The Coding Monkey Collections

This library contains collections and algorithms that are not part of the standard .NET Generic Collections. This library is compatible with the full .NET library, as well as .NET Core.

Binary Search Tree Implementations

There are three Generic Binary Search Tree implementations in the library. All three require that the Key implement IComparable, and that the keys are unique.

Basic Unbalanced Binary Search Tree

The BinarySearchTree class is the base class for the other more specialized versions. The basic tree will degrade in performce over time, as items are added depending on the order in which they are added. Adding the same keys to the tree in different orders can affect performance because the tree does not self balance. Average times for all operations are therefore O(log n) with a worst case of O(n).

Red Black Tree

A Red Black Tree is a type of self balancing binary search tree. Each node tracks a color enumeration, and therefore stores slightly more information about the node than a standard binary search tree. Because it is self balancing, all operations are O(log n).

AVL Tree

The AVL Tree is an implementation of a balanced binary search tree named after Adelson-Velsky and Landis. An AVL Tree will be slightly faster than a Red Black Tree because the balancing is more strict. All operations are O(log n).

Iterators

Binary Search Trees support iteration in differnet ways. All of the Binary Search Tree implementations support the following iterators:

Skip List

Skip lists are a data structure that defines a linked hierary of sublists, with each sublist having fewer items than the one before. In many ways its a combination of an array with a linked list. Search and insert are both O(log n).

This implementation implements IDictionary<TKey, TValue> and can be used as a drop in replacement for the Dictionary class, assuming that TKey implements ICompareable<T>.

Linked List

This linked list implementation was origionally written prior to .NET 2.0, which is when Microsoft added its own LinkedList implementation to the System.Collections.Generic namespace. It supports many of the same operations, though with slightly different method names.

Command Line Argument Collection

The command line argument collection takes the argument string from a main function, and parses command line switches, adding them to an internal dictionary.

Valid parameters forms are: {-,/,--}param{ ,=,:}((",')value(",'))

Examples: -param1 value1 --param2 /param3:"Test-:-work" /param4=happy -param5 '--=nice=--'

Sorting Algorithms

Implemented several popular sorting algorithms that all operate generically on any collection wich implements IList<T> where T implements IComparable. A summary of the different performance characteristics of these algorithms is also available.

In Place Sorting Algorithms

These algorithms modify the list which is passed into the sorting function. They all derive from IInPlaceSort<T>

Out of Place Sorting Algorithms

These algorithms create a new list sorted list from the unsorted list passed into the sorting function. They all derive from IOutOfPlaceSort<T>
