The book is not available anymore. I came to know that the book was very good.

Is there anyone who is willing to sell the book? If yes then please give me a personal message. Or if you have a pdf of the book then please share the link.

In this problem many did binary search and calculated the value of the function and stored the values in doubles and compared the results.

Shouldn't there be precision errors? As you are multiplying something with like (1.99999)^100?

I'm stuck with this problem

I've not found any blog or editorial on it and I couldn't understand the solution by reading a code. Can anyone please explain how to solve this problem in a few words?
