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