Find common elements in two sorted arrays | SDE Sheet | Hashing

In this video we will see how to find all common elements from three arrays sorted in non-decreasing order. Examples: Input: ar1[] = {1, 5, 5} ar2[] = {3, 4, 5, 5, 10} ar3[] = {5, 5, 10, 20} Output: 5, 5 Check out the video to see how we implement this!!
