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 Kotlin (1.0.0) (judge verdict: Wrong Answer)


import java.lang.*

fun main(args: Array<String>) {
    val (N, A) = readLine()!!.split(" ")
    println(Math.min(ret(N),ret(A)))
}

fun ret(str : String) : Int{
    var ans = ""
    for(i in 0 until str.toInt()){
        ans += str
    }
    return ans.toInt()
}
