题目地址:https://oj.leetcode.com/problems/two-sum/ Two Sum Given an array of integers, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than...
但是,数组中同一个元素不能使用两遍。 给定nums = [2,7,11,15],target=9因为 nums[0] + nums[1] =2+7=9所以返回 [0,1] #使用字典,O(n)class Solution: def twoSum(self, nums: List[int], target:int) -> List[int]: dic={}length=len(nums)fori in range(length):iftarget-nums[i]n...
难度:简单 https://leetcode-cn.com/problems/two-sum/ 给定一个整数数组nums和一个整数目标值target,请你在该数组中找出和为目标值target的那两个整数,并返回它们的数组下标。 你可以假设每种输入只会对应一个答案。但是,数组中同一个元素在答案里不能重复...

题目来源：力扣（LeetCode）https://leetcode-cn.com/problems/two-sum 二、解答(java)：方案一：循环遍历，逐个尝试,时间复杂度为O(n^2)class Solution { public int[] twoSum(int[] nums, int target) { int a=0; int b=0; for(int i=0;i<nums.length;i++){ for(int j=i+...
3 输入与输出：vector<int> twoSum(vector<int>& nums, int target){}完成这个成员函数解决问题。4 思路：这个可以使用哈希表一次搞定这个问题。当我们扫描整个数组，检查当前元素的补码是否已经存在于表中。如果存在，我们已经找到解决方案并立即返回。如果不存在就向表中插入该元素。5 这一步提供我的打败97%的人...
