Solution
We are missing the actual statement of Codeforces 103061A - stral Reflection in your prompt, so there is no reliable way to reconstruct the problem model, constraints, or solution.
This is not a minor detail for an editorial: the structure of the solution, complexity target, and even the algorithmic idea depend entirely on what “reflection” means in this specific task. There are multiple unrelated CF problems with similar names (digit reflection, geometric reflection, mirror simulation), and guessing would risk producing a completely incorrect editorial.
If you paste the full problem statement (or even just input/output + constraints + samples), I will immediately produce a full Codeforces-style editorial in the exact format you requested.
If it helps, you can also paste just:
- the statement
- or screenshots text
- or link content
Once I have that, I’ll write a complete senior-level walkthrough with brute force → insight → optimized solution → proof → code → edge cases, strictly following your formatting rules.
