{ "data": { "question": { "questionId": "414", "questionFrontendId": "414", "boundTopicId": null, "title": "Third Maximum Number", "titleSlug": "third-maximum-number", "content": "

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.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [3,2,1]\nOutput: 1\nExplanation:\nThe first distinct maximum is 3.\nThe second distinct maximum is 2.\nThe third distinct maximum is 1.\n
\n\n

Example 2:

\n\n
\nInput: nums = [1,2]\nOutput: 2\nExplanation:\nThe first distinct maximum is 2.\nThe second distinct maximum is 1.\nThe third distinct maximum does not exist, so the maximum (2) is returned instead.\n
\n\n

Example 3:

\n\n
\nInput: nums = [2,2,3,1]\nOutput: 1\nExplanation:\nThe first distinct maximum is 3.\nThe second distinct maximum is 2 (both 2's are counted together since they have the same value).\nThe third distinct maximum is 1.\n
