CF 105818L - Can you Count?

You are right to pause here: there is a problem with the prompt itself. “Codeforces 105818L - Can you Count?” is not a standard public problem with a reliably accessible statement in the usual Codeforces problemset or gym archive naming scheme, and the information needed…

CF 105818K - Bocchi the Tour

I can write this editorial, but I need the actual problem statement details beyond the title and constraints to avoid inventing a solution.

CF 105818I - Permutation Online

We are given a permutation of size $N$. As we scan positions from left to right, each position $i$ looks back at earlier positions and considers only those earlier indices $k < i$ whose permutation value is larger than the current value $pi$.

CF 105818J - Triangle Constructive

We are working inside a triangular grid defined by coordinates $(x, y, z)$ where all three are non-negative and always satisfy $x + y + z = N$.

CF 105818E - Robot Racing

We have robots arranged in a non-decreasing order of speed. For every contiguous segment of robots, we want to know the maximum number of groups they can be split into so that each group can be stopped at a different second before any robot leaves the track.

CF 105818H - Permutation Composition

I can’t reliably write a correct editorial for this problem as-is because the actual problem statement is missing from your prompt.

CF 105818G - Binary Function II

I’m missing the actual problem statement for Codeforces 105818G - Binary Function II (the “Problem Statement / Input / Output” sections are empty in your prompt).

CF 105818F - Binary Function

I can't write a correct editorial for Codeforces 105818F - Binary Function from the information provided here because the actual problem statement, input format, and constraints are missing.

CF 105818D - Not Japanese Triangle

We are given only the bottom row of a triangular number structure. Above it, each row is formed from the row directly below using a very specific rule: every cell is the minimum of its two children beneath it.

CF 105818B - Cell Towers

Each house is located at a grid position $(r,c)$. A tower placed at $(R,C)$ covers every house satisfying $$C le c$$ and $$r+c le R+C.$$ The cost of that tower is simply $R$, its row.

CF 105818A - Lily Pads

We have a pond with N rows of lily pads. Each row contains two possible landing positions, left and right. At any moment, exactly one side of a row is above water and can be used. Two frogs start before the first row and both need to cross the pond. A frog always moves forward.

CF 105818C - Walk

I don’t have the statement of Codeforces 105818C - Walk available in the prompt, and I can’t reliably reconstruct it from the title alone without risking inventing the wrong problem.
