Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0? Find all unique triplets in the array which gives the sum of zero. Note: The solution set must not contain duplicate triplets. For example, given array S = [-1,…

Given an array S of n integers, are there elements a, b, c in S such that a + 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 solutio…

原题重述:(点击图片可以进入来源链接) 这到题目的中文解释是, 输入一个数组,例如{-1 0 1 2 -1 -4},从数组中找三个数(a,b,c),使得其和0,输出所有的(a,b,c)组合. 要求abc不能重复,并且a<=b<=c. 拿到这个题目的时候,其实每个程序猿都能想到如下的算法,也就是暴力破解,其时间复杂度为o(n^3): for(int i=0;i<nums.length;i++){ for(int j=i+1;j<nums.length;j++){ for(int k=…

Given an array S of n integers, find three integers in S such 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…
