Find Common elements in three array given that all three arrays are sorted
Given an array containing only 0s, 1s and 2s in a random order, arrange the array such that all 0s come before 1s which in turn come before all 2s
Input - [1,2,0,1,2,1,0,1,2,1,0]
Output - [0,0,0,1,1,1,1,1,2,2,2]

Quicksort Running Time: Quick sort average case is O(n log n) each level takes O(n) but splitting the data is O(log n) O(n) * O(log n) = O(n log n) Worse case is O(log n2) if pivot is smallest value, each level is O(n) and splitting the data is O(n) O(n) * O(n) = O(n2)
