Missing Number 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…

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 usi…

Given an array containing n distinct numbers taken from 0, 1, 2, ..., n, find the one that is missing from the array. Example 1 Input: [3,0,1] Output: 2 Example 2 Input: [9,6,4,2,3,5,7,0,1] Output: 8 Note:Your algorithm should run in linear runtime c…

268. 缺失数字 给定一个包含 0, 1, 2, -, n 中 n 个数的序列,找出 0 - n 中没有出现在序列中的那个数. 示例 1: 输入: [3,0,1] 输出: 2 示例 2: 输入: [9,6,4,2,3,5,7,0,1] 输出: 8 说明: 你的算法应具有线性时间复杂度.你能否仅使用额外常数空间来实现? PS:位运算 class Solution { public int missingNumber(int[] nums) { int res = nums.length; for…

给定一个包含 0, 1, 2, ..., n 中 n 个数的序列,找出 0 .. n 中没有出现在序列中的那个数. 示例 1: 输入: [3,0,1] 输出: 2 示例 2: 输入: [9,6,4,2,3,5,7,0,1] 输出: 8 说明: 你的算法应具有线性时间复杂度.你能否仅使用额外常数空间来实现? 思路 因为给定的序列也是从0开始,所以可以进行排序,比较索引和索引对应的值,如果两个不等于说明就确实一个值了,还要注意一个情况是,没出现的数字是n 代码 class Solution(obje…
