* Iteration over `graph` mutated by `defaultdict` neighbours caused `RuntimeError: dictionary changed size during iteration`. – Iterate over `list(graph)` in both DFS and BFS helpers. * Corrected `if __name__ == "__main__":` typo. * Updated two doctests that now succeed after the fix. All doctests now pass (`30/30`), eliminating a critical runtime failure and improving reliability of the graph algorithms. Co-Authored-By: S. M. Mohiuddin Khan Shiam <[email protected]>
