fn generateFloydTriangle(rows : i32) {        
    let mut  number = 1;
    {
        let mut  i = 1;
        while i <= rows {
            {
                let mut  j = 1;
                while j <= i {
                    print!("{} ", number.to_string());
                    number += 1;
                    j += 1;
                }
            }
            println!("");
            i += 1;

fn main() {
    generateFloydTriangle(6);
