How to check if two strings have the same number of words in Rust

Answer 1

fn count_words(s: &str) -> usize {
    s.split_whitespace().count()
}

fn main() {
    let string1 = "c c++ pascal java c#".to_string();
    let string2 = "go rust php javascript swift".to_string();

    let words1 = count_words(&string1);
    let words2 = count_words(&string2);

    if words1 == words2 {
        println!("Both strings have the same number of words.");
    } else {
        println!("The strings have a different number of words.");
    }
}


      
/*

Both strings have the same number of words.
