A. Laaksonen, Guide to Competitive Programming. Overall a good book, enormous amount of graph to explain algorithms compared to those lazy math books. C++ code are shown but have some serious bugs there. Also actually not that much snippets are shown, author can simply write Python that everyone can read and work interactively. Some mysterious decisions in algorithms are not being evaporated why or how that work. I might extend this book if it is licensed in CC4.0 or something.
