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: Accepted)

a, b = map(int,input().split())
a_l = list(str(a)*b)
b_l = list(str(b)*a)
c = 0
for i in range(0,min(len(a_l),len(b_l))):
    if c == len(a_l)-1:
        print(int(str(b)*a))
        break
    if a_l[i] == b_l[i]:
        c += 1
        continue
    if a_l[i] > b_l[i]:
        print(int(str(b)*a))
        break
    if a_l[i] < b_l[i]:
        print(int(str(a)*b))
        break
