go语言输入二维数组

func main(){
    var n,m,tmp int
    fmt.Scanf("%v %v",&n,&m)
    way:=make([][]int,0,n)
    for i:=0;i{
        args:=make([]int,0,m)
        for j:=0;j{
            fmt.Scanf("%v",&tmp)
            args=append(args,tmp)
        }
        way=append(way,args)
    }

    fmt.Println("way",way)
}
