(in C please) A cluster in an array is a series of 2 or more consecutive elements of the same value. Write a program that prints the number of clusters in a given array.

You may assume that maximum size of array is 100, contains only positive integers, the last input from the user is -1 to mark the end of the list.

Examples:

Input:

1 1 2 2 3 4 4 4 6 7 4 4 -1

Output:

Input Array is : 1, 1, 2, 2, 3, 4, 4, 4, 6, 7, 4, 4, -1,

Total number of clusters found = 4
