+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')

+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'
