Problem:
Score : 100 points

Problem Statement

Compute A \times B.

Constraints

1 \leq A \leq 100

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

Sample Output 1

10

We have 2 \times 5 = 10.

Sample Input 2

100 100

Sample Output 2

10000

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

a,b = input().split()

a = int(a)

b1,b2 = map(int, b.split('.'))
b = b1*100 + b2

ans = (a*b)//100

print(int(ans))
