LeetCode 用户最喜欢的100题 | 面试最容易被问到的题

LeetCode 指南 === - 语言: Java - 说明： 每道题在代码头部都添加了我的解题思路和批注，Eg: /***** * 287. Find the Duplicate Number * 题意：n+1个数属于[1~n]，找出重复的那个数 * 难度：Medium * 分类：Array, Two Pointers, Binary Search * 思路：如果nums[i]不在对应位置，则和对应位置交换。如果对应位置上也为该数，说明这个数就是重复的数字。这个方法改变了数组。是错误的。 * 另一种方法，把问题转换成有环链表，找环的起始节点。O(n) O(1) lc142 * 二分查找，每次看一边数字的个数, O(nlog(n)) O(1) * Tips：剑指offer原题 */ --- ### RoadMap - :soccer: [用户最喜欢的100道题(Top 100 Liked Questions)](./Top100.md) - :basketball:
