HEADLINES
We have 2 new members joining the Team PWC this week, Paulo Custodio and Mimosinnet. We now have 211 active members across the globe. It would have been nice to plot the locations in the world map. I have done something similar for my Map::Tube module. I just have to find the time for the task.
Thank you Colin Crain for yet another quality reviews. I have had many positive feedbacks from Team PWC members about the same.
Stuart Little kept me on my toes with his non-stop Raku contributions ever since he joined the team. Proud to have him in the team.
Fortunately, we now have a match for him for Perl and he is the newest member Paulo Custodio. In the first week itself he contributed solutions to Week 89, Week 90 and Week 91.
This week, we had 20 contributions by guests in 11 different languages. I would like to THANK each and every guest contributors.

TASK #1 › Isomorphic Strings
Submitted by: Mohammad S Anwar
You are given two strings $A and $B.
Write a script to check if the given strings are Isomorphic. Print 1 if they are otherwise 0.
Example 1:
Input: $A = "abc"; $B = "xyz"
Output: 1
Example 2:
Input: $A = "abb"; $B = "xyy"
Output: 1
Example 3:
Input: $A = "sum"; $B = "add"
Output: 0
TASK #2 › Insert Interval
Submitted by: Mohammad S Anwar
You are given a set of sorted non-overlapping intervals and a new interval.
Write a script to merge the new interval to the given set of intervals.
Example 1:
Input $S = (1,4), (8,10); $N = (2,6)
Output: (1,6), (8,10)
Example 2:
Input $S = (1,2), (3,7), (8,10); $N = (5,8)
Output: (1,2), (3,10)
Example 3:
Input $S = (1,5), (7,9); $N = (10,11)
Output: (1,5), (7,9), (10,11)
Last date to submit the solution 23:59 (UK Time) Sunday 27th December 2020.
