LeetCode OJ:Three Sum(三数之和) Given an arraySofnintegers, are there elementsa,b,cinSsuch thata+b+c= 0? Find all unique triplets in the array which gives the sum of zero. Note: Elements in a triplet (a,b,c) must be in non-descending order. (ie,a≤b≤c) The solution set mu...
在leetcode的two sum 里面,主要有两种解法,一种是hashmap,一种是排序一样用双指针 http://www.noteanddata.com/leetcode-1-two-sum-solution-notes.html 现在变成3-sum,但是同样的思路仍然可以应用的。可以用hashmap保存每个数出现的次数,也可以排序以后用双指针。 同样的,这个题目主要要处理的一些tricky的数据...
Given an arraySofnintegers, find three integers inSsuch that the sum is closest to a given number, target. Return the sum of the three integers. You may assume that each input would have exactly one solution. For example, given array S = {-1 2 1 -4}, and target = 1. The sum tha...
