golang中的错误fatal error: concurrent map writes

具体的代码如下：
package main

import (
"fmt"
"time"
)

var m = make(map[int]int, 10)

func solution(n int){
res := 1
for i:=1; i<=n; i++{ res = res * i } m[n] = res } func main(){ for i:=1; i<=200; i++{ go solution(i) } time.Sleep(time.Second*10) for ind, val := range m{ fmt.Printf("[%d] = %d /n", ind, val) } } 出现如下的错误： fatal error: concurrent map writes fatal error: concurrent map writes

golang中的错误fatal error: concurrent map writes最先出现在Python成神之路。
