太颠覆我对golang的认知了，调试时明明有值，但打印出来就是零，要崩溃了

``` go func Rem(a []string) (ret []string) { now:=time.Now() sort.Strings(a) finish:=time.Since(now) fmt.Println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!") sss:=strconv.FormatInt(int64(finish),10) fmt.Printf("%s",sss) fmt.Println("sss:"+sss) aaa:=int64(finish) fmt.Println(aaa) fmt.Println(int64(finish)) fmt.Println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!") return ret } ``` sss和aaa打印出来就是零，但是调试的时候sss和aaa明明就是有值的啊
