Deep Compare Binary Trees

MediumPython

Problem

Implement a function to perform a deep comparison between two binary trees and return whether they are structurally identical.

Represent each tree as a nested list [value, left, right], where an empty child is None. Return True only when both trees have the same structure and equal values at corresponding nodes. Return False otherwise.

Constraints

  • Each non-empty node is represented as [value, left, right].
  • A missing tree or child is represented by None.
  • 0 <= number of nodes in either tree <= 1000
  • Node values are integers.
  • Corresponding values must match in addition to structure.
