一、三数之和:LeetCode 15 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 =0 ?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。 例如, 给定数组 nums =[-1, 0, 1, 2, -1, -4],满足要求的三元组集合为:[[-1, 0, 1],[-1, ...
then find another shortest subarray of sum target whose start index is >= i + 1. This way the two subarrays never overlap. This looks promising. But there is one more issue we need to address: how do we ensure that we are getting the best answer...
You have to find two non-overlapping sub-arrays of arr each with sum equal target. There can be multiple answers so you have to find an answer where the sum of the lengths of the two sub-arrays is minimum. Return the minimum sum of the lengths of the two required sub-arrays, or ret...

Leetcode: Find First and Last Position of Element in Sorted Array,Analysis: 这道题是二分查找SearchInsertPosition的变体,思路并不复杂,就是先用二分查找找到其中一个target,然后再往左右找到target的边缘。找边缘的方法跟二分查找仍然是一样的,只是相等的情况依
