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: Registration Number

Submitted by: Mohammad S Anwar

You are given a list of words and a random registration number.

Write a script to find all the words in the given list that has every letter in the given registration number.

Example 1

Input: @words = ('abc', 'abcd', 'bcd'), $reg = 'AB1 2CD'
Output: ('abcd')

The only word that matches every alphabets in the given registration number is 'abcd'.

Example 2

Input: @words = ('job', 'james', 'bjorg'), $reg = '007 JB'
Output: ('job', 'bjorg')

Example 3

Input: @words = ('crack', 'road', 'rac'), $reg = 'C7 RA2'
Output: ('crack', 'rac')

Task 2: Word Stickers

Submitted by: Mohammad S Anwar

You are given a list of word stickers and a target word.

Write a script to find out how many word stickers is needed to make up the given target word.

Example 1:

Input: @stickers = ('perl','raku','python'), $word = 'peon'
Output: 2

We just need 2 stickers i.e. 'perl' and 'python'.
'pe' from 'perl' and
'on' from 'python' to get the target word.

Example 2:

Input: @stickers = ('love','hate','angry'), $word = 'goat'
Output: 3

We need 3 stickers i.e. 'angry', 'love' and 'hate'.
'g' from 'angry'
'o' from 'love' and
'at' from 'hate' to get the target word.

Example 3:

Input: @stickers = ('come','nation','delta'), $word = 'accommodation'
Output: 4

We just need 2 stickers of 'come' and one each of 'nation' & 'delta'.
'a' from 'delta'
'ccommo' from 2 stickers 'come'
'd' from the same sticker 'delta' and
'ation' from 'nation' to get the target word.

Example 4:

Input: @stickers = ('come','country','delta'), $word = 'accommodation'
Output: 0

as there's no "i" in the inputs.

Last date to submit the solution 23:59 (UK Time) Sunday 14th May 2023.
