The Weekly Challenge

HEADLINES

Welcome to the Week #228 of The Weekly Challenge.

I would like to share with the Team PWC that I am going on 3 weeks holiday to India this Friday 4th Aug 2023. During the holiday, there would be big delays in accepting the contributions and updating the charts.

Today, we are giving away Coupon #50 to Stephen G. Lynn 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.

In the given array every element is unique.

Task 2: Empty Array

Submitted by: Mohammad S Anwar

You are given an array of integers in which all elements are unique.

Write a script to perform the following operations until the array is empty and return the total count of operations.

If the first element is the smallest then remove it otherwise move it to the end.

Example 1

Input: @int = (3, 4, 2)
Ouput: 5

Operation 1: move 3 to the end: (4, 2, 3)
Operation 2: move 4 to the end: (2, 3, 4)
Operation 3: remove element 2: (3, 4)
Operation 4: remove element 3: (4)
Operation 5: remove element 4: ()

Example 2

Input: @int = (1, 2, 3)
Ouput: 3

Operation 1: remove element 1: (2, 3)
Operation 2: remove element 2: (3)
Operation 3: remove element 3: ()
