The Weekly Challenge

HEADLINES

Welcome to the Week #226 of The Weekly Challenge.

Let us all welcome a new member, Dan Friedman, an expert Perl hacker to the Team PWC.

We got the detailed conversation with the latest champion, Avery Adams. You really don’t want to miss it. Please do check it out yourself.

As you all know, we had The Perl and Raku Conference 2023 last week. I had the pleasure to attend the conference. I was lucky to meet so many members of Team PWC. I would like to specially mention, Bruce Gray, Joelle Maslak, Saif Ahmed, Dave Cross, Steven Lembark, Kang-min Liu and Walt Mankowski.

It was pleasant meeting, Sarah Gray, wife of Bruce Gray. She was helping the team running the conference smoothly.

Presentation @ TPRC 2023

I would like to thank, Early Club Members, for helping me with review of weekly challenge tasks every week. You help me avoid embarrassment. If anyone willing to join the club, please feel free to send me request and I will add you to the club.

I am aware that sometimes task is not clearly explained and make it harder for you all to solve it. I appreciate your understanding and taking the effort to solve it still. You all deserve, a big round of applause.

Today, we are giving away Coupon #48 to PokGoPun 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: Shuffle String

Submitted by: Mohammad S Anwar

You are given a string and an array of indices of same length as string.

Write a script to return the string after re-arranging the indices in the correct order.

Example 1

Input: $string = 'lacelengh', @indices = (3,2,0,5,4,8,6,7,1)
Output: 'challenge'

Example 2

Input: $string = 'rulepark', @indices = (4,7,3,1,0,5,2,6)
Output: 'perlraku'

Task 2: Zero Array

Submitted by: Mohammad S Anwar

You are given an array of non-negative integers, @ints.

Write a script to return the minimum number of operations to make every element equal zero.

In each operation, you are required to pick a positive number less than or equal to the smallest element in the array, then subtract that from each positive element in the array.

Example 1:

Input: @ints = (1, 5, 0, 3, 5)
Output: 3

operation 1: pick 1 => (0, 4, 0, 2, 4)
operation 2: pick 2 => (0, 2, 0, 0, 2)
operation 3: pick 2 => (0, 0, 0, 0, 0)

Example 2:

Input: @ints = (0)
Output: 0

Example 3:

Input: @ints = (2, 1, 4, 0, 3)
Output: 4

operation 1: pick 1 => (1, 0, 3, 0, 2)
operation 2: pick 1 => (0, 0, 2, 0, 1)
operation 3: pick 1 => (0, 0, 1, 0, 0)
operation 4: pick 1 => (0, 0, 0, 0, 0)
