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

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

class Program
{
	static void Main(string[] args)
	{
		// 整数の入力
		string[] input = Console.ReadLine().Split(' ');
		int a = int.Parse(input[0]);
		int b = int.Parse(input[1]);
		// スペース区切りの整数の入力

		// 文字列の入力
		//出力
		if (a>b)
		{
			for (int i = 0; i < a; i++)
			{
				Console.Write(b);

			}
		}
		else
		{
			for (int i = 0; i < b; i++)
			{
				Console.Write(a);

			}
		}
	}
