+//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
