Challenge 2: Check if Arrays are Disjoint

Problem statement

You have to implement the bool isDisjoint(int[] arr1, int[] arr2, int size1, int size2) function, which checks whether two given arrays are “disjoint” or not.

Two arrays are “disjoint” if there are no common elements between them. The assumption is that there are no duplicate elements in each array.

Input

This is two arrays of integers and their lengths.

Output

It returns true if the two arrays are disjointed. If not, it returns false.

Sample Input

arr1 = {9,4,3,1,-2,6,5}
arr2 = {7,10,8}

Sample output

true
