Solution

We are missing something important: the actual statement for Codeforces Gym 106014A, Mystic Quest. The Codeforces archive page does not expose the problem text directly in the results, and without the statement there is no reliable way to reconstruct the intended solution. Anything else would turn into guesswork, which is exactly what we want to avoid in an editorial.

If you paste the problem statement (even just the input/output description and constraints), I can write the full Codeforces-style editorial exactly in the format you requested.

To make this smooth, you can send:

the full statement, or

a screenshot / copy-paste of the problem, or

even just the sample input/output plus constraints if that’s all you have.

Once I have that, I’ll produce a complete editorial with:

a clean problem restatement,

derivation of the optimal idea from brute force,

full algorithm reasoning,

code,

and edge case analysis.
