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(){
    int a,b;
    char buf[10] = "";
    scanf("%d%d",&a,&b);
    if(a < b){
        a^=b;
        b^=a;
        a^=b;
    }
    int i;
    for(i = 0; i < a; i++){
        buf[i] = '0' + b;
    }
    buf[i] = 0;
    puts(buf);

    return 0;
}
