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 L, S;
  if (a >= b) {
    L = a;
    S = b;
  }
  else {
    L = b;
    S = a;
  }
  int ans;
  ans = 0;
  for (int i = 0; i < L; i++) {
    ans += S * 10 ^ L;
  }
  cout << ans << endl;
}
