**Objective:** Given three sorted(ascending order) arrays of integers, find out all the common elements in them.

**Input:** Three sorted arrays.

**Output: **All the common elements.

**Examples** :

Array A = {1,2,3,4,5,6,7,8,9,10}; Array B = {1,3,5,6,7,8,12}; Array C = {2,3,4,5,8,9}; Common Elements are 3,5,8

**Approach: **

- Very Simple Solution.
- Navigate all three arrays(A,B,C) simultaneously using indexes say, i,j,k.
- if(A[i]==B[j]==C[k]) then print A[i] and do i++, j++, k++.
- if not then compare all A[i],B[j],C[k] and which ever is smaller, increase its index.
- Stop when any of these array gets over

**Complete Code:**

**Output:**

Common Elements are : 3 5 8
