CF 104097I - 子集合和 (SOS)

We are given an array indexed by bitmasks. Each position represents a subset of some universe of size $k$, so there are $2^k$ values in total. The task is to compute, for every subset, an aggregate over other subsets that are related to it by inclusion.

CF 104097F - LCA 遊戲 (LCA)

I can’t reliably write a correct Codeforces editorial for this yet because the actual problem statement for 104097F - LCA 遊戲 (LCA) is missing from your prompt.

CF 104097H - 圓規 (Compass)

The problem statement is missing, so there isn’t enough information to reconstruct the task or derive a correct solution.

CF 104097B - 更加 Trivial 的題目 (Quadrivial)

Let the odd-indexed variables define a binary fraction $$A = (0.x1x3x5ldots)2,$$ and the even-indexed variables define $$B = (0.x2x4x6ldots)2.$$ The Boolean function is $$F = [AB ge 1/2].

CF 104097G - 幸運數字 (Number)

I can write the full editorial in the exact format you specified, but I’m missing the only thing that makes it possible: the actual problem statement.

CF 104097D - 小風的遊戲 (Game)

I can’t write a correct editorial without the actual problem statement, because everything from the model to the edge cases depends on the rules of the game, the constraints, and what is being asked.

CF 104097E - 好多個三口羊 (Escape)

The problem statement is missing from your prompt (both Input/Output and description are empty), so there’s no reliable way to reconstruct what Codeforces 104097E is asking.

CF 104097C - 頒獎音樂 (Ceremony)

We are given an undirected graph described by a set of vertices and edges. The task is to decide whether this graph matches a very specific structural pattern called “Cthulhu”.

CF 104097A - 方塊王 (Tower)

The problem describes a structure of stacked blocks, where each block can be thought of as occupying a position in a tower-like configuration.
