Given a list of words and a dictionary of letter scores, find the word with the highest score

main.rs

fn main() {
    let highest = vec!["apple", "banana", "cherry", "date", "fig"]
        .into_iter()
        .map(|w| (w, score(w.to_owned())))
        .reduce(|acc, b| {
            if b.1 > acc.1 {
                return b;
            }
            acc
        })
        .unwrap();
    println!("{}: {}", highest.0, highest.1);
}

fn score(word: String) -> u32 {
    word.chars()
        .into_iter()
        .map(|c| c.to_ascii_lowercase() as u32 - 96)
        .sum::<u32>()
        * word.len() as u32
}
