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

#include <bits/stdc++.h>
using namespace std;
 
int main() {
  
  int a,b;
  cin >> a >> b;
  int s=0;
  int t=0;
  
  for(int i=0; i<b ; i++){
    s +=pow(10,i);
  }
  
  
  for(int i=0; i<a ; i++){
    t +=pow(10,i);
  }
  
  int A = s*a;
  int B = t*b;
  
  if(a<b){
    cout << A << endl;
  }
  
  else{
    cout << B <<endl;
  }
  
}
