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 Go (1.14.1) (judge verdict: Accepted)

package main

import (
	"fmt"
)

func main() {
	var a, b int
	fmt.Scan(&a, &b)
	if a == b{
		for i:=0; i<a; i++{
			fmt.Print(a)
		}
	}else if a > b{
		for i:=0; i<a; i++{
			fmt.Print(b)
		}
	}else{
		for i:=0; i<b; i++{
			fmt.Print(a)
		}
	}
	fmt.Println()
}
