Need A3P2 Clarifications

[Hien Goi]

Just wanted to clarify if we need to tokenize any of the following for a3p2:

1. while#
2. while<
3. <<
4. a<b
5. while[illegal character] <- (tokenize while and give error message or
simply give error message?)
and other similar cases to 5 eg. ***@.

I think implementing these cases will require many more states.

Thanks,

Hien.

<WHILE>

That depends on what your DFA looks like right now. If you need more
states then add them.

You should return an Error...there's not much point in returning the token
(it's fine if you happen to return one though).
