题目地址 https://leetcode.com/problems/3sum-closest/ 题目描述 Given an array nums of n integers and an integer target, find three integers in nums such that the sum is closest to target. Return the sum of the three integers. You may assume that each input would have exactly one solution. Example: Given array nums = [-1, 2, 1, -4], and target = 1. The sum that is closest to the target is 2. (-1 + 2 + 1 = 2). 思路 这道题让我们求最接近给定值的三数之和,是在之前那道 3Sum 的基础上又增加了些许难度,那么这道题让返回这个最接近于给定值的值,即要保证当前三数和跟给定值之间的差的绝对值最小,所以需要定....
