#### Common Techniques for Code Plagiarism Detection

* **String Matching:** Compares code line by line to find exact matches.
* **AST (Abstract Syntax Tree):** Analyzes the structure of code to detect logical similarities, regardless of formatting.
* **Tokenization:** Break down the code into smaller parts to identify recurring patterns.
* **Machine Learning:** Uses AI to identify subtle forms of plagiarism that traditional methods may miss.
* **Levenshtein Distance:** Measures the similarity between two code samples by counting the minimum changes required.
