Find Common Elements in Two Arrays – Intersection of two Arrays

Given two sorted arrays, Write a code to find common elements in two arrays. In other words, we have to write a code to find the intersection of two arrays.

Find Common Elements in Two Arrays

Let’s assume following two sorted arrays arr1[] and arr2[].

int arr1[] = {2,  3,  4,  5,  6};
int arr2[] = {4,  6,  7,  8,  9};

So the common elements in these two arrays is 4 and 6.
