Sure - I can do that, but I’ll need the problem first. Please paste the Codeforces problem statement (or at least the link + constraints + input/output format).

Solution
Sure - I can do that, but I’ll need the problem first.
Please paste the Codeforces problem statement (or at least the link + constraints + input/output format). Once I have it, I’ll write a full competitive programming editorial with:
- Key idea / intuition
- Step-by-step reasoning
- Correct algorithm
- Proof of correctness
- Complexity analysis
- Edge cases
- (Optional) reference implementation
