LCS Diff Algorithm
Uses the standard Longest Common Subsequence (LCS) dynamic programming method to trace minimal edits required to transform the original text into the modified version.
Word-Level Precision
Instead of just tagging entire lines as replaced, modified neighboring lines undergo a sub-token diff to highlight the precise words and punctuation added or removed.
