### Instructions

There was a vote. There are people who voted positively, negatively, and randomly. 
Figure out if the final answer depends on random people or not.
If it does print '?'

Write a function, `Nauuo`, that returns final result of voting.

### Expected function

```go
func Nauuo(plus, minus, rand int) string {

}
```

### Usage

Here is a possible program to test your function :

```go
package main

import (
	"fmt"
	piscine ".."
)

func main() {
	fmt.Println(piscine.Nauuo(50, 43, 20))
	fmt.Println(piscine.Nauuo(13, 13, 0))
	fmt.Println(piscine.Nauuo(10, 9, 0))
	fmt.Println(piscine.Nauuo(5, 9, 2))
}
```

And its output :

```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
?
0
+
-
student@ubuntu:~/[[ROOT]]/test$
```
