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...
three sum 问题 此题摘自http://www.leetcode.com/onlinejudge 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...
之前有道算法题,是求两数之和,所以想法就是先遍历数组,固定当前元素,并求出当前元素的相反数,即剩下两个数的和sum;然后转化成 twoSum;最后去重。 本地跑是没问题的,但是,在力扣上提交代码,等待系统判分后,执行结果是超出时间限制——系统给的输入是好大一段数组,里面得有几百个数字吧?!🤣所以下面的代码适...

【Leetcode】3Sum 【wrong】 题目: S of n integers, are there elements a, b, c in S such that a + b + c Note: 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....
这道题作为 leetcode 的第 15 道题,看起来似曾相识。 大概思路可以有下面几种: 暴力解法 数组排序+二分 Hash 优化 双指针 v1-暴力解法 思路 直接3 次循环,找到符合结果的数据返回。 这种最容易想到,一般工作中也是我们用到最多的。 当然也必定超时。
