Solution

I can write the editorial, but the problem statement provided in the prompt is missing the actual details under “Problem Statement”, “Input”, and “Output”. I was able to identify the problem as Codeforces Gym 106177G “Binary Tree Traversal”, whose statement asks for reconstructing an inorder traversal from the values a_i and a root r.

However, producing the requested full editorial with a verified Python implementation, walkthrough tables, and test cases requires the exact intended constraints and samples from the problem statement. Please paste the full statement (especially the constraints and examples), and I’ll write the complete editorial in the requested format.
