如何使用Golang统计地图中某个值出现的次数？

package main

import "fmt"

func countOccurrences(m map[string]int, value string) int {
    count := 0
    for _, v := range m {
        if v == value {
            count++
        }
    }
    return count
}

func main() {
    // 创建一个地图，并初始化一些数据
    m := map[string]int{
        "a": 1,
        "b": 2,
        "c": 1,
        "d": 3,
        "e": 1,
    }

    // 统计地图中值为1的出现次数
    value := "1"
    occurrences := countOccurrences(m, value)
    fmt.Printf("%s出现的次数为：%d\n", value, occurrences)
}
