Java realization

import java.util.*;

class Main

{

public static void main(String[] args)

{

Scanner con = new Scanner(System.in);

Read the input value of n.

int n = con.nextInt();

Print the numbered text “OK” n times.

for(int i = 1; i <= n; i++)

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

con.close();

}

}

Python realization

Read the input value of n.

n = int(input())

Print the numbered text “OK” n times.

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

print(i,"OK")
