[SOLVED] Print something when second loop occured

Question

println!("guess number between 1 - 20");
println!("Please input your guess");
loop {
println!("Try again..");
let mut user_guessed = String::new();
io::stdin()
.read_line(&mut user_guessed)
.expect("your input guessed wasn't a valid number!");
let user_guessed: u32 = match user_guessed.trim().parse() {
Ok(u32) => u32,
Err(_) => {
