golang两个协程交替打印1-100的奇数偶数

代码如下

package main

import (
    "fmt"
    "time"
)

var POOL = 100

func groutine1(p chan int) {

    for i := 1; i <= POOL; i++ {
        p <- i
        if i%2 == 1 {
            fmt.Println("groutine-1:", i)
        }
    }
}

func groutine2(p chan int) {

    for i := 1; i <= POOL; i++ {
        <-p
        if i%2 == 0 {
            fmt.Println("groutine-2:", i)
        }
    }
}

func main() {
    msg := make(chan int)

    go groutine1(msg)
    go groutine2(msg)

    time.Sleep(time.Second * 1)

}
