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>
#include<stdlib.h>
#include<ctype.h>
int main()
{
int a,b,num;
scanf("%d %d",&a,&b);
if(b>a)
{
num=a;
while(b>1)
{
num=num*10;
num+=a;
b--;
}
}
else
{
num=b;
while(a>1)
{
num=num*10;
num+=b;
a--;
}
}
printf("%d\n",num);
}
