golang 两个协成交替打印1-100的奇数偶数
  1. package main
  2. import (
  3.     "fmt"
  4.     "time"
  5. )
  6. var POOL = 100
  7. func groutine1(p chan int) {
  8.     for i := 1; i <= POOL; i++ {
  9.         p <- i
  10.         if i%2 == 1 {
  11.             fmt.Println("groutine-1:", i)
  12.         }
  13.     }
  14. }
  15. func groutine2(p chan int) {
  16.     for i := 1; i <= POOL; i++ {
  17.         <-p
  18.         if i%2 == 0 {
  19.             fmt.Println("groutine-2:", i)
