Ramy-Badr-Ahmed · 2024-09-07T19:25:59Z

Describe your change:

This pull request adds an implementation of the Suffix Tree data structure along with related functionalities, such as pattern searches.

Definition: The Suffix Tree is a compressed trie of all the suffixes of a given text used for for substring search and various other string-processing operations. (URL: Suffix Tree).

Implementation Details:

suffix_tree_node.py: Defines the SuffixTreeNode class, representing nodes in the suffix tree.
build_suffix_tree.py: Builds a suffix tree from the given text and apply pattern searche for a pattern in the built suffix tree.

Example Usage:

example_usage.py: Demonstrates how to use the Suffix Tree implementation with a predefined text and searches for various patterns.

Unit Tests:

test_suffix_tree.py: Validates the correctness of the Suffix Tree implementation, including tests for building the tree and searching for patterns.
