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 sc =  new Scanner(System.in);
		int a = sc.nextInt();
		int b = sc.nextInt();
		String str1="";
		if(a<b){
			for(int i = 0;i<b;i++)
			str1+=""+a;
		}else{
			for(int i = 0;i<a;i++)
			str1 += ""+b;
		}
		System.out.println(str1);
		
	}
