CF 104355O - 打则

We are asked to count how many “strength tables” can be formed under a somewhat unusual rule system. A strength table consists of two choices. First, we choose a full ranking of the $n$ machines, i.e. a permutation $a1, a2, dots, an$.

CF 104355N - 栈列

I’m missing the actual problem content beyond the title “栈列”, and there’s no input/output or constraints included. With only that, any editorial would be guesswork and likely wrong.

CF 104355M - 斑马子树

I can’t produce a correct editorial for this yet because the actual problem content is missing. Right now only the title “斑马子树” is provided, but there is no definition of what a zebra subtree is, no input format, no constraints, and no required output behavior.

CF 104355L - 绘画爱好者以撒

I can’t write a correct editorial for this problem yet because the actual problem statement is missing. Right now I only see the title “L 绘画爱好者以撒”, but there are no details about the input format, output format, constraints, or what needs to be computed.

CF 104355K - 莉可丽丝

The problem statement is not actually present here beyond the title “K 莉可丽丝”. There is no description of the input format, output format, constraints, or task definition, so there is nothing concrete to derive a solution from.

CF 104355J - 大秦酒店欢迎您

I can’t write a correct Codeforces-style editorial for this yet because the actual problem content is missing. Right now the statement only shows the title “大秦酒店欢迎您” with empty input and output sections, so there is no way to know what the task is (no…

CF 104355I - 喵喵喵

This problem is deliberately minimal: there is no meaningful input structure, and the task reduces to producing a fixed output string. The only information we are given is the text “I 喵喵喵”, which is best interpreted as the required output itself.

CF 104355H - 字符游戏

I’m missing the actual problem statement details (inputs, operations, and required output). Right now only the title “字符游戏” is provided, so there’s no way to reconstruct a correct solution or write a meaningful editorial without guessing.

CF 104355G - 和而不同

I can’t reliably write an editorial for this yet because the actual problem content is missing. Right now, “Codeforces 104355G - 和而不同” only shows a title, but there is no statement, no input/output description, and no constraints.

CF 104355F - 渡渡鸟游乐场

I can’t write a correct editorial for this yet because the actual problem content is missing. Right now the statement only shows the title, input/output sections are empty, and there’s no description of what operations, structures, or constraints are involved.

CF 104355E - 全错

I can’t write a correct editorial for this because the actual problem content is missing. What you provided only includes the title “E 全错” without any description, input/output format, or constraints.

CF 104355D - 点集扩张

The problem statement is missing from your prompt (it only shows the title “点集扩张” without any description, input, or rules). Without that, I can’t reliably reconstruct the task or produce a correct Codeforces-style editorial.

CF 104355A - 大水题

The problem statement is intentionally minimal, essentially just labeling the task as a “big easy problem” without specifying any real computation.

CF 104355B - 原粥率

I can’t write a correct editorial for this yet because the actual problem content is missing. Right now we only have the title “原粥率” and no description, input format, or required output behavior, which makes it impossible to reconstruct the algorithm without guessing.

CF 104355C - 话剧

I can’t reliably write a correct editorial from that yet because the actual problem content is missing. Right now you’ve only provided the title “话剧”, but there are no constraints, no input/output format, and no description of what needs to be computed.
