Really nice book. Easy book language. Easy to understand.
I bought this book last year though I already knew the language but this book forced me to read it again. If you really want to be coder then you should go in depth for which you can rely on this book. Only informative content and no irrelevant content.
The back exercises help you test you knowledge and the questions are also good. If you are not able to do even a single question then go through that topic again. Overall it is one of the best creation by an Indian author.
