题解：

var desc = [3]string{"Gold Medal", "Silver Medal", "Bronze Medal"}

func findRelativeRanks(score []int) []string {
    n := len(score)
    type pair struct{ score, idx int }
    arr := make([]pair, n)
    for i, s := range score {
        arr[i] = pair{s, i}
    }
    sort.Slice(arr, func(i, j int) bool { return arr[i].score > arr[j].score })

    ans := make([]string, n)
    for i, p := range arr {
        if i < 3 {
            ans[p.idx] = desc[i]
        } else {
            ans[p.idx] = strconv.Itoa(i + 1)
        }
    }
    return ans
}
