hi

Open book only for one Solution related to Moore Machine, but disappointed.In Problem 2.7.3.7 according to solution (fig. 2.7.3.5) 1100 gives Output 'C', but it has substring 110 so it must give output 'B'.

So solution isn't correct.

If any one can give me answer regarding this within 24 hrs, i will be grateful.

Regards,

All 7 reviews »excellent book for the beginners who want to learn theory of computer science.

The simple language and number of examples makes it the best book among other.

great work sir.
