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.
파파고번역
정수 배열 번호가 지정되면 이 배열에서 세 번째 고유 최대 수를 반환합니다. 세 번째 최대값이 없으면 최대값을 반환합니다.
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.
