### Intructions
Write a function that returns `true` if the `int` passed as parameter is a prime number. Otherwise it returns `false`.

### Usage
Here is a possible [program](TODO-LINK) to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func main() {
fmt.Println(piscine.IsPrime(5))
fmt.Println(piscine.IsPrime(4))
}
```
And its output :
```console
student@ubuntu:~/piscine/test$ go build
student@ubuntu:~/piscine/test$ ./test
true
false
student@ubuntu:~/piscine/test$
```
