Hello,
What exactly does the error message from Problem #150 Introducing RegExp mean? I get this:
Sorry, for test data<br/><br/>bch 0B21
Does it mean 0B21 is incorrectly substituted? Thank you in advance.
Never mind, I found the mistake. I used + instead of * for one digit hex ending in h. Still have no idea how the error message is related, but it's not too important now.
That's fine! Thanks for self-resolving this :) regretfully it is bit difficult to make checker always produce relevant error messages since it judgest mistakes by outcome and sometimes understands it differently...
