The Weekly Challenge

HEADLINES

Welcome to the Week #214 of The Weekly Challenge.

Last week we decided to give away FREE book coupon to Leo Manfredi but unfortunately we don’t have his email address. I request Leo please share your email to perlweeklychallenge@yahoo.com so that the coupon can be shared with you.

I noticed something that most of the recently declared champions either not keen to share tech side of their life or a private person. I know it is optional but I find it really interesting to know the tech side of the champions. For example, if you checkout interview with Joelle Maslak, Adam Russell etc then you will understand what I mean. I really miss it.

We have new guest language, GP introduced by fellow Team PWC member BarrOff sharing solution to Task #1. With this addition, we now have 99 guest languages, just one short to another milestone.

Today, we are giving away Coupon #37 to Peter Meszaros for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

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.

Task 1: Rank Score

Submitted by: Mohammad S Anwar

You are given a list of scores (>=1).

Write a script to rank each score in descending order. First three will get medals i.e. G (Gold), S (Silver) and B (Bronze). Rest will just get the ranking number.

Using the standard model of giving equal scores equal rank, then advancing that number of ranks.

Example 1

Input: @scores = (1,2,4,3,5)
Output: (5,4,S,B,G)

Score 1 is the 5th rank.
Score 2 is the 4th rank.
Score 4 is the 2nd rank i.e. Silver (S).
Score 3 is the 3rd rank i.e. Bronze (B).
Score 5 is the 1st rank i.e. Gold (G).

Example 2

Input: @scores = (8,5,6,7,4)
Output: (G,4,B,S,5)

Score 8 is the 1st rank i.e. Gold (G).
Score 4 is the 4th rank.
Score 6 is the 3rd rank i.e. Bronze (B).
Score 7 is the 2nd rank i.e. Silver (S).
Score 4 is the 5th rank.

Example 3

Input: @list = (3,5,4,2)
Output: (B,G,S,4)

Example 4

Input: @scores = (2,5,2,1,7,5,1)
Output: (4,S,4,6,G,S,6)

Task 2: Collect Points

Submitted by: Mohammad S Anwar

You are given a list of numbers.

You will perform a series of removal operations. For each operation, you remove from the list N (one or more) equal and consecutive numbers, and add to your score N × N.

Determine the maximum possible score.

Example 1:

Input: @numbers = (2,4,3,3,3,4,5,4,2)
Output: 23

We see three 3's next to each other so let us remove that first and collect 3 x 3 points.
So now the list is (2,4,4,5,4,2).
Let us now remove 5 so that all 4's can be next to each other and collect 1 x 1 point.
So now the list is (2,4,4,4,2).
Time to remove three 4's and collect 3 x 3 points.
Now the list is (2,2).
Finally remove both 2's and collect 2 x 2 points.
So the total points collected is 9 + 1 + 9 + 4 => 23.

Example 2:

Input: @numbers = (1,2,2,2,2,1)
Output: 20

Remove four 2's first and collect 4 x 4 points.
Now the list is (1,1).
Finally remove the two 1's and collect 2 x 2 points.
So the total points collected is 16 + 4 => 20.

Example 3:

Input: @numbers = (1)
Output: 1

Example 4:

Input: @numbers = (2,2,2,1,1,2,2,2)
Output: 40

Remove two 1's = 2 x 2 points.
Now the list is (2,2,2,2,2,2).
Then reomove six 2's = 6 x 6 points.

Last date to submit the solution 23:59 (UK Time) Sunday 30th April 2023.
