Write a Rust program to check if a given string is a valid palindrome.

Question

Sure, here is a Rust program to check if a given string is a valid palindrome:

Rust

fn is_palindrome(string: &str) -> bool {
    let mut reversed_string = String::new();
    for c in string.chars().rev() {
        reversed_string.push(c);
    }
    return string == reversed_string;
}

fn main() {
    let string = "racecar";
    let is_palindrome = is_palindrome(string);
    println!("The string {} is {}a palindrome", string, if is_palindrome { "" } else { "not "));
}

This program first defines a function called is_palindrome that takes a string as input and returns a bool value. The function first creates a new string called reversed_string. Then, the function iterates through the string string, adding each character to the reversed_string in reverse order. Finally, the function compares the string and reversed_string and returns true if they are equal. Otherwise, the function returns false.

The main function of the program then calls the is_palindrome function with the string "racecar" as input. The result of the function call is then printed to the console.

To run the program, you can save it as a file called is_palindrome.rs and then compile it using the following command:

Code snippet

rustc is_palindrome.rs

Once the program is compiled, you can run it using the following command:

Code snippet

./is_palindrome

This will print the following output to the console:

Code snippet

The string racecar is a palindrome
