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 (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>

int	main(void)
{
  	int	a;
  	int	b;
  	int	num;
  	int	i;
  
  	num = scanf("%d %d", &a, &b);
  	if (num != 2)
      	return (0);
  
  	if (a < b)
    {
      	for(i=0; i<b; i++)
        {
          	printf("%d", a);
        }
    }
  	else
    {
      	for(i=0; i<a; i++)
        {
          	printf("%d", b);
        }
    }
  	return (0);
}
