The Weekly Challenge

HEADLINES

Welcome to the Week #204 of The Weekly Challenge.

Every time, I try harder I find myself in a big trouble. I should take it easy, rather. You all must have noticed in recent weeks, the delay in the processing the regular contributions. It is all because of mess in my head. I am trying my best.

Last week, we had 2 new members joining Team PWC. Chicagoist and BarrOff. Welcome on board, I hope you find the weekly challenge fun to play with.

Today, we are giving away Coupon #27 to Dave Jacoby for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

The combined effort of the team, once again, made us cross over the line, little late though. Having this week, the margin is a bit big, so I doubt we get over the magic number. Prove me wrong. Thank you Team PWC for your support and contributions..

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: Monotonic Array

Submitted by: Mohammad S Anwar

You are given an array of integers.

Write a script to find out if the given array is Monotonic. Print 1 if it is otherwise 0.

An array is Monotonic if it is either monotone increasing or decreasing.

Monotone increasing: for i <= j , nums[i] <= nums[j]
Monotone decreasing: for i <= j , nums[i] >= nums[j]

Example 1

Input: @nums = (1,2,2,3)
Output: 1

Example 2

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

Example 3

Input: @nums = (6,5,5,4)
Output: 1

Task 2: Reshape Matrix

Submitted by: Mohammad S Anwar

You are given a matrix (m x n) and two integers (r) and (c).

Write a script to reshape the given matrix in form (r x c) with the original value in the given matrix. If you can’t reshape print 0.

Example 1

Input: [ 1 2 ]
       [ 3 4 ]

       $matrix = [ [ 1, 2 ], [ 3, 4 ] ]
       $r = 1
       $c = 4

Output: [ 1 2 3 4 ]

Example 2

Input: [ 1 2 3 ]
       [ 4 5 6 ]

       $matrix = [ [ 1, 2, 3 ] , [ 4, 5, 6 ] ]
       $r = 3
       $c = 2

Output: [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]

        [ 1 2 ]
        [ 3 4 ]
        [ 5 6 ]

Example 3

Input: [ 1 2 ]

       $matrix = [ [ 1, 2 ] ]
       $r = 3
       $c = 2

Output: 0

Last date to submit the solution 23:59 (UK Time) Sunday 19th February 2023.
