Problem: Intersection of Two Arrays

easy
15 min
Explore how to solve the problem of finding the intersection of two integer arrays with unique elements. Understand the use of hash maps to implement an efficient solution and practice applying this pattern in a hands-on coding environment.

Statement

You are given two integer arrays, arr1 and arr2. Your task is to return a new array containing the intersection of both arrays.

  • Each element in the result must be unique.

  • The order of the elements in the result does not matter.

Constraints

  • 11 \leq arr1.length, arr2.length 1000\leq 1000

  • 00 \leqarr1[i], arr2[i] 1000\leq 1000
