现在还有一个问题，在最后一个进程运行完之后，还会再打印一次输出

package main
import "fmt"
type Process struct { //定义进程的数据结构
    PRIORITY int
    CPUTIME int
    ALLTIME int
    STATE string
}
func main()  {
    PR := map[int]*Process{    //初始进程
        0: &Process{
            PRIORITY: 9,
            CPUTIME:  0,
            ALLTIME:  3,
            STATE:    "ready",
        },
        1: &Process{
            PRIORITY: 38,
            CPUTIME:  0,
            ALLTIME:  2,
            STATE:    "ready",
        },
        2: &Process{
            PRIORITY: 30,
            CPUTIME:  0,
            ALLTIME:  6,
            STATE:    "ready",
        },
        3: &Process{
            PRIORITY: 29,
            CPUTIME:  0,
            ALLTIME:  3,
            STATE:    "ready",
        },
        4: &Process{
            PRIORITY: 0,
            CPUTIME:  0,
            ALLTIME:  4,
            STATE:    "ready",
        },
    }
    for ; ;  {          //无限循环

    fmt.Println()

            flag = 1
        }else {
