1 \leq B \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the value A \times B as an integer.

Sample Input 1

2 5

10000

Solution in Python (3.8.2) (judge verdict: Runtime Error)

n = int(input())
a = [int(i) for i in input().split()]
number =1

for i in a:
    if i==0:
        print(0)
        exit()
    number *= i
    if number > 10**18:
            print(-1)
            exit()

print(number)
