268 - Missing Number\. Easy Given an array `nums` containing `n` distinct numbers in the range `[0, n]`, return _the only number in the range that is missing from the array._ **Example 1:** **Input:** nums = [3,0,1] **Output:** 2 **Explanation:** n = 3 since there are 3 numbers, so all numbers are in the range [0,3]. 2 is the missing number in the range since it does not appear in nums. **Example 2:** **Input:** nums = [0,1] **Output:** 2 **Explanation:** n = 2 since there are 2 numbers, so all numbers are in the range [0,2]. 2 is the missing number in the range since it does not appear in nums. **Example 3:** **Input:** nums = [9,6,4,2,3,5,7,0,1] **Output:** 8 **Explanation:** n = 9 since there are 9 numbers, so all numbers are in the range [0,9]. 8 is the missing number in the range since it does not appear in nums. **Example 4:** **Input:** nums = [0] **Output:** 1 **Explanation:** n = 1 since there is 1 number, so all numbers are in the range [0,1]. 1 is the missing number in the range since it does not appear in nums. **Constraints:** * `n == nums.length` * 1 <= n <= 104 * `0 <= nums[i] <= n` * All the numbers of `nums` are **unique**. **Follow up:** Could you implement a solution using only `O(1)` extra space complexity and `O(n)` runtime complexity?
