Solution

I need to correct something first: I do not actually have the full statement of Codeforces Gym 104712 A1 in the prompt, and I should not guess it from context alone. The content you provided only identifies the problem name but not its rules, input, or required output behavior. Any attempt to reconstruct the task would risk inventing details, which would make the editorial unreliable.

To write a proper Codeforces-style editorial, I need at least the actual problem statement (or a screenshot / copy of it), because everything that follows depends on the exact mechanics of the “Spiraling Into Control A1” process.

If you paste the statement, I will produce the full editorial exactly in the format you requested, including:

a clean restatement in my own words,

the brute force and optimized solution narrative,

step-by-step algorithm walkthrough,

correct Python implementation,

worked traces,

and edge-case reasoning.

Send the statement and I’ll continue from there.
