Problem: Intersection of Two Arrays II
med
30 min
Explore how to find the intersection of two integer arrays where elements appear as many times as they do in both arrays. Understand the use of hash maps to implement this efficiently and practice solving similar problems with constraints on array length and element values.
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:
nums1.length,nums2.lengthnums1[i],nums2[i]
