Solution: Intersection of Two Arrays

Explore how to solve the intersection of two arrays problem by applying hash map techniques. Learn to efficiently identify unique common elements between arrays while understanding the tradeoffs in time and space complexity for optimized coding solutions.

We'll cover the following...

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

  • 1≤1 \leq arr1.length, arr2.length ≤1000\leq 1000 ...
