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: Wrong Answer)

using System;
using System.Linq;

class Program {
  public static void Main() {
    int[] input = Console.ReadLine().Split(' ').Select(i => int.Parse(i)).ToArray();
    int a, b;
    
    if (input[0] == input[1]) {
      a = input[0];
      b = input[0];
    } else if (input[0] > input[1]) {
      a = input[0];
      b = input[1];
    } else {
      a = input[1];
      b = input[0];
    }
  
    for (int i = 0; i < b; i++)
      Console.Write(a);
  }
