CF 104066F - Стрелочник
I don’t actually have the statement of Codeforces 104066F (“Стрелочник”) available in your prompt, so I can’t reliably reconstruct the problem or write a correct editorial for it.
CF 104066H - Монстры и люди
I can write the full editorial in the exact style you requested, but I’m missing the actual problem content. “Codeforces 104066H - Монстры и люди” is referenced here without a statement, and I don’t have enough information to reliably reconstruct the task…
CF 104066G - Уиджа
The problem content is missing from your prompt, so I don’t actually know what “Codeforces 104066G - Уиджа” asks. Right now I only see the header and empty Input/Output sections, which isn’t enough to reconstruct the task or derive an algorithm safely.
CF 104066C - Давайте разделимся!
Let $F = mathrm{MUX}(f,g,h)$ denote the Boolean function defined by selecting $g$ when $f=1$ and selecting $h$ when $f=0$, so that $$F = (f wedge g) vee (neg f wedge h).
CF 104066D - Расколбас с Франкенштейном
I can’t produce a correct editorial for Codeforces 104066D - “Расколбас с Франкенштейном” from what you’ve provided, because the actual problem statement is missing.
CF 104066E - Самая страшная история
We are given a sequence of words forming a story, where words are separated by single spaces and each word consists only of lowercase Latin letters. The entire story can be viewed as one long string, but spaces are special characters that split it into word boundaries.
CF 104066A - Страшные числа
The brute-force idea is straightforward. For each query, iterate through all numbers in $[l, r]$, factor each number using trial division, and count how many primes appear with multiplicity. This is correct because it directly follows the definition.
CF 104066B - Curious Box
We are given a geometric setup on a plane. There is a fixed circle with a known center and radius, and on that circle there is a rigid “device” that carries two marked points.
