Algorithms are step-by-step instructions for solving problems, most of which have already been solved, tested and proven to be effective. The second edition of "Grokai algorithms" simplifies the study, understanding and use of algorithms. In this book you will find simple and intelligible explanations, more than 400 funny illustrations and dozens of examples. Reading it is the best way to unleash the full power of algorithms and prepare for programming interviews. Deep knowledge of mathematics is not required! You will learn about the main algorithms that allow you to speed up programs, simplify code and solve common programming problems. Start by sorting and searching, then develop your skills to tackle complex tasks such as data compression and artificial intelligence. Learn to compare the performance of different algorithms. The second edition gives new, more detailed descriptions of trees, NP-complete tasks, and the example code has been updated to Python 3. It's time to rattle algorithms in a new way!
