reverse_it

Instructions

Create a function called reverse_it that takes a number and returns a string with the number backwards followed by the original number. If the number is negative you should just add the char - to the beginning of the string.

Expected Functions

fn reverse_it(v: i32) -> String {}

Usage

Here is a program to test your function

fn main() {
    println!("{}", reverse_it(123));
    println!("{}", reverse_it(-123));
}

And its output

student@ubuntu:~/[[ROOT]]/test$ cargo run
321123
