Solution: Intersection of Two Arrays II

Understand how to solve the Intersection of Two Arrays II problem by building a frequency hash map from one array and matching elements from the second. This lesson helps you efficiently return intersecting elements with correct counts, emphasizing optimized time and space complexity.

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 ...
