1. 原题链接 https://leetcode.com/problems/3sum-closest/description/ 2. 题目要求 数组S = nums[n]包含n个整数,找出S中三个整数a,b,c,使得a+b+c=sum,sum最接近给定的目标整数target,返回sum. 3. 解题思路 采用与第15题相同的思路(第15题链接),不过要引入两个整型变量min和result. min用来保存当前sum和target的最小差值 result用来保存最小差值时的sum,最终的resul…

n数求和,固定n-2个数,最后两个数在连续区间内一左一右根据当前求和与目标值比较移动,如果sum<target,移动较小数,否则,移动较大数 重复数处理: 使i为左至右第一个不重复数:while(i != 0 && i<n-2 && a[i] == a[i-1]) i++; 使r为右至左第一个不重复数(原序最后一个):while(r>i && r+1<n && a[r] == a[r+1]) r--; 15. 3Sum…

乘风破浪:LeetCode真题_016_3Sum Closest 一.前言      这一次,问题又升级了,寻找的是三个数之和最靠近的某个数,这是非常让人难以思考的,需要把三个数相加之后和最后给的目标进行比较,看看接近的程度,选择最接近的.不一定是等于目标.那么我们又该怎么做呢?? 二.3Sum Closest 2.1 问题 2.2 分析与解决 由上面的题意我们可以知道上一次的3sum所用的算法这边可能用不上了,需要进行改进.比如我们可以设想一个变量使得a+b+c≠target,但是a+b+c+…

一.题目链接:https://leetcode.com/problems/3sum-closest/ 二.题目大意: 给定一个数组A和一个目标值target,要求从数组A中找出3个数来,使得这三个数的和最接近target. 三.题解: 这道题实质就是3sum(http://www.cnblogs.com/wangkundentisy/p/9079622.html)问题的变形,而且题目假设的是解是唯一的,所以该题甚至都不用考虑重复情况了.所以只需在3sum问题中,判断下三个元素的和与target的…
