import java.io.*;

import java.util.Scanner;

public class Main {

// class declaration
public static String repeat(String str,int n)
{
if (n==1)
return str;
else
return str+repeat(str,(n-1));
}
public static void main(String args[]){

System.out.println("please enter the string and number of times");

Scanner sc= new Scanner(System.in);
String str;

int n;
str= sc.next();

n=sc.nextInt();

System.out.println("result : " +repeat(str,n)); // print the result
}
}

INPUT ----> String mon n=4

result : monmonmonmon
