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, b, i;
    scanf("%d%d", &a, &b);

    if ( a <= b ) {
        for ( i = 0; i < b; i++ ) {
            printf("%d", a);
        }
        printf("\n");
    }
    else {
        for ( i = 0; i < a; i++ ) {
            printf("%d", b);
        }
        printf("\n");
    }

    return 0;
}
