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...
Output: [2,2] Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4] Output: [4,9] Note: Each element in the result should appear as many times as it shows in both arrays. The result can be in any order. Follow up: What if the given array is already sorted? How w...
Input: nums1 =[4,9,5], nums2 =[9,4,9,8,4] Output:[4,9] 1. 2. Note: Each element in the result should appear as many times as it shows in both arrays. The result can be in any order. Follow up: What if the given array is already sorted? How would you optimize your al...

这道题就是Intersection of Two Arrays的加强版。同样用HashMap来做。需要考虑在intersection中重复的次数。 代码如下: public class Solution { public int[] intersection(int[] nums1, int[] nums2) { HashMap<Integer, Integer> map = new HashMap<Integer, Integer>(); HashMap<Integer, Integer> resultM...
Given a 2D integer array nums where nums[i] is a non-empty array of distinct positive integers, return the list of integers that are present in each array of nums sorted in ascending order. Example 1: Input: nums = [[3,1,2,4,5],[1,2,3,4],[3,4,5,6]] Output: [3,4] ...
349. Intersection of Two Arrays # 题目# 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...
