Q:题目链接：Longest Substring Without Repeating Characters 先看题目要求： Given a string, find the length of the longest substring without repeating characters.Examples:Given “abcabcbb”, the answer is “abc”, whi

Q:题目链接：Two Sum 先看题目要求： Given an array of integers, return indices of the two numbers such that they add up to a specific target.You may assume that each input would have exactly one solution, an

Q:题目链接：Add Two Numbers 先看题目要求： You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digi

最近想系统地看看数据结构和算法，虽然实际工作中用到的不多（也许是水平不够不知道要用...）,但还是要多培养这方面的意识和思想，再加上大厂面试基本都要考察数据结构和算法，所以还是要把这块捡起来。当然，还是先从排序走起。上一次系统地看排序还是在大学里，刚接触编程不久，当时还是用C和Java写的，如今做了前端，C和Java几年不看也丢得差不多了，只能写写JS了。1.冒泡排序实现原理     

Q:题目链接：Longest Palindromic Substring 先看题目要求： Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000.Example1:Input: “babad”Output:

Q:题目链接：3Sum 先看题目要求：   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

Q:题目链接：ZigZag Conversion 先看题目要求： The string “PAYPALISHIRING” is written in a zigzag pattern on a given number of rows like this: (you may want to display this pattern in a fixed font for better le

Q:题目链接：Longest Common Prefix 先看题目要求：   Write a function to find the longest common prefix string amongst an array of strings. 有一个字符串数组，写一个函数找出最长的通用字符串前缀。比如输入[‘abc’,’abd’,’a’,’ac’]，输出’a’。分析   开始在想有没

Q:题目链接：Reverse Integer和Palindrome Number 先看题目要求：   Reverse Integer：   Palindrome Number： 分析  看完题目要求，大家估计就知道为什么把这两个题目放到一起了，都是有关回文数字的题目。题目都不难，主要注意下题目要求，第七题要求出参是32位整型，如果不是，返回0（这个在javascript中貌似没有多大意义
