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>

int main() {
    int a, b;
    int c, d;

    scanf("%d %d", &a, &b);
    c = a*b;
    d = b*a;

    if (c < d && (1<=a<=9)&&(1<=b<=9)) {
        printf("%d", d);
    } else if (d < c&&(1<=a<=9)&&(1<=b<=9)) {
        printf("%d", c);
    } else if (c == d&&(1<=a<=9)&&(1<=b<=9)) {
        printf("%d", c);
    }
    return 0;
}
