changed 'an' to 'a', thanks ;-)

If you can provide a function to detect whether the multi line code is one-line, I'll very please to be able to let you write a number of lines of code solution. I don't have the ability to write the test code.

BTW: Why we should use a instead of an, it is in front of a vowel...

In fact, this solution very slow, I don't know how does it passed..

But it's hard to check whether the code is one line.
Thanks for your test, solve and feedback ;-)

Fixed, let me know what you think :D

now idea, must be a codewars issue.

Did you by chance try the bookmark as well? :)

is nothing happening at all when you press submit?
i've just tested it and it works appropriately

Point b fixed.

Thanks. Fixed point a, will look at point b tomorrow
