从今天开始,每天至少一个算法题,督促自己,不管难易都整理一下。 https://leetcode.com/problems/two-sum/#/description
Given an array of integers, return indices of the two numbers such that they add up to a specific target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
Example: Given nums = [2, 7, 11, 15], target = 9,
Because nums[0] + nums[1] = 2 + 7 = 9, return [0, 1].
代码如下
public class Solution { public int[] twoSum(int[] nums, int target) { int[] temp=new int[2]; for(int i=0;i<nums.length;i++) { for(int j=i+1;j<nums.length;j++) { if(nums[i]+nums[j]==target) { temp[0]=i; temp[1]=j; } } } return temp; } }
