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 return the result in any order. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2,2] ...
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【数组】---349. Intersection of Two Arrays(两个数组的交集) 1、题目描述 2、分析 给定两个数组,编写一个函数来计算它们的交集。可以从例子上看出,这道题只需要找到两个数组中相同的数字就好,所以现将第一个数组放入一个set,set里没有重复的元素,并且是排好序的。之后遍历第二个数组看第二个数组...
LeetCode笔记:350. Intersection of Two Arrays II 问题: 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 a......
Given two arrays, write a function to compute their intersection. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2,2] Example 2: Input: n
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):......
LeetCode #350. Intersection of Two Arrays II 题目 350. Intersection of Two Arrays II 解题方法 设置两个字典dic1和dic2分别计数nums1和nums2,遍历nums2做一个set记录其中存在于dic1中的成员,然后遍历这个set中的成员,找到其在dic1和dic2中的值,取两个值的最小值count,然后在返回值中写count个这个成员...
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 II Description: Given two arrays, write a function to compute their intersection. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2,2] Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4]...
