Determine if two binary trees are the same or not (optimized for space)
AI-Expanded — inferred from the question title, not from the original candidate report
Given the roots of two binary trees, determine if they are identical in structure and node values. Implement your solution using an iterative approach with a stack or queue to ensure the space complexity is optimized to the height of the trees rather than the total number of nodes.
