output: (1, 3, 2) if more than one subsequence found then return the first.
Example 4
Input: @list = (1, 3, 4, 2)
Output: (1, 3, 2)
Task 2: Range List
Submitted by: Mohammad S Anwar
You are given a sorted unique integer array, @array.
Write a script to find all possible Number Range i.e [x, y] represent range all integers from x and y (both inclusive).
Each subsequence of two or more contiguous integers
Example 1
Input: @array = (1,3,4,5,7)
Output: [3,5]
Example 2
Input: @array = (1,2,3,6,7,9)
Output: [1,3], [6,7]
Example 3
Input: @array = (0,1,2,4,5,6,8,9)
Output: [0,2], [4,6], [8,9]
