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: Wrong Answer)

#include <stdio.h>
#include <string.h>
int main(void)
{
	int a, b;
	scanf("%d %d", &a, &b);
	char A[10], B[10];
	int i;
	for (i = 0; i < a; i++)
	{
		A[i] = a + '0';
	}
	A[i] = '\0';
	for (i = 0; i < b; i++)
	{
		B[i] = b + '0';
	}
	B[i] = '\0';
	printf("%s", strcmp(A, B) < 0 ? A : B);
}
