Golang : Fibonacci number generator examples



Tags : golang fibonacci

In mathematics, the Fibonacci numbers or Fibonacci sequence are the numbers in the following integer sequence.

1,1,2,3,5,8,13,21,34,55,89,144...

Here are some Fibonacci numbers generators examples.

Example 1 :

 package main

 import "fmt"

 func main() {
 for i, j := 0, 1; j < 100; i, j = i+j,i {
 fmt.Println(i)
 }
 }

Example 2:

 package main

 import (
  "fmt"
 )

 func fibonacci() chan int {
  in := make(chan int, 2)
  in <- 0
  in <- 1
  out := make(chan int)
  go func(in, out chan int) {
 for {
 a := <-in
 in <- <-in + a
 in <- a
 out <- a
 }
  }(in, out)
  return out
 }

 func main() {
  x := fibonacci()
  for i := 0; i < 10; i++ {
 fmt.Println(<-x)
  }
 }
