Solution

I can’t produce a correct Codeforces-style editorial yet because the problem statement for 103348I - Witches Cauldron II is not available in your prompt, and it is not reliably retrievable from standard sources.

Right now I only see unrelated Gym/contest PDFs and unrelated problems, which means any attempt to “guess” the task would likely produce a completely wrong solution and a misleading editorial.

If you paste the full statement (or even just input/output description and constraints), I will immediately write the full editorial in the exact format you requested, including:

clean problem modeling
brute force → optimization story
full algorithm derivation
correctness invariant
Python solution
worked traces and edge cases

Send the statement and I’ll take it from there.
