import java.util.Scanner;

public class Main {

            int quarters = 0;
            int dimes = 0;
            int nickels = 0;
            while (pennies >= 100) {
                pennies -= 100;
                dollars++;
            }
            while (pennies >= 25) {

                quarters++;
            }
            while (pennies >= 10) {

                dimes++;
            }
            while (pennies >= 5) {
                pennies -= 5;
                nickels++;
            }
            if (dollars > 0)
                System.out.println(dollars + " " + (dollars == 1 ? "Dollar" : "Dollars"));
            if (quarters > 0)
                System.out.println(quarters + " " + (quarters == 1 ? "Quarter" : "Quarters"));
            if (dimes > 0)
                System.out.println(dimes + " " + (dimes == 1 ? "Dime" : "Dimes"));
            if (nickels > 0)
                System.out.println(nickels + " " + (nickels == 1 ? "Nickel" : "Nickels"));
            if (pennies > 0)
                System.out.println(pennies + " " + (pennies == 1 ? "Penny" : "Pennies"));
        }
    }
