|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Write a function, CollatzCountdown, that returns the number of steps to reach 1 using the collatz countdown.
|
||
|
|
|
||
|
|
The function must have the following signature.
|
||
|
|
|
||
|
|
## Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func CollatzCountdown(start int) int {
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
student ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
steps := student.CollatzCountdown(12)
|
||
|
|
fmt.Println(steps)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/student/collatzcountdown$ go build
|
||
|
|
student@ubuntu:~/student/collatzcountdown$ ./collatzcountdown
|
||
|
|
10
|
||
|
|
student@ubuntu:~/student/collatzcountdown$
|
||
|
|
```
