A valid program in nano rust

fn factorial(x) {
    // Conditionals are supported!
    if x == 0 {
        1
    } else {
        x * factorial(x - 1)
    }
}

// The main function
fn main() {
    let three = 3;
    let meaning_of_life = three * 14 + 1;

    print("Hello, world!");
    print("The meaning of life is...");

    if meaning_of_life == 42 {
        print(meaning_of_life);
    } else {
        print("...something we cannot know");

        print("However, I can tell you that the factorial of 10 is...");
        // Function calling
        print(factorial(10));
    }
}
