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,i,j,sum;
    scanf("%d %d",&a,&b);
    if(a<b){

        for(i=0,j=1,sum;i<b;i++,j=j*10){
            sum = sum + a*j;
        }
        printf("%d\n",sum);
    }
    else{
        for(i=0,j=1,sum;i<a;i++,j=j*10){
            sum = sum + b*j;
        }
        printf("%d\n",sum);
    }

    return 0;
}
