Solution: Intersection of Two Arrays
Explore how to efficiently compute the unique intersection of two integer arrays using hash map data structures. This lesson helps you understand how to track elements from one array and check their presence in the other with linear time complexity. You will learn to implement the solution step-by-step while avoiding duplicates and optimizing both time and space complexity.

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
arr1.length,arr2.length...
