## smallest
|
||
|
|
||
|
### Instructions
|
||
|
|
||
|
Create a function named `smallest` that gets the smallest positive number in the `HashMap`.
|
||
|
|
||
|
### Expected Function
|
||
|
|
||
|
```rust
|
||
|
pub fn smallest(h: HashMap<&str, i32>) -> i32 {
|
||
|
}
|
||
|
```
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
Here is a program to test your function.
|
||
|
|
||
|
```rust
|
||
|
use std::collections::HashMap;
|
||
|
use smallest::smallest;
|
||
|
|
||
|
fn main() {
|
||
|
|
||
|
let mut hash = HashMap::new();
|
||
|
hash.insert("Cat", 122);
|
||
|
hash.insert("Dog", 333);
|
||
|
hash.insert("Elephant", 334);
|
||
|
hash.insert("Gorilla", 14);
|
||
|
|
||
|
println!("The smallest of the elements in the HashMap is {}", smallest(hash));
|
||
|
}
|
||
|
```
|
||
|
|
||
|
And its output
|
||
|
|
||
|
```console
|
||
|
$ cargo run
|
||
|
The smallest of the elements in the HashMap is 14
|
||
|
$
|
||
|
```
|
||
|
|
||
|
