slices_to_map

Instructions:

Create a function that borrows two slices and returns a hashmap where the first slice represents the keys and the second represents the values.

• If the slices have different sizes, the function should return the hashmap with the size of the smallest list.

Expected Function

pub fn slices_to_map(&[T], &[U]) -> HashMap<&T, &U> {

}

Usage

Here is a program to test your function.

use slices_to_map::*;

fn main() {
	let keys = ["Olivia", "Liam", "Emma", "Noah", "James"];
	let values = [1, 3, 23, 5, 2];
	println!("{:?}", slices_to_map(&keys, &values));
}

And its output

$ cargo run
{"James": 2, "Liam": 3, "Emma": 23, "Noah": 5, "Olivia": 1}
$
