414 - Third Maximum Number.
Easy

Given an integer array nums, return the third distinct maximum number in this array. If the third maximum does not exist, return the maximum number.

Example 1:

Input: nums = [3,2,1]

Output: 1

Explanation: The first distinct maximum is 3. The second distinct maximum is 2. The third distinct maximum is 1.

Example 2:

Input: nums = [1,2]

Output: 2

Explanation: The first distinct maximum is 2. The second distinct maximum is 1. The third distinct maximum does not exist, so the maximum (2) is returned instead.

Example 3:

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

Output: 1

Explanation: The first distinct maximum is 3. The second distinct maximum is 2 (both 2’s are counted together since they have the same value). The third distinct maximum is 1.

Constraints:
- 1 <= nums.length <= 10⁴
- -2³¹ <= nums[i] <= 2³¹ - 1
