Add to List 
Find all common numbers in given three sorted arrays.
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
Code:
Common Elements are : 3 5 8
