I can’t reliably write a correct editorial for Codeforces 106272B - MAX? MEX? because the problem statement you provided is empty in the prompt.
Right now I only see the title, constraints placeholders, and no definition of the input/output or the task. Since this kind of problem typically hinges on very specific definitions of “MAX” vs “MEX” behavior, guessing would very likely produce a completely wrong solution and misleading editorial.
If you paste the full statement (or even a screenshot / partial text), I can immediately produce a complete Codeforces-style editorial in the exact format you requested, including the reasoning, optimal approach, code, and edge cases.
