【leetcode python】Intersection of Two Arrays #-*- coding: UTF-8 -*- #求两个集合的交集 class Solution(object): def intersection(self, nums1, nums2): resultList=list(set(nums1).intersection(set(nums2))) return resultList sol=Solution() print sol.intersection(nums1 =[1, 2, 2, 1]...
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>& ...

python 两个数组的交集 intersection of two arrays,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。classSolution(object):defintersection(self,nums1,n
349. Intersection of Two Arrays刷题笔记 考察集合的交运算。python的set底层是用哈希表实现的 class Solution: def intersection(self, nums1: List[int], nums2: List[int]) -> List[int]: return list(set(nums1) & set(nums2)) 1. 2.
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...
