Solution: Check if Arrays are Disjoint

Let’s solve the Check if Arrays are Disjoint problem.

We'll cover the following


Given two arrays, determine whether or not they are disjoint.

Note: Arrays are disjoint if they have no common element between them.


  • 11 \leq arr1.length, arr2.length 103\leq 10^3
  • 105-10^5 \leq arr[i] 105\leq 10^5
