The task describes a zoo where animals are grouped into several kinds, and each kind has a known number of individual animals. The input gives a list where each value corresponds to how many animals belong to one specific kind.

I can’t responsibly write the full editorial yet because the actual problem statement for Codeforces 105940E - Kilani The Tiger (Easy) is not available in your prompt and it is not reliably accessible from the contest listing alone.

This problem asks us to work on an undirected, unweighted graph that represents the paths inside a zoo. Some vertices contain zebra enclosures. For every vertex, we need the shortest number of edges needed to reach any vertex containing a zebra enclosure.

The problem statement section is empty, so I don’t have the actual task (inputs, outputs, or rules). Without that, I can’t produce a correct editorial or derive any algorithmic solution.

I’m missing the actual problem statement, and for Codeforces tasks that makes it impossible to write a correct editorial without guessing.

I cannot reliably reconstruct the full problem statement of Codeforces 105947D - “Bảo và các triết gia” from the title alone, and it is not present in the provided prompt.

You’re right to expect a proper editorial here, but there is a problem upstream: the statement for Codeforces 105947A - Truyền tin is not present in the prompt, and it does not correspond cleanly to any standard Codeforces archive problem available from the 1059xxx range in…

The problem statement is missing, so there isn’t enough information to write a correct editorial. Codeforces problems with only a title like “Noisy Cat” don’t provide enough structure to reconstruct the intended task, constraints, or solution approach.

I can’t reliably write a correct Codeforces editorial for this because the actual problem statement is missing. Right now I only see the title “1059614 - D. Настолка”, but no description of the rules, input format, or required output.

The task is to divide the given numbers into two groups. A pair of numbers receives its normal sum if both numbers are placed in the same group, but receives an additional penalty h if the two numbers are separated.

The problem describes a point moving inside a right isosceles triangle with vertices at (0,0), (0,n), and (n,0). The point starts at (x,y) and moves with velocity (vx,vy). When it touches a side of the triangle, it reflects like a ray of light.

I can write the full editorial in the exact structure you want, but I’m missing the only thing required to do it correctly: the actual problem statement.

The graph is directed and acyclic in a very strong sense: every edge goes from a smaller-numbered vertex to a larger-numbered one.

I can’t write a correct Codeforces editorial for “105971K - Test Task” without the actual problem statement. Right now the input/output and constraints are completely missing, so any attempt to “fill it in” would just be guessing and would produce a fake solution.

I can write the full editorial in that format, but the problem statement is missing. I could not identify Codeforces 105971I - B'obr reliably from the title alone, and I do not want to invent an algorithm, constraints, or samples.

I’m missing the actual problem statement for Codeforces 105971H - Vadim’s Collection, so I can’t reliably write a correct editorial yet.

We are given a sequence of pairs. Each pair consists of a position value and a weight. We process the sequence incrementally: after the first element, after the first two elements, and so on up to the full sequence.

The tournament has n teams. Every pair of teams plays once, and the probability that team i defeats team j depends only on their strengths: the stronger team is more likely to win, but either result is possible.

I can write the editorial, but I need one clarification first: Codeforces 105993E has a constructive output (a sequence of operations), and a complete editorial depends on the exact accepted construction.

I can’t produce a correct, meaningful editorial for this problem as written because the actual problem statement is missing.

We are given a graph where cities are connected by undirected roads, and each road connects two different cities. The task is to determine the length of the shortest simple cycle in this graph.

The problem gives two proposed swimming times from two judges. Each judge suggests an integer moment when they want to go swimming, and the final decision is to choose the earliest possible moment so they can still attend the contest. The task is to output that earliest time.

I can absolutely write this in the requested editorial style, but I’m missing the actual problem statement for Codeforces 105993A - Olives and Water. Right now, the prompt only includes headers without any description of the task, input/output format, or constraints.
