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

using System;
using System.Linq;
class Program
{
    static void Main(string[] args)
    {
        var input = Console.ReadLine().Split(' ').ToArray();
        string a = input[0];
        string b = input[1];
        bool useA = a.CompareTo(b) < 0;
        
        if (useA)
        {
            for (int i = 0; i < int.Parse(b); i++)
            {
                Console.Write(a);
            }
        }
        else
        {
            for (int i = 0; i < int.Parse(a); i++)
            {
                Console.Write(b);
            }
        }
        Console.WriteLine();
    }
