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) throws Exception {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        String b = sc.next();
        int inta = Integer.parseInt(a);
        int intb = Integer.parseInt(b);
        
        if(inta <= intb) {
            for(int i = 0; i < intb; i++) {
                System.out.print(a);
            }
            System.out.println("");
        }else {
            for(int i = 0; i < inta; i++) {
                System.out.print(b);
            }
            System.out.println("");
        }
        
        }
