LeetCode:至少是其他数字两倍的最大数[747] 题目描述 在一个给定的数组nums中,总是存在一个最大元素 . 查找数组中的最大元素是否至少是数组中每个其他数字的两倍. 如果是,则返回最大元素的索引,否则返回-1. 示例 1: 输入: nums = [3, 6, 1, 0] 输出: 1 解释: 6是最大的整数, 对于数组中的其他整数, 6大于数组中其他元素的两倍.6的索引是1, 所以我们返回1. 示例 2: 输入: nums = [1, 2, 3, 4] 输出: -1 解释: 4没有超过…
LeetCode 数组中重复的数字 题目描述 在一个长度为 n 的数组 nums 里的所有数字都在 0~n-1 的范围内.数组中某些数字是重复的,但不知道有几个数字重复了,也不知道每个数字重复了几次.请找出数组中任意一个重复的数字. 示例 1: 输入:[2,3,1,0,2,5,3] 输出:2或3 一得之见(Java/Python) 使用双循环,index 不等且 value 相等时,即重复. 时间复杂度 O(n²),空间复杂度 O(1) /** * 在一个长度为 n 的数组 nums 里的所有数…
SQL架构: Create table If Not Exists Logs (Id int, Num int) Truncate table Logs insert into Logs (Id, Num) values (') insert into Logs (Id, Num) values (') insert into Logs (Id, Num) values (') insert into Logs (Id, Num) values (') insert into Logs (Id,…
X is a good number if after rotating each digit individually by 180 degrees, we get a valid number that is different from X.  Each digit must be rotated - we cannot choose to leave it alone. A number is valid if each digit remains a digit after rotat…
Given an integer n, return 1 - n in lexicographical order. For example, given 13, return: [1,10,11,12,13,2,3,4,5,6,7,8,9]. Please optimize your algorithm to use less time and space. The input size may be as large as 5,000,000. 这道题给了我们一个整数n,让我们把区间[1,n…
Given an array containing n distinct numbers taken from 0, 1, 2, ..., n, find the one that is missing from the array. For example, Given nums = [0, 1, 3] return 2. Note: Your algorithm should run in linear runtime complexity. Could you implement it u…
