LeetCode | 506. Relative Ranks

Givenscores of N athletes, find their relative ranks and the people with thetop three highest scores, who will be awarded medals: "Gold Medal","Silver Medal" and "Bronze Medal".

Example1:

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

Output: ["Gold Medal", "SilverMedal", "Bronze Medal", "4", "5"]

Explanation: The first three athletes got the topthree highest scores, so they got "Gold Medal", "SilverMedal" and "Bronze Medal".
For the left two athletes, you just need to output their relative ranksaccording to their scores.

Note:

1.      N is a positive integer and won'texceed 10,000.

2.      All the scores of athletes areguaranteed to be unique.

简单题，先把原数组按照其分数从高到低排序（注意是按照分数从高到低排序），然后按照其排序完成之后的顺序修改其对应位置上的string标志就好了，

class Solution {
public:
    static bool cmp(pair<int, int> &a, pair<int, int> &b)
{
	return a.second > b.second;
}
vector<string> findRelativeRanks(vector<int>& nums) {
	int n = nums.size();
	vector<string> result(n,"");
	vector<pair<int, int>> temp;
	for (int i = 0; i < n; i++)
	{
		temp.push_back(pair<int, int>(i, nums[i]));
	}
	sort(temp.begin(), temp.end(),cmp);
	if (n >= 1) result[temp[0].first] = "Gold Medal";
	if (n >= 2) result[temp[1].first] = "Silver Medal";
	if (n >= 3) result[temp[2].first] = "Bronze Medal";
	for (int i = 4; i <= n; i++)
	{
		result[temp[i - 1].first] = to_string(i);
	}
	return result;
}
};
