The Weekly Challenge

HEADLINES

Welcome to the Week #206 of The Weekly Challenge.

We have one more addition to the Team PWC, an experience Perl hacker by the name Avery Adams. Thanks for sharing solutions in Perl.

E. Alvarez is back to blogging again and we have another gem from him. Thank you.

I would like to thank Team PWC members for the kind messages and asking about me. It means a lot. Please forgive me if you don’t hear from me. Every word of yours means a world to me. It would be unfair if I take names here but you know who I am talking about.

If you see delay from my side then please accept my apology as I am trying my best to deal with the situation to the best of my ability. I can’t talk more in public but if you are keen then we can have one-2-one through email.

Today, we are giving away Coupon #29 to Lubos Kolouch for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

I am overwhelmed by the contributions in Perl last week. Even Raku was nearly half of Perl. With regard to the blog, we have regular bloggers who keep us busy all week. I would like to take this opportunity to than each and every members of Team PWC. The discussion is getting intensed as we grow. I really enjoy the company of such a cool bunch of techies.

Sometimes, one week is not enough to go through each contributions. I have noticed the quality of blogs have improved too. Kudos to the team once again.

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.

Please find past solutions by respected guests. Please share your creative solutions in other languages.

Task 1: Shortest Time

Submitted by: Mohammad S Anwar

You are given a list of time points, at least 2, in the 24-hour clock format HH:MM.

Write a script to find out the shortest time in minutes between any two time points.

Example 1

Input: @time = ("00:00", "23:55", "20:00")
Output: 5

Since the difference between "00:00" and "23:55" is the shortest (5 minutes).

Example 2

Input: @array = ("01:01", "00:50", "00:57")
Output: 4

Example 3

Input: @array = ("10:10", "09:30", "09:00", "09:55")
Output: 15

Task 2: Array Pairings

Submitted by: Mohammad S Anwar

You are given an array of integers having even number of elements..

Write a script to find the maximum sum of the minimum of each pairs.

Example 1

Input: @array = (1,2,3,4)
Output: 4

Possible Pairings are as below:
a) (1,2) and (3,4). So min(1,2) + min(3,4) => 1 + 3 => 4
b) (1,3) and (2,4). So min(1,3) + min(2,4) => 1 + 2 => 3
c) (1,4) and (2,3). So min(1,4) + min(2,3) => 2 + 1 => 3

So the maxium sum is 4.

Example 2

Input: @array = (0,2,1,3)
Output: 2

Possible Pairings are as below:
a) (0,2) and (1,3). So min(0,2) + min(1,3) => 0 + 1 => 1
b) (0,1) and (2,3). So min(0,1) + min(2,3) => 0 + 2 => 2
c) (0,3) and (2,1). So min(0,3) + min(2,1) => 0 + 1 => 1

So the maximum sum is 2.

Last date to submit the solution 23:59 (UK Time) Sunday 5th March 2023.
