smallest
Instructions
Create a function named smallest
that gets the smallest number in the HashMap
.
If the HashMap
is empty, return the maximum i32
.
Expected Function
pub fn smallest(h: HashMap<&str, i32>) -> i32 {
}
Usage
Here is a program to test your function.
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
$ cargo run
The smallest of the elements in the HashMap is 14
$
