Task 1: Broken Keys

Submitted by: Mohammad Sajid Anwar

You are given a sentence, $sentence and list of broken keys @keys.

Write a script to find out how many words can be typed fully.

Example 1

Input: $sentence = "Perl Weekly Challenge", @keys = ('l', 'a')
Output: 0

Example 2

Input: $sentence = "Perl and Raku", @keys = ('a')
Output: 1

Only Perl since the other word two words contain 'a' and can't be typed fully.

Example 3

Input: $sentence = "Well done Team PWC", @keys = ('l', 'o')
Output: 2

Example 4

Input: $sentence = "The joys of polyglottism", @keys = ('T')
Output: 2

Task 2: Replace Digits

Submitted by: Mohammad Sajid Anwar

You are given an alphanumeric string, $str, where each character is either a letter or a digit.

Write a script to replace each digit in the given string with the value of the previous letter plus (digit) places.

Example 1

Input: $str = 'a1c1e1'
Ouput: 'abcdef'

shift('a', 1) => 'b'
shift('c', 1) => 'd'
shift('e', 1) => 'f'

Example 2

Input: $str = 'a1b2c3d4'
Output: 'abbdcfdh'

shift('a', 1) => 'b'
shift('b', 2) => 'd'
shift('c', 3) => 'f'
shift('d', 4) => 'h'

Example 3

Input: $str = 'b2b'
Output: 'bdb'

Example 4

Input: $str = 'a16z'
Output: 'abgz'
