Create Function With Canvas Undo Redo | Dataford Interview Questions

Create a function that returns a canvas with paint, undo, and redo methods.

Implement create_canvas(width, height, operations), where the canvas starts filled with None. Each operation is ['paint', row, column, color], ['undo'], or ['redo']. Apply the operations in order and return the final two-dimensional grid. A new paint after an undo must discard the abandoned redo history. Undo and redo are no-ops when unavailable.

Constraints

1 <= width, height <= 100
0 <= len(operations) <= 1000
Every paint operation has a valid row and column
Colors are strings or null
Operations are valid paint, undo, or redo commands

Function Signature
