name_initials

Instructions

Create a function named initials. This function will receive a vector of string literals with names, and return a vector of Strings with the initials of each name.

Expected Functions

pub fn initials(names: Vec<&str>) -> Vec<String> {
}

Your heap allocations will be monitored to ensure that you do not make too many allocations, and that your allocations are reasonably sized.

Usage

Here is a program to test your function:

use name_initials::initials;

fn main() {
    let names = vec!["Harry Potter", "Someone Else", "J. L.", "Barack Obama"];
    println!("{:?}", initials(names));
}

And its output

$ cargo run
["H. P.", "S. E.", "J. L.", "B. O."]
$
