What? that is C code?? I have learned a bit of C++. But i never seen that kind of word... Maybe it's the advanced level of C... huehehhee... i think i only learned the beginner level of C... hahahaha... huhuhuhu... T_T

Well, to be fair, it is also C++. (C is practically a subset of C++) Its not really that advanced, either.

Try to test the function by sending random values and take a look to the output,
after passing a bunch of values you will see a pattern.
then it will be easy to find the answer.

Hello hackers.
This is my first post.
My English isn't so good.
You see, I'm from Greece and I don't know how to translate some things in English.
I am also new in Linux, thanks to this forum, and I don't know how to run a c++ project.
Neither how to find and install translators, programs, etc.
I managed to solve some of the tests in windows, which I am using for years, but Linux is hard for me.
About the test, I can only say that
it has an integer input
it tests if both values (&) have the price of zero
But how can x and x-1 have the same price?
I think it always return false (-1)
Could you please help me?

In most languages, C and C++ included, true is any non-zero number.
This makes -1 true.
0 is the only false value.
Otherwise I don't know much more about this puzzle.
Oh, to compile a C or C++ program on GNU/Linux, you would do:
, if it's a c program
OR
, if it's a c++ program.
Obviously change file.cpp or file.c to the filename of the source code. If they compile without problem, you can go ahead and do:
Which will run the code.

It's like "something of something", or /.* of .*/ in regex.

I know the answer...I think. I mean I know what the function does, but I can't seem to word it correctly, and I speak english as a native language...
Nevermind, I just realized there are three ways to say it in a blank of blank format. I was only trying two of them.

Hey, do not write the answer here!
It spoils the challenge. Everyone can see it.
You should delete it as soon as possible.
Edit: Thanks.
