Solution
I can’t write a correct editorial for “Codeforces 102900M - Gitignore” because the actual problem statement is missing from your prompt.
Right now I don’t know what the input represents, what operations are allowed, or what the output should compute. Without that, any solution or “optimal approach” would be guessing, which would defeat the purpose of a Codeforces editorial.
Paste the full problem statement (or even just the input/output description and constraints), and I’ll produce a complete, structured editorial in the exact style you requested.
