NEW MEMBERS
1) PJ Durai, an experienced Raku hacker.
2) Stuart Little, an experienced Perl/Raku hacker.
I am an amateur programmer (nothing but scripts for personal use); mostly Perl until recently, but with an increasing fascination for Raku. I expect I'd mostly be submitting Raku solutions.
Please find out How to contribute?, if you have any doubts.
Please give it a try to an excellent tool EZPWC created by respected member Saif Ahmed of Team PWC.

TASK #1 › Reverse Integer
Submitted by: Mohammad S Anwar
You are given an integer $N.
Write a script to reverse the given integer and print the result. Print 0 if the result doesn’t fit in 32-bit signed integer.
The number 2,147,483,647 is the maximum positive value for a 32-bit signed binary integer in computing.
Example 1:
Input: 1234
Output: 4321
Example 2:
Input: -1234
Output: -4321
Example 3:
Input: 1231230512
Output: 0
TASK #2 › Find Square
Submitted by: Mohammad S Anwar
You are given matrix of size m x n with only 1 and 0.
Write a script to find the count of squares having all four corners set as 1.
Example 1:
Input: [ 0 1 0 1 ]
[ 0 0 1 0 ]
[ 1 1 0 1 ]
[ 1 0 0 1 ]
Output: 1
Explanation:
There is one square (3x3) in the given matrix with four corners as 1 starts at r=1;c=2.
[ 1 0 1 ]
[ 0 1 0 ]
[ 1 0 1 ]
Example 2:
Input: [ 1 1 0 1 ]
[ 1 1 0 0 ]
[ 0 1 1 1 ]
[ 1 0 1 1 ]
Output: 4
Explanation:
There is one square (4x4) in the given matrix with four corners as 1 starts at r=1;c=1.
There is one square (3x3) in the given matrix with four corners as 1 starts at r=1;c=2.
There are two squares (2x2) in the given matrix with four corners as 1. First starts at r=1;c=1 and second starts at r=3;c=3.
Example 3:
Input: [ 0 1 0 1 ]
[ 1 0 1 0 ]
[ 0 1 0 0 ]
[ 1 0 0 1 ]
Output: 0
Last date to submit the solution 23:59 (UK Time) Sunday 1st November 2020.
