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
}
