You have an array size n and a constant k (whatever)

You can assume the the array is of int type (although it could be of any type)

Describe an algorithm that finds if there is an element(s) that repeats itself at least n/k times... if there is return one. Do so in linear time (O(n))

The catch: do this algorithm (or even pseudo-code) using constant memory and running over the array only twice
