The problem statement is missing, so I don’t have enough information to write a correct editorial.
“Codeforces 103388E - Escalator” could correspond to several different tasks (there are multiple “escalator” style problems involving queues, probabilities, DP, or simulation), and the solution approach depends entirely on the exact rules.
Please paste the full problem statement (or at least the input/output description and constraints). Once you provide it, I’ll write the complete editorial in the format you specified, including the derivation, algorithm walkthrough, and full Python solution.
