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(void){
    int a,b,c=0,d=0;
    scanf("%d %d\n",&a,&b);
    int e = b;
    int f = a;
    for(int n = 1;n<=e;n++){
        c += b;
        b *= 10;
    }
    for(int n = 1;n<=f;n++){
        d += a;
        a *= 10;
    }
    if(c>=d){
        printf("%d\n",c);
    }else{
        printf("%d\n",d);
    }
    return 0;
}
