Given a provided array, determine how many groups of a specified size exist.

For the array [1,1,1,2,2,2,3,3,3,4,5,6,7] , there are 7 groups with at least one, 3 groups with at least 2, and 3 groups with at least 3. A group is a series of same values. 1 1 1 is a group of 3, but it also is a group of 1 and 2. To count as a group, all values must be the same. 1 1 1 is a group of 3 because there are 3 1s in a row.

Sample Data :

3 3 3 3 3 9 4 4 4 5 5 5 5 6 6 7 7 7 8 8 8 8 8 8 8 8

1 2 3 4 5 6 7 8 9

1 1 1 2 1 1 3 3 3 3 3 3 3 3 3 3 4 4 4 5 4 4 4 6

Sample Output :

[3, 3, 3, 3, 3, 9, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 7, 7, 8, 8, 8, 8, 8, 8, 8, 8]
