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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<iostream>
using namespace std;

int main()
{
  int a, b;
  string a2, b2;
  cin>>a>>b;
  
  for (int i = 0; i<b; i++){
    a2 = a2 + to_string(a);
  }
  
  for (int i = 0; i<a; i++){
    b2 = b2 + to_string(b);
  }
  
  if (a2 > b2){
  	cout<< b2 << endl;
  }
  else{
    cout<< a2 << endl;
  }
  
  return 0;
}
