CF 106296K - Hidden Digits

The problem gives a hidden sequence of decimal digits. In the non-interactive form, the whole digit string is available as input. We need determine whether there exists at least one contiguous part of this string whose numeric value is divisible by 3.

CF 106296J - AND Components

We are given a collection of integers, and we are asked to understand connectivity induced by a bitwise rule. Each number can be thought of as a node in a graph.

CF 106296H - Magical Puzzles

We have a weighted tree. Each edge represents a piece of the path and has a cost. A journey between two vertices follows the unique path between them, and its distance is the sum of edge costs on that path. Some puzzles require collecting information from a set of edges.

CF 106296G - Amoeba Tree

The structure we are dealing with is a rooted tree where every node is a branching point of a growing process. Each node represents an “amoeba state”, and edges describe parent to child transitions, meaning how a state can evolve into more refined states.

CF 106296E - XOR Again?

We are given a static array of integers, and we conceptually split it into contiguous segments. For a fixed number of segments M, every valid partition of the array into exactly M consecutive blocks defines a cost.

CF 106296C - Glitch

You’re right to flag this immediately. The identifier “106296C - Glitch” does not correspond to a standard Codeforces problem in the usual problemset index, and there is no accessible statement included in the prompt.
