## jumpover

### Instructions

Write a function `JumpOver()` that takes a `string` and returns another `string` with every third character.

- Prints the output followed by newline `\n`.
- If the `string` is empty, return newline `\n`.
- If there is no third character, return newline `\n`.

### Expected function

```go
func JumpOver(str string) string {

}
```

### Usage

Here is a possible program to test your function:

```go
package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Print(piscine.JumpOver("1010101010"))
	fmt.Print(piscine.JumpOver(""))
	fmt.Print(piscine.JumpOver("t w e l v e"))
	fmt.Print(piscine.JumpOver("12"))
}
```

And its output:

```go
$ go run . | cat -e
101$
$
w v$
$
```
