Solution: Intersection of Two Arrays
Explore how to find the unique intersection of two integer arrays by using hash maps to track elements. Learn to implement a solution that processes each array efficiently, avoiding duplicates and minimizing time complexity to O(n + m). This lesson guides you through designing and coding the intersection logic, helping you apply hash map concepts to optimize array-based problems in Go.

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...
