rot21

Instructions

The purpose of this exercise is to create a rot21 function that works like the ROT13 cipher.

This function will receive a string and it will rotate each letter of that string 21 times to the right.

The function should only rotate letters. If the string includes punctuation, symbols and/or numbers they will remain the same.

Expected functions

pub fn rot21(input: &str) -> String {

}

Usage

Here is a program to test your function.

use rot21::rot21;

fn main() {
    println!("The letter \"a\" becomes: {}", rot21("a"));
    println!("The letter \"m\" becomes: {}", rot21("m"));
    println!("The word \"MISS\" becomes: {}", rot21("MISS"));
    println!("Your cypher wil be: {}", rot21("Testing numbers 1 2 3"));
    println!("Your cypher wil be: {}", rot21("rot21 works!"));
}

And its output:

student@ubuntu:~/[[ROOT]]/test$ cargo run
The letter "a" becomes: v
The letter "m" becomes: h
The word "MISS" becomes: HDNN
Your cypher wil be: Oznodib iphwzmn 1 2 3
Your cypher wil be: mjo21 rjmfn!
