Elementary Algorithms Edition: 0.6180339887498949 2017, Oct, 08 AlgoXY is an open book about elementary algorithms and data structures. This book doesn't only focus on an imperative (or procedural) approach, but also includes purely functional algorithms and data structures. The PDF version in English can be downloaded from github: https://github.com/liuxinyu95/AlgoXY/releases/download/v0.6180332/elementary-algorithms.pdf The book in Chinese was published. http://www.ituring.com.cn/book/1907 Errata and Exercise: https://github.com/liuxinyu95/AlgoXY/wiki/Preface Compared to the pdf, the published version contains many important corrections to the contents, equations, and figures. The original version provides examples in Haskell, C/C++, Python, and Scheme. I started A new branch jvm to provide examples in Java and Scala. -- Larry LIU Xinyu liuxinyu95@gmail.com
