Solution

The problem statement isn’t included in your message, so I don’t actually have the rules of “Fill the World with Argon” to base an editorial on.

Right now I only know the title, which isn’t enough to reconstruct the task reliably (Codeforces problem titles are often abstract and not uniquely determining).

If you paste the full statement (or even just input/output description + constraints), I’ll write the complete editorial in the exact format you requested, including:

clean rephrased problem understanding
brute force → optimal transition
full algorithm walkthrough with invariants
Python solution
worked traces
complexity + edge cases

Send the statement and I’ll proceed.
