Given an array nums of n integers where nums[i] is in the range [1, n], return an array of all the integers in the range [1, n] that do not appear in nums.

\n\n

 

\n

Example 1:

\n
Input: nums = [4,3,2,7,8,2,3,1]\nOutput: [5,6]\n

Example 2:

\n
Input: nums = [1,1]\nOutput: [2]\n
\n

Constraints:

\n\n\n\n

 

\n

Follow up: Could you do it without extra space and in O(n) runtime? You may assume the returned list does not count as extra space.

\n", "translatedTitle": "找到所有数组中消失的数字", "translatedContent": "

给你一个含 n 个整数的数组 nums ，其中 nums[i] 在区间 [1, n] 内。请你找出所有在 [1, n] 范围内但没有出现在 nums 中的数字，并以数组的形式返回结果。

\n\n

 

\n\n

示例 1：

\n\n
\n输入：nums = [4,3,2,7,8,2,3,1]\n输出：[5,6]\n
\n\n

示例 2：

\n\n
\n输入：nums = [1,1]\n输出：[2]\n
\n\n

进阶：你能在不使用额外空间且时间复杂度为 O(n) 的情况下解决这个问题吗? 你可以假定返回的数组不算在额外空间内。
