Instructions

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

This exercise will test how many times the heap is going to be allocated!
So try your best to allocate the minimum data on the heap!

Notions

• stack and heap

Expected Function

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

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."]
$
