Mr Wong called me last night and asked me to help him with a P2 challenging question.

He told me it was F**king difficult because he can't get the solution according to the answer sheet at the back of the book.

I took around 5 mins to solve it and i think i took too long!

What about you?

Try it and tell him how easy it was.

Rmb, its just a P2 question, don't think too deep into it!
