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 Python (3.8.2) (judge verdict: Runtime Error)

input_line=input().rstrip().slpit()
num1 = int(input_line[0])
num2 = int(input_line[1])

if (num1 > num2):
  print(str(num2)*num1)
elif (num1 < num2):
  print(str(num1)*num2)
elif (num1 == num2):
  print(str(num1)*num2)
