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
