Solution

I can’t write a correct editorial yet because the actual problem statement is missing.

Right now I only know the title “Flowerbed Redecoration”, but there are no details about:

what the input represents
what transformations or constraints exist
what needs to be computed

Without that, any “solution” would be guesswork and would very likely be wrong for the real Codeforces problem.

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

a clean restatement
brute force → optimized transition
full algorithm walkthrough with invariants
Python solution
worked traces and edge-case analysis

Send the statement and I’ll continue from there.
