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)

'use strict'

const main = (INPUT) => {
  const [a, b] = INPUT.split('\n')[0].split(' ')
  console.log([a.repeat(b), b.repeat(a)].sort()[0])
}

main(require('fs').readFileSync('/dev/stdin', 'utf8'))
