Introduction to Discrete Structures for Computer Science and Engineering

This is really a classic. Although published in 1973, this book was by far the best I read about Discrete Math. The authors used a very didatic sequence explaining first the main ideas on Set, Group, Function, Binary Relations, etc.. to go on further in more abstract stuff. As I read this marvelous book It seemed to me that the authors had worried about explaining things very clearly. I was lucky in finding a (used) copy. I'm so sorry this book is out-of-print and the new generations won't be easily exposed to such a excelent and enjoyful book. I was very happy I could find it. It was really a good buy.
