Solution

The problem statement for Codeforces 103401G - Environmental friendly is missing from your prompt, so I can’t reconstruct a correct editorial without risking inventing details.

If you paste the full statement (or even just the core description + constraints + samples), I’ll write the complete editorial in exactly the format you specified.

Once you send it, I’ll:

restate the problem in clean terms,
derive the naive solution and why it fails,
build up the optimal approach step by step,
include full walkthroughs, proofs, and tested Python code.

Just drop the statement and I’ll continue.
