	`6`	`+ Output: ["Gold Medal", "Silver Medal", "Bronze Medal", "4", "5"]`
	`7`	`+ Explanation: The first three athletes got the top three highest scores, so they got "Gold Medal", "Silver Medal" and "Bronze Medal".`
	`8`	`+ For the left two athletes, you just need to output their relative ranks according to their scores.`
	`9`	`+ Note:`
	`10`	`+ N is a positive integer and won't exceed 10,000.`
