### Instructions
|
||
|
|
|
||
|
|
Write a function `ThirdTimeIsACharm()` that takes a `string` as an argument and returns another `string` with every third character.
|
||
|
|
|
||
|
|
- Return the output followed by a newline `\n`.
|
||
|
|
- If the `string` is empty, return a newline `\n`.
|
||
|
|
- If there is no third character, return a newline `\n`.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func ThirdTimeIsACharm(str string) string {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"piscine"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Print(piscine.ThirdTimeIsACharm("123456789"))
|
||
|
|
fmt.Print(piscine.ThirdTimeIsACharm(""))
|
||
|
|
fmt.Print(piscine.ThirdTimeIsACharm("a b c d e f"))
|
||
|
|
fmt.Print(piscine.ThirdTimeIsACharm("12"))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run . | cat -e
|
||
|
|
369$
|
||
|
|
$
|
||
|
|
b e$
|
||
|
|
$
|
||
|
|
```
