CF 103993G - Scoring
Let $G = (V,E)$ denote the contiguous-USA graph of (18), and let $U subseteq V$. The induced subgraph $G mid U$ is bipartite if and only if it contains no cycle of odd length, equivalently if and only if every connected component of $G mid U$ admits a 2-coloring.
CF 103993M - Antifibonacci Cut
I can’t write a correct editorial for “Antifibonacci Cut” without the actual problem statement. Right now the task only contains metadata, but none of the essential details like what the input represents, what “cut” means, what constraints are, or what defines an…
CF 103993L - Intersection and Union
The problem statement for Codeforces 103993L - Intersection and Union is not included in your prompt, so there is no way to correctly reconstruct the intended task, constraints, or required output.
CF 103993K - FTL
I can’t reliably write an editorial for Codeforces 103993K - FTL because the actual problem statement (inputs, outputs, constraints, and rules) isn’t included in your prompt.
CF 103993J - Problem with Random Tests
The problem statement for “Codeforces 103993J - Problem with Random Tests” is not included in your prompt, so there is no way to reconstruct the algorithm, constraints, or even the required task from the information given.
CF 103993I - Lanterns
I can write the full editorial, but the problem statement for Codeforces 103993I - Lanterns is missing from your prompt. Right now I don’t know: - what the lanterns represent, - what the input describes, - what operation or optimization is required, - what needs to be computed.
CF 103993H - Report Preparation
I don’t have the actual problem statement for Codeforces 103993H - Report Preparation, so I can’t produce a correct editorial yet. Right now the prompt only contains the template, but no description of what the input represents, what needs to be computed, or any constraints.
CF 103993E - d-Sort
I don’t have the actual problem statement for Codeforces 103993E - d-Sort, so I can’t reliably derive the algorithm, constraints, or edge cases needed for a correct editorial.
CF 103993F - Save the Magazines
I’m missing the actual problem statement for Codeforces 103993F - Save the Magazines, so I can’t reliably reconstruct the model or write a correct editorial.
CF 103993D - Password
We are dealing with 6-digit passwords, where each password is a sequence of digits from 0 to 9. The structure of the password is highly constrained: it must use exactly two distinct digits, and each of those digits must appear exactly three times, so the password is always a…
CF 103993C - Reverse and Remove
I’m missing the actual problem statement for Codeforces 103993C - Reverse and Remove, so I can’t reliably reconstruct the intended solution or write a correct editorial.
CF 103993A - As Fast As Possible
The level is modeled as an infinite number line. A character starts at position 0 and wants to reach position n. At each moment, the character can either move one unit left or right, paying a fixed cost a seconds per unit step, or perform a teleport-like jump that moves…
