The Weekly Challenge

09. TASK #1: Greatest English Letter

HEADLINES

Welcome to the Week #264 of The Weekly Challenge.

Thank you, Andrew Shitov, for reviewing Raku solutions for the Week #262. There was a time when we used to have weekly reviews of both Perl and Raku solutions. It was very popular among the Team PWC members. Unfortunately it is discontinued for sometime now. I am happy that Andrew found spare time last week for us and shared his views. I am not sure if this would be regular from now. I would be more than happy even if we get after break, it doesn’t have to be every week.

Welcome back, Robert DiCicco after the break and thanks for sharing solution in Perl.

Last week, Asher Harvey-Smith, introduced a new programming language Hy and shared his contribution.

I would also like to thank, Archar Gelod, for taking up past challenges and sharing his creations in Nim. For all Nim fans, you must checkout his solutions. I am expecting it be part of Top #10 guest languages soon.

Please keep sharing and spreading the word.

Task 1: Greatest English Letter

Submitted by: Mohammad Sajid Anwar

You are given a string, $str, made up of only alphabetic characters [a..zA..Z].

Write a script to return the greatest english letter in the given string.

A letter is greatest if it occurs as lower and upper case. Also letter ‘b’ is greater than ‘a’ if ‘b’ appears after ‘a’ in the English alphabet.

Example 1

Input: $str = 'PeRlwEeKLy'
Output: L

There are two letters E and L that appears as lower and upper.
The letter L appears after E, so the L is the greatest english letter.

Example 2

Input: $str = 'ChaLlenge'
Output: L

Example 3

Input: $str = 'The'
Output: ''

Task 2: Target Array

Submitted by: Mohammad Sajid Anwar

You are given two arrays of integers, @source and @indices. The @indices can only contains integers 0 <= i < size of @source.

Write a script to create target array by insert at index $indices[i] the value $source[i].

Example 1

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

@source  @indices  @target
0        0         (0)
1        1         (0, 1)
2        2         (0, 1, 2)
3        2         (0, 1, 3, 2)
4        1         (0, 4, 1, 3, 2)

Example 2

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

@source  @indices  @target
1        0         (1)
2        1         (1, 2)
3        2         (1, 2, 3)
4        3         (1, 2, 3, 4)
0        0         (0, 1, 2, 3, 4)

Example 3

Input: @source  = (1)
       @indices = (0)
Output: (1)
