Book of Elementary Algorithms and Data structures

# Elementary Algorithms

Edition: $\displaystyle e = \sum \limits _{n=0}^{\infty }{\frac {1}{n!}} = 1 + {\frac {1}{1}}+{\frac {1}{1\cdot 2}}+{\frac {1}{1\cdot 2\cdot 3}}+\cdots = 2.718283$

This book introduces about elementary algorithms and data structure. It includes side-by-side comparison about purely functional realization and their imperative counterpart.

## Contents

I am adding exercises and answers to the second edition from 2023/03. I wrote the first edition from 2009 to 2017, then rewrote the second edition from 2020 to 2023. The PDF can be downloaded for preview (EN, 中文). The 1st edition in Chinese (中文) was published in 2017. I recently switched my focus to the Mathematics of programming, the new book is also available in (github)

## Install

To build the book in PDF format from the sources, you need the following software pre-installed.

• TeXLive, The book is built with XeLaTeX, a Unicode friendly version of TeX;

### Install TeXLive

In Debian/Ubuntu like Linux environment, do NOT install the TeXLive through apt-get. Go to TeXLive official site to download the setup script.

$wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl.zip$ unzip install-tl.zip
$cd install-tl$ sudo ./install-tl -gui text -repository http://mirror.ctan.org/systems/texlive/tlnet


In Windows, TeXLive provide a gui based installer, in Mac OS X, there's a MacTeX.

### Install ImageMagick and Graphviz

$sudo apt-get install imagemagick$ sudo apt-get install graphviz


### Others

You need the GNU make tool, in Debian/Ubuntu like Linux, it can be installed through the apt-get command:

$sudo apt-get install build-essential  In Windows, you can install the MSYS for it. In Mac OS X, please install the developer tool from this command line: $ xcode-select --install


### Build the book PDF

enter the folder contains the book TeX manuscript, run

\$ make


This will generate algoxy-en.pdf and algoxy-zh-cn.pdf. If you only need the Chinese version for example, you can run make cn instead. Run make force-cn or make force-en to force build the book.
