Given two arrays, write a function to compute their intersection. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2] Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4] Output: [9,4] Note: Each element in the result must be unique. The…

给定两个数组,写一个函数来计算它们的交集.例子: 给定 num1= [1, 2, 2, 1], nums2 = [2, 2], 返回 [2].提示:    每个在结果中的元素必定是唯一的.    我们可以不考虑输出结果的顺序.详见:https://leetcode.com/problems/intersection-of-two-arrays/description/C++: class Solution { public: vector<int> intersection(vector<…
