+Task 1: Broken Keyboard
+Submitted by: Mohammad Sajid Anwar
+
+You are given a string containing English letters only and also you are given broken keys.
+Write a script to return the total words in the given sentence can be typed completely.
+
+Example 1
+Input: $str = 'Hello World', @keys = ('d')
+Output: 1
+
+With broken key 'd', we can only type the word 'Hello'.
+
+Example 2
+Input: $str = 'apple banana cherry', @keys = ('a', 'e')
+Output: 0
+
+Example 3
+Input: $str = 'Coding is fun', @keys = ()
+Output: 3
+
+No keys broken.
+
+Example 4
+Input: $str = 'The Weekly Challenge', @keys = ('a','b')
+Output: 3
+
+Example 5
+Input: $str = 'Perl and Python', @keys = ('p')
+Output: 1
