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

#include <stdio.h>

#include <math.h>
int main()
{
	int i,j,k;
	scanf("%d %d",&i,&j);
	if(i<j)
	{
		i=i+j;
		j=i-j;
		i=i-j;
	}
	for(k=0;k<i;k++)
	printf("%d",j);
	return 0;
