Edit Graph Lab
Diff as a shortest-path search, with Myers' algorithm animated.
What it does
Shows students how a diff tool decides what changed between two files. You type two texts and see the grid the classic Myers method searches, step by step, with each step explained in a sentence, ending in the familiar line-by-line diff. A compare view runs four diff methods on the same input and highlights where they disagree, and seven worked examples cover known puzzles. Instructors can generate practice questions and export them as Markdown or a quiz file that learning systems import.
Good to know
Its diffs can differ from git's, because it skips git's clean-up pass and may pick a different equally short answer.
