PEG Judge - Shortest Code

Shortest Code Contest

Write a piece of code to solve some mathematical expressions.
These mathematical expressions will be very simple - each expression will consist of two numbers and a single operation.
All numbers will be positive integers less than 100, and the only operations will be +,- and *.
There will be multiple test cases - the first line will indicate the number of tests.

Oh, I almost forgot to mention: you can't use semicolons!
Your score will be (86 / N)² x 10, where N is the number of non-whitespace characters in your code.

Why can't Python solutions be submitted? If the solution doesn't include a semicolon, I don't see why it shouldn't be accepted (even if it is a really simple solution).

In certain interpreted languages such as Python and Ruby, semicolons are optional and thus the problem is trivial.
The whole reason semicolons are disallowed is to make the problem somewhat challenging.

You can declare variables with int main():
e.g. int main(int a, int b) ...

What about it? You can't use it because that would require a semicolon!

[s]If you '#include <rope.h>', you won't need the using namespace std; (and it has cout/cin)
This won't work in Visual C++, though.[/s]
Edit: #include <list.h> is better

zerglingrush on Dec 21, 2008 - 2:32:56 am UTC Marking Scheme

(1/1)

I'm just wondering (although probably a lot more work for nothing), since C obviously has an advantage, can there be separate marking schemes for C and C++?

C doesn't have that big an advantage over C++, so no, only one marking scheme.

It's not like we even know C (or at least I don't), so you can just try figure it out.

The only difference between C and C++ that is significant for this problem is that you don't need any #include statements to input/output in C, but you are restricted to the following I/O routines (no cin/cout):

OK. Apparently 86 chars is possible, I'll leave it at that.

Without that rule, there's no challenge whatsoever and it would be a very very easy 10 points.
