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 JavaScript (node.js v5.12) (judge verdict: Accepted)

"use strict";
main(require("fs").readFileSync("/dev/stdin", "UTF-8"));

function main(input) {
  input = input.split("\n")[0].split(" ");
  let small = "";
  let big = "";
  if (input[0] > input[1]) {
    big = input[0];
    small = input[1];
  } else {
    big = input[1];
    small = input[0];
  }
  console.log(small.repeat(parseInt(big)));
}
