Chapter 5

Chapter 5, A Dance with Trees, establishes an understanding of the tree data structure through examples including tree traversals, balancing trees, and Huffman coding.

This is the accompanying source code for Haskell Data Analysis Cookbook. Refer to the book for step-by-step explanations.

Recipes:

• Code02: Defining a rose tree (multiway tree) data type
• Code03: Traversing a tree depth-first
• Code04: Traversing a tree breadth-first
• Code05: Implementing a Foldable instance for a tree
• Code06: Calculating the height of a tree
• Code07: Implementing a binary search tree data structure
• Code08: Verifying the order property of a binary search tree
• Code09: Using a self-balancing tree
• Code10: Implementing a min-heap data structure
• Code11: Encoding a string using a Huffman tree
• Code12: Decoding a Huffman code

How to use

Setting up the environment

Install the Haskell Platform.

$ sudo apt-get install haskell-platform

Alternatively, install GHC 7.6 (or above) and Cabal.

$ sudo apt-get install ghc cabal-install

Running the code

A Makefile is provided in each recipe. Compile the corresponding executable by running make.

$ make

Run the resulting code. For example,

$ ./Code01

To clean up the directory:

$ make clean
