import java.util.Scanner;
public class Denominations2 {
    public static void main(String args[]){
        double amt;
        int amount;
        int q = 0, d = 0, n = 0, c = 0;
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter a dollar amount: ");
        amt = scanner.nextDouble();
        amount = (int)(amt*100);
        if (amount >= 25) {
            q = amount/25;
            amount = amount % 25;
        }
        if(q == 1){
            System.out.println("1 quarter");
        }
        else{
            System.out.println(q+" quarters");
        }
        if (amount >= 10) {
            d = amount/10;
            amount = amount % 10;
        }
        if(d == 1){
            System.out.println("1 dime");
        }
        else{
            System.out.println(d+" dimes");
        }
        if (amount >= 5) {
            n = amount/5;
            amount = amount % 5;
        }
        if(n == 1){
            System.out.println("1 nickel");
        }
        else{
            System.out.println(n+" nickels");
        }
        if(amount == 1){
            System.out.println("1 cent");
        }
        else{
            System.out.println(amount+" cents");
        }
    }
