Bests & Worsts Reviews from Amazon

The Good stuff: 1. Book has a very good set of problems. 2. Covers a lot of ground. 3. Problems in here are hard and one wouldn't find them elsewhere. The bad stuff: 1. Really poor explanations. The authors assume that you know the algorithms and for a lot of complex problems there is a one-two line explanation. If someone knew these he or she won't be looking for a book. 2. While reading through I found myself increasingly looking on the web for solutions/explanations for the questions. Making the point moot for buying this book in the first place. Very frustrating! I get it that the authors are accomplished and brilliant. But, explaining is something that they haven't been able to provide in the book. Having said that it has some very good questions sprinkled. My advice stick to Leetcode or Hackerrank.
