Rust code to find palindrome string in rust

Hello,

As I said in the previous post that I have started learning Rust and made a simple fibonacci series generator. Today I made a palindrome string checker. it's very basic. I haven't used Enum or Struct in the code since I don't think it's necessary in this simple code.

here is the code:

    
use std::io;

fn main() {
    let mut input = String::new();
    let stdin = io::stdin();
    stdin.read_line(&mut input).unwrap(); // we want to exit in case it couldn't read from stdin

    input = input.replace("\n", ""); // Removing newline

    let mut is_palindrome: bool = true;
    for i in 0..input.len()/2 {
        let first_char: &str = &input[i..i+1];
        let last_char: &str = &input[input.len()-i-1..input.len()-i];
        if first_char != "\n" {
            if first_char != last_char {
                is_palindrome = false;
            }
        }
    }

    println!("palindrome: {}", is_palindrome);
}
