-    Data validation
-    ---------------
-    This utility function contains two sub-funtions :
-    
-    1) make_upper_case() : converts the characters in a string to upper case .
-    
-    2) make_lower_case() : converts the characters in a string to lower case . 
-
-    Time complexity
-    ---------------
-    O(n), where n is the length of the string .
