go 实现两个协程交替打印1-100的奇偶数

func main() {
    var c = make(chan struct{})
    go func() {
        for i := 1; i <= 100; i++ {
            c<- struct{}{}
            if i%2 == 0 {
                fmt.Println(i)
            }
        }
    }()
    go func() {
        for i := 1; i <= 100; i++ {
            <-c
            if i%2 != 0 {
                fmt.Println(i)
            }
        }
    }()
    select {}
}
