fn is_rotation(s1: &str, s2: &str) -> bool {
    s1.len() == s2.len() && (s1.to_owned() + s1).contains(s2)
}

fn main() {
    let s1 = "abbc";
    let s2 = "cabb";
    
    println!("{}", if is_rotation(s1, s2) { "yes" } else { "no" });

    let s1 = "abbc";
    let s2 = "bbac";
    
    println!("{}", if is_rotation(s1, s2) { "yes" } else { "no" });
}

yes
no
