use itertools::Itertools;

fn main() {
    let words = vec!["Rust", "Programming", "Language"];
    
    let permutations = words.iter().permutations(words.len());

    for perm in permutations {
        println!("{:?}", perm);
        println!("{:?}, {:?}, {:?}", perm[0], perm[1], perm[2]);
    }
}
