【leetcode75】Intersection of Two Arrays(数组的交集) 题目描述: 给定两个数组求他们的公共部分,输出形式是数组,相同的元素只是输出一次 例如: nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. 原文描述: Given two arrays, write a function to compute their intersection. Example: Given ...
LeetCode题解之 Intersection of Two Arrays 1、题目描述 2、问题分析 借助于set来做。 3、代码 1 class Solution { 2 public: 3 vector<int> intersection(vector<int>& nums1, vector<int>& nums2) { 4 vector<int> res; 5 set<int> s1; 6 set<int> s2; 7 for( auto & n : nums1) 8 s1...
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>& ...
Leetcode: Intersection of Two Arrays Given two arrays, write a function to compute their intersection. Example: Given nums1 = [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....
Can you solve this real interview question? Intersection of Two Arrays - Given two integer arrays nums1 and nums2, return an array of their intersection. Each element in the result must be unique and you may return the result in any order. Example 1:
1 -- set_intersection(交集) 2 -- set_union(并集) 3 -- set_difference(差集) 4 -- set_symeetric_difference(对称差集) 去重的unique。 classSolution{ public: vector<int> unique_element_in_vector(vector<int>& v){ vector<int>::iterator vector_iterator; ...
Can you solve this real interview question? Intersection of Two Arrays II - Given two integer arrays nums1 and nums2, return an array of their intersection. Each element in the result must appear as many times as it shows in both arrays and you may retur
LeetCode 350. Intersection of Two Arrays II Given two arrays, write a function to compute their intersection. Example:Given nums1 = [1, 2, 2, 1] , nums2 = [2, 2] , return [2, 2] Note: Each element in the result should appear as many times as it......
LeetCode--350. Intersection of Two Arrays II(两个数组的交集)Python 题目: 给定两个数组,返回这两个数组的交集。 解题思路: 使用哈希表用来存储第一个数组中的内容。再遍历第二个数组,看该数组的数字是否在哈希表中,在则将该数字加入输出的列表中。 代码(Python):......
