Input: nums = [1,2,3,3]

Output: 3

Example 2:

Input: nums = [2,1,2,5,3,2]

Output: 2

Example 3:

Input: nums = [5,1,5,2,5,3,5,4]

Output: 5

Constraints:

• 2 <= n <= 5000
• nums.length == 2 * n
• 0 <= nums[i] <= 104
• nums contains n + 1 unique elements and one of them is repeated exactly n times.
