题目: 给定一个数组,和一个指定的值,找出数组中3个数,它的和最接近这个指定值,并返回这个和. 解法: 和上一题找3个数的和为0一样,先排序再遍历,这一次不需要记录路径. 代码: class Solution { public: int threeSumClosest(vector<int> &num, int target) { int result, min_gap = INT_MAX; sort(num.begin(), num.end()); //先排序 ; a < nu…

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…
