golang两个协程交替打印1-100的奇数偶数 GOLANG

代码如下

package mainimport ( "fmt" "time" )var POOL = 100func 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)}

测试结果

groutine-1: 1 groutine-2: 2 groutine-1: 3 groutine-2: 4 groutine-1: 5 groutine-2: 6 groutine-1: 7 groutine-2: 8 groutine-1: 9 groutine-2: 10 groutine-1: 11 groutine-2: 12 groutine-1: 13 groutine-2: 14 groutine-1: 15 groutine-2: 16 groutine-1: 17 groutine-2: 18 groutine-1: 19 groutine-2: 20 groutine-1: 21 groutine-2: 22 groutine-1: 23 groutine-2: 24 groutine-1: 25 groutine-2: 26 groutine-1: 27 groutine-2: 28 groutine-1: 29 groutine-2: 30 groutine-1: 31 groutine-2: 32 groutine-1: 33 groutine-2: 34 groutine-1: 35 groutine-2: 36 groutine-1: 37 groutine-2: 38 groutine-1: 39 groutine-2: 40 groutine-1: 41 groutine-2: 42 groutine-1: 43 groutine-2: 44 groutine-1: 45 groutine-2: 46 groutine-1: 47 groutine-2: 48 groutine-1: 49 groutine-2: 50 groutine-1: 51 groutine-2: 52 groutine-1: 53 groutine-2: 54 groutine-1: 55 groutine-2: 56 groutine-1: 57 groutine-2: 58 groutine-1: 59 groutine-2: 60 groutine-1: 61 groutine-2: 62 groutine-1: 63 groutine-2: 64 groutine-1: 65 groutine-2: 66 groutine-1: 67 groutine-2: 68 groutine-1: 69 groutine-2: 70 groutine-1: 71 groutine-2: 72 groutine-1: 73 groutine-2: 74 groutine-1: 75 groutine-2: 76 groutine-1: 77 groutine-2: 78 groutine-1: 79 groutine-2: 80 groutine-1: 81 groutine-2: 82 groutine-1: 83 groutine-2: 84 groutine-1: 85 groutine-2: 86 groutine-1: 87 groutine-2: 88 groutine-1: 89 groutine-2: 90 groutine-1: 91 groutine-2: 92 groutine-1: 93 groutine-2: 94 groutine-1: 95 groutine-2: 96 groutine-1: 97 groutine-2: 98 groutine-1: 99 groutine-2: 100
