dont read space in the input.

What do you mean? Firstly I read two lines of text, then I parse it using '+' and '-' as parsing symbols, and, after that I delete spaces from every substring I got. And I have WA#12.
Do you want to say it is wrong algo? If so, could you give a test to clarify what you mean, please?
