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 12.16.1) (judge verdict: Accepted)

function *main() {
  
  const [a, b] = (yield).split` `;
  const s = a.repeat(+b);
  const t = b.repeat(+a);
  console.log((s < t) ? s : t);
  
}
const iter = main();
iter.next();
require("readline").createInterface({input: process.stdin, output: process.stdout}).on("line", line => iter.next(line));
