Missing Number in Array
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*.
Examples & Test Cases
Example 1:
Input: 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: 0 1
Output: 2
Example 3:
Input: 9 6 4 2 3 5 7 0 1
Output: 8
Constraints:
• n == nums.length
• 1 <= n <= 10^4
• 0 <= nums[i] <= n
• All the numbers of nums are unique.
