CF 103109G - Scribble Roads

For real $x ge t-1$, define the generalized binomial coefficients $$binom{x}{t} = frac{x(x-1)cdots(x-t+1)}{t!}, qquad binom{x}{t-1} = frac{x(x-1)cdots(x-t+2)}{(t-1)!}.

CF 103109L - Pillar Path

I can write the full editorial in the exact format you requested, but I’m missing the actual problem statement.

CF 103109K - Kirby's Buffet

I don’t have the actual statement of Codeforces 103109K - Kirby's Buffet, so I can’t safely reconstruct the logic or write a correct editorial without guessing.

CF 103109J - Luigi's Mansion

The problem statement is missing from your prompt, so I don’t have enough information to write a correct editorial.

CF 103109I - Immortality Potion

I can’t write a correct Codeforces editorial for “103109I - Immortality Potion” because the actual problem statement is missing from your prompt.

CF 103109H - Future Gadget Lab

The problem statement for Codeforces 103109H - Future Gadget Lab is missing from your prompt, so there is no way to reconstruct the intended task, constraints, or solution correctly.

CF 103109E - Knockout Tournament

I can’t write a correct editorial for this yet because the actual problem statement is missing. “Codeforces 103109E - Knockout Tournament” isn’t enough on its own to reconstruct the rules, and anything I write without the full description would be guesswork (which would…

CF 103109A - Pokémon Permutation

Let $kappat$ be the function defined in the section, with inverse $mut$ in the sense that $$M ge mut N quad Longleftrightarrow quad kappat(M) ge N,$$ for $t ge 2$.

CF 103109F - Squid Art

The problem statement is missing, so I can’t reliably reconstruct what Codeforces 103109F “Squid Art” is asking or derive a correct solution.

CF 103109D - Cytus Craze

The problem statement section is empty, so there is no way to reconstruct what “Cytus Craze” is asking us to compute. Without knowing the input format, the rules, or what constitutes a valid answer, any editorial would be pure invention rather than explanation.

CF 103109C - Goomba Grouping

I cannot reliably reconstruct Codeforces 103109C - Goomba Grouping from the available context or standard archives, and the statement is not present in the prompt.

CF 103109B - Azran Tablets

The problem statement section is empty, so I don’t actually have the definition of what “Azran Tablets” is asking us to compute. Without that, I can’t write a correct editorial, because everything from the solution strategy to the edge cases depends on the exact rules.
