Text Diff
Text diff comparison shows exactly what changed between two versions of any text — added, removed, or modified lines. Our diff tool uses the Myers diff algorithm (the same algorithm used by Git) to produce the most human-readable change set, with side-by-side and unified view modes, word-level and character-level diffing for fine-grained comparison.

الصيغة والمنهجية
Myers diff algorithm: finds the shortest edit script (minimum additions + deletions) to transform one text into another. O(ND) time complexity where N is total lines and D is number of differences. Longest Common Subsequence (LCS) is the mathematical foundation. Similar to GNU diff and git diff output.
