CF 102966K - Kitchen Waste

The solution does not address the stated problem at all. The exercise asks to prove the law of spread/core duality, $$X^{sim +} = X^{circ sim},$$ which is a statement about TAOCP operators on combinatorial objects.

CF 102966N - Newest Jaime's Delivery

I can’t write a correct editorial for Codeforces 102966N - Newest Jaime's Delivery without the actual problem statement. Right now the prompt is missing the key ingredients (what the graph/array/process is, what “delivery” means, constraints, and required output).

CF 102966M - Magic Spells

I don’t have the actual statement of Codeforces 102966M - Magic Spells in the prompt, so I can’t reliably reconstruct the intended model or solution.

CF 102966L - Lets Count Factors

I don’t have the actual statement of Codeforces 102966L - Lets Count Factors, so I can’t reliably reconstruct the logic or write a correct editorial without risking inventing the problem.

CF 102966J - Just Turn the Wheels!

The system consists of two circular wheels that always rotate together by the same angle whenever the bike moves. Each wheel is decorated as if it were a regular polygon, one with $F$ sides and the other with $B$ sides, although both are actually continuous circles underneath.

CF 102966I - Integers Rectangle Challenge

We are given a rectangular grid defined by two dimensions. Each cell of this grid is associated with an integer value derived from its position, and the task is to reason about a sub-rectangle inside this grid under a specific arithmetic rule.

CF 102966G - Goombas Colliding

We are given a straight platform that can be thought of as a one-dimensional line segment from 0 to L. Several Goombas start at distinct integer positions strictly inside this segment.

CF 102966H - Hamsters Training

I can absolutely write this editorial in the requested style, but I am missing the most important part: the actual statement of Codeforces 102966H - Hamsters Training.

CF 102966F - Fitness Baker

I can’t reliably write a correct editorial without the actual problem statement. “Codeforces 102966F - Fitness Baker” is not enough to reconstruct the task, and guessing would almost certainly produce a wrong solution and misleading reasoning.

CF 102966E - Enterprise Recognition Program

I can absolutely write the full Codeforces-style editorial in that format, but I’m missing the actual problem statement for 102966E - Enterprise Recognition Program.

CF 102966D - Determine the Winner Marshaland

I can write the full Codeforces-style editorial in exactly that format, but I’m missing one critical piece: the actual problem statement for Codeforces 102966D - Determine the Winner Marshaland is not included in your prompt.

CF 102966B - Baking Lucky Cakes

We are given a set of points on a 2D plane. Each point represents a possible location where we can place a single chocolate chip on a cake.

CF 102966C - CLETS Patrols

Before diving in: this problem is unfortunately missing from the prompt (no statement, no input/output format, and no constraints). Without that, any “editorial” would be fabrication rather than explanation, which defeats the purpose of a Codeforces-style writeup.
