Elements in a triplet (a,b,c) must be in non-descending order. (ie,a≤b≤c) The solution set must not contain duplicate triplets. For example, given array S = {-1 0 1 2 -1 -4}, A solution set is: (-1, 0, 1) (-1, -1, 2) 题解: 3 Sum是two Sum的变种,可以利用two ...

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 solution set mus...
的情况时,其实只用到了 4 , 3 长度的情况,而长度为 1 2 的子串情况其实已经不需要了。但是由于我们并不是用 P 数组的下标进行的循环,没有想到优化的方法。 之后看到了另一种动态规划的思路 https://leetcode.com/problems/longest-palindromic-substringdiscuss/2921/Share-my-Java-solution-using-...
