golang 根据分数计算排名,同分数排名相同

package main

import (
    "fmt"
    "sort"
)

type userInfo struct {
    Uid   int64 \/\/uid
    Score int64 \/\/分数
    Rank  int   \/\/排名
}

type Score []userInfo

func (s Score) Len() int      { return len(s) }
func (s Score) Swap(i, j int) { s[i], s[j] = s[j], s[i] }
func (s Score) Less(i, j int) bool { return s[i].Score > s[j].Score } \/\/ 从大到小排序

func main()  {
    users := []userInfo{}
    scores := []int64{0, 2, 2, 3, 0, 0, 0, 0, 0, 0,0}
    fmt.Println(scores)
    for i := 1; i <= 10; i++ {
        users = append(users, userInfo{
            Uid:   int64(i),
            Score: scores[i],
        })
    }

    sort.Sort(Score(users))
    fmt.Printf("%+v \n
