启动两个线程, 一个输出 1,3,5,7…99, 另一个输出 2,4,6,8…100 最后 STDOUT 中按序输出 1,2,3,4,5…100

package main

import (
	"fmt"
	"time"
)

var pool = 100

//奇数
func oddNum(c chan int) {
	for i := 1; i <= pool; i++ {
		c <- i
		if i%2 == 1 {
			fmt.Println(i)
		}
	}
}

//偶数
func even(c chan int) {
	for i := 1; i <= pool; i++ {
		<-c
		if i%2 == 0 {
			fmt.Println(i)
		}
	}
}

func main() {

	c := make(chan int)

	go oddNum(c)
	go even(c)

	time.Sleep(time.Second * 1)

}
