8933. Timer

A positive integer n is given. Simulate a countdown timer from n to 0 seconds as shown in the example.

Input. One positive integer n.

Output. Print all integers from n to 0 inclusive with the text “sek” in a column.

Sample input	Sample output
2	2 sek 1 sek 0 sek

SOLUTION

loop

Algorithm analysis

Use a for loop. Print all integers from n to 0 in descending order with the text “sek” in a column.

Algorithm realization

Read the input data.

scanf("%d", &n);

Print the numbers from n to 0 in descending order with the text “sek” in a column.

for (i = n; i >= 0; i--)

printf("%d sek\n", i);

Java realization

import java.util.*;

class Main

{

public static void main(String[] args)

{

Scanner con = new Scanner(System.in);

int n = con.nextInt();

for(int i = n; i >= 0; i--)

System.out.println(i + " sek");

con.close();

}

}

Python realization

Read the input data.

n = int(input())

Print the numbers from n to 0 in descending order with the text “sek” in a column.

for i in range(n, -1, -1):

print(i, "sek")
