Welcome to the ClassTrie wiki!

This creation Is the data trie.... A TREE....

In this issue the alphabet trie is created ; The strings are added by character with a STOP character at the end of the insert;

A Search function will be created ; to search the trie for words or search a string for words contained in the trie; ADDED

This method will be further extended to handle numerical inserts as well as DATA inserts for usage as a Conversation Trie;

I was searching for a method to combine various conversation trees; into a single tree;

This will be it!

The Trie "TRY"Tree

The word trie is an inflix of the word “retrieval”, because the trie can find a single word in a dictionary with only a prefix of the word.

The Trie Tree is a very straight forward data structure. It is a simple tree where the nodes have an alphabet associated with them. It is sometimes called a "Prefix tree" / "Suffix tree" ....

By structuring the nodes in a particular way, words or strings can be retrieved from the structure by traversing down a branch path of the tree.

_ Currently Tries are used for Storing "Characters" within a String... Although these does not need to be the case; Sentences can also be stored (Each Word in a Node) ; Paragraphs can be Stored (Sentences in every node) ; Even Structured Data can be stored in a Trie tree. (using the NODES as Addresses, Data stored in the Final node); _

Trie Tree Example

This offering Attempts to cater for all paradigms ; Noticeably the differences are only measured by the Insertion / Search / Deletion Process.

### For advanced Search capabilities data can be added iteratively. ### For a single word of Three letters (3 insertions) Cat > at > T

This allows for all suffix and Prefixes to be stored in the Tree. A Marker is used to Mark the end of a String Entry...

CAT(StopChar) AT(StopChar) T(StopChar)

Where as if a single Insertion is used

CAT(StopChar) Cat / Ca / C <<<< Maybe found > But! At / T <<<< Cannot

Carpet Car < But cannot Find Suffix > Pet <

Common functions are ;

**Find Prefix **

**Find Suffix *

**Count Nodes **

**Deepest Node **

Add(by character) > As Single / Iteratively

Add(by Word) > As Single / Iteratively

Add(by Sentence) > As Single / Iteratively

***UPDATES ***

WORKING!!

Insert function;

FindPrefix function;

**FindWord Function; **

**CreateTrie Function; **

ToString Function (displays contents of tree in report form);

ToView Function (displays Contents of Tree in TreeviewControl);

Saved as STRUCTURE;

Note To extend This structure (just update the CharID to accomodate NewStringID, as well as Update ADD Function)

Probably the NodeID Pointer can be removed (Not Req)

Project build 1 was as class library (for Sharing) _Project build 2 was as EXE (for testing) _ Built With .net 4.52

02/06/2018 Updated Trie to Tree (Universal Tree) Function ADD / Find Prefix / Find Word / CountWords / Count Node - StopChar nodes / Find Lowest Node - StopChar

NEEDS - DELETE WORD CMD -

Universal Tree - can also Hold Data at nodes using an Alphabetical Tree..... To be Added. (Input Data @ StopChar)(GetData From StopChar) Then Given a CharacterString Address (Data can be Added or Removed or located) Searching Should be done Via CharacterString (Not Data) or GetNode @ CharString Address (Edit/Remove)

ADDED BINARY TREE POSTORDER / PREORDER TRAVERSAL / INSERT / CONTAINS ADDED EXTENSIONS FOR TREENODE OPERATONS)

**UPDATES COMMITED **; ** ADDWORD ... Adds word iteratively ie: carpet/arpet/rpet/pet/et/t WORKING **; <<<<< Contains all possible prefixes in tree from word ** WORKING **; Various methods counting Nodes / find deepest nodes / Count Prefixs in tree / CountWords in Tree / ** WORKING **;

ADDED ::: Add Sentence To TRIE: Breaks sentence into words adding each word to the trie ; Sentences can be added as a single branch or as iterative branch "The cat sat on the mat", "cat sat on the mat", "sat on the mat", "on the mat", "the mat", "Mat".
