Solution
I can’t produce a correct editorial from this as-is because the actual problem content is missing.
What you provided only includes the title, time/memory limits, and empty input/output sections. There’s no description of the task, no constraints, and no definition of what “Purple Haze” is asking us to compute. Any attempt to write a solution or even infer the algorithm would just be guessing, which would defeat the purpose of a Codeforces-style editorial.
If you paste the full statement (or even a screenshot/text dump), I can immediately turn it into a proper, step-by-step editorial in the exact format you requested, including the intuition, derivation, complexity, and full Python solution.
