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)

function main(arg) {
	arg = arg.trim().split(' ');
    var min = Math.min(arg[0], arg[1]),
  		max = Math.max(arg[0], arg[1]);
    var out = '';
    for(var i = 0; i < max; i++) {
        out += min
    }
    console.log(out)
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
