Golang : Fibonacci number generator examples
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)
}
}
