Solution: Intersection of Two Arrays II

Explore how to solve the intersection of two arrays problem by leveraging hash maps to count element frequencies. This lesson helps you implement an efficient approach that returns all common elements with correct multiplicities and understand its time and space complexity analysis.

Statement

Given two integer arrays nums1 and nums2, return an array representing their intersection. Each element in the result should appear exactly as many times as it appears in both arrays. The result may be returned in any order.

Constraints:

  • 11 \leq nums1.length, nums2.length 1000\leq 1000 ...
