Given two arrays, write a function to compute their intersection. Example: Givennums1 =[1, 2, 2, 1],nums2 =[2, 2], return[2]. Note: Each element in the result must be unique. The result can be in any order. 一道easy的题目,感觉诸多提示如unique,in any order。感觉使用set是一个非...
Given two arrays, write a function to compute their intersection. Example: Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. Note: 1、Each element in the result must be unique. 2、The result can be in any order. 要完成的函数: vector<int> intersection(vector<int>& ...

If you want to get the intersection of arrays, use the intersect1d() method. Intersection means finding common elements between two arrays.
If the two elements are the same, forward both pointers and put the element to the return array If the two elements are not the same, move the smaller one's pointer forward Keep doing the above two steps until it hit the end of any one of the arrays. class Solution: def intersect(se...
