645 - Set Mismatch\. Easy You have a set of integers `s`, which originally contains all the numbers from `1` to `n`. Unfortunately, due to some error, one of the numbers in `s` got duplicated to another number in the set, which results in **repetition of one** number and **loss of another** number. You are given an integer array `nums` representing the data status of this set after the error. Find the number that occurs twice and the number that is missing and return _them in the form of an array_. **Example 1:** **Input:** nums = [1,2,2,4] **Output:** [2,3] **Example 2:** **Input:** nums = [1,1] **Output:** [1,2] **Constraints:** * 2 <= nums.length <= 10⁴ * 1 <= nums[i] <= 10⁴
