## min_and_max
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a **function** named `min_and_max` that receives three `i32` and returns a `tuple` with the minimum and the maximum number received as input.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
pub fn min_and_max(nb_1: i32, nb_2: i32, nb_3: i32) -> (i32, i32) {
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a program to test your function
|
||
|
|
|
||
|
|
```rust
|
||
|
|
use min_and_max::min_and_max;
|
||
|
|
|
||
|
|
fn main() {
|
||
|
|
let nb_1 = 9;
|
||
|
|
let nb_2 = 4;
|
||
|
|
let nb_3 = 2;
|
||
|
|
let (min, max) = min_and_max(nb_1, nb_2, nb_3);
|
||
|
|
println!(
|
||
|
|
"The minimum is {}, the maximum is {}",
|
||
|
|
min, max
|
||
|
|
);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ cargo run
|
||
|
|
The minimum is 2, the maximum is 9
|
||
|
|
$
|
||
|
|
```
|
||
|
|
|
||
|
