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 ...
题目描述 给定一个包含 n 个整数的数组nums,判断nums中是否存在三个元素 a,b,c ,使得a b c 找出所有满足条件且不重复的三元组。 注意:答案中不可以包含重复的三元组。 解题思路 首先对数组从小到大排序,从一个数开始遍历,若该数大于 ,后面的数不可能与其相加和为 ,所以跳过 否则该数可能是满足要求的第一个数,这样可以转化为求后面数组中两数之和为该数的相反数的问题。定义两个指针一前 ...
