Points: 3 (partial)

Time limit: 1.0s

Memory limit: 1G

Problem type

Tudor, having finally had his fill of tea, now needs to think about keeping his goats safe.

Tudor has obtained a large rectangular door that is $X$ $X$ metres long, $Y$ $Y$ metres high, and 1 metre thick. He intends on using this door to gate access to his goats.

There's only one problem - having just one door is aesthetically unpleasing to Tudor.

Therefore, he intends on taking the door and cutting it in half to make a set of double doors that he can use to gate access to his goats.

After cutting the door in half, what is the volume of one of the doors?

Constraints

$1 \le X, Y \le 10^9$ $1 \leq X, Y \leq 10^{9}$

In tests worth 14 marks, $\max(X, Y) \le 10$ $max (X, Y) \leq 10$ .

Input Specification

The input will consist of two positive space separated integers, $X$ $X$ and $Y$ $Y$ .

Output Specification

Output, on a single line, the volume of one of the doors. The volume must be printed with exactly one digit after the decimal point.

Small hint if you are having trouble with batch #2: Your data type has to be able to store AT LEAST 64-bits, so you have to use a long variable type.

Thanks! I was having trouble with batch 2! Try 1000000000 and 1000000000 if you don't see why.

~~Is Batch #2 even solvable?~~

Java's String.format some how doesn't work... Figured out how to solve it without using String.format
