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 (3.4.3) (judge verdict: Wrong Answer)

a,b=map(int,input().split())
A=str(a)*b
B=str(b)*a
if len(A)>len(B):
  print(B)
elif len(B)>len(A):
  print(A)
else:
  for i in range(len(A)):
    if int(A[i])>int(B[i]):
      print(A)
    elif int(A[i])<int(B[i]):
      print(B)
  print(A)
