First round of this book has just been finished. It is a wonderful book.
It focuses on teaching readers how to analyze & solve problems, including typical CS algorithm problems and also some interesting Maths problems. But actually I am not interested in the Maths part, though it is still helpful and challenging.
The “upper bound” of this book, referring to the CS field, is Dynamic Programming. Yes, DP should be the toughest topic during interviews of most IT companies – maybe not limited for Google.
The most moving point of this book, is that it demonstrates the thought flows of problem solving – unlike CLRS. Also it offers some quite powerful programming skills.
Yes, a 2nd round is necessary.
