Problem Statement

Given are 1-digit positive integers a and b. Consider these two strings: the concatenation of b copies of the digit a, and the concatenation of a copies of the digit b. Which of these is lexicographically smaller?

Constraints

1 \leq a \leq 9

1 \leq b \leq 9

a and b are integers.

Input

Input is given from Standard Input in the following format:

a b

Output

Print the lexicographically smaller of the two strings. (If the two strings are equal, print one of them.)

Sample Input 1

4 3

Sample Output 1

3333

We have two strings 444 and 3333. Between them, 3333 is the lexicographically smaller.

Sample Input 2

7 7

Sample Output 2

7777777

import java.util.*;
 
public class Main {
 
    public static void main(String[] args) {
        Scanner stdIn = new Scanner(System.in);
        int a = stdIn.nextInt();        
        int b = stdIn.nextInt();        
        stdIn.close();

        if (a >= b){
            for (int i = 0; i < a; i++) {
                System.out.print(b);
            }
        } else {
            for (int i = 0; i < b; i++) {
                System.out.print(a);
            }
        }
    }
