How do you know if all elements in an array are same?

Given an array, check whether all elements in an array are same or not. Examples: Input : “Geeks”, “for”, “Geeks” Output : Not all Elements are Same Input : 1, 1, 1, 1, 1 Output : All Elements are Same. Method 1 (Hashing) We create an empty HashSet, insert all elements into it, then we finally see if size of the HashSet is one or not.
