寫斐波那契數列其實很簡單

但是我們用channel來寫

自我鍛鍊一下

也熟悉一下channel的用法

func main() {

   channel := make(chan int)
   quit := make(chan bool)

   go func() {

      for i := 0; i < 100; i++ {
         num := <-channel
         fmt.Println("num是", num)
      }

      quit <- true

   }()

   fibonacci(channel, quit)

}

func fibonacci(channel chan int, quit chan bool) {
   x, y := 1, 1
   for {
      select {
      case channel <- x:
         x, y = y, x+y
      case <-quit:
         fmt.Println("結束")
         return
      }
   }
}
