Plagiarism Detector in C (Using Custom Hashing) *Overview This is a lightweight Plagiarism Detection Tool implemented in C, designed to compare multiple text files and identify similarities by leveraging a custom hashing technique. Instead of using standard hashing algorithms, it employs a simple and efficient bit-shift based hash function (e.g., using << 5) to generate hash values for words or n-grams. This method helps detect overlapping content quickly and with low computational overhead.

*How It Works Reads each input file and tokenizes the text into words or adjustable-sized n-grams. Applies a custom hash function that uses bitwise operations (such as shifting bits left by 5) to convert tokens into hash values. Stores these hashes in a hash table to track occurrences across documents. Compares documents by counting the number of shared hashes, calculating a similarity score based on overlapping content. Outputs similarity scores that help identify potential plagiarism or content reuse.

*Features Fast and lightweight file comparison using a custom bit-shift based hashing method. Adjustable n-gram size for fine-tuning similarity detection. Simple command-line interface. Outputs clear similarity scores between pairs of files. Scales to multiple files efficiently.
