Homework 1 posted 1/18, due 1/25 at the beginning of the class.
Homeworks must be turned in hard copies in class
All written homeworks should be completed by students independently, not in groups. 

1 (40 pts). Draw three separate deterministic finite automata for Identifiers 
(10 pts), Integer Literals (10 pts) and Comments (20 pts) defined in Appendix 
A.1, with the exception of the definition of Comments (see below).
(An important note: we do not allow the comments of the kind of /* */ to be 
nested, unlike what is said in the Appendix. Thus in the string /* /* abc */
*/,
we find a comment /* /* abc */, but the second appearance of */ is not part of 
the comment )

2. Textbook exercises: 2.1 e (15 pts) , f (15 pts); 2.5 a (15 pts);

3 (15 pts) . Textbook exercise 2.8 a. Also, describe in English what kind of 
strings are accepted in each final state.
