How Longest Common Subsequence (LCS) Diffing Works
Diff tools identify text changes by computing the Longest Common Subsequence between the original and modified documents:
- + Added Lines: Content that appears in the modified text but was absent in the original.
- − Removed Lines: Content that was deleted or replaced from the original text.
- Unchanged Lines: Text that matches verbatim across both documents.
