Your solutions for flood fill are correct and efficient. Both BFS and DFS approaches are well-implemented.

Strengths:

• You correctly handle the base case where the new color is the same as the original color.
• You use appropriate data structures (deque for BFS) and recursion for DFS.
• The code is clean and easy to understand.

Areas for improvement:

• In the BFS solution, you can change while len(q): to while q: for better readability.
• Consider moving the import statement for deque to the top of the file to avoid importing inside the function (though it's not a big issue).
• For the DFS solution, note that recursion might lead to stack overflow for very large images (but the problem constraints are small, so it's acceptable).

Overall, both solutions are excellent.
