CF 1938K - Tree Quiz
I cannot write a complete and accurate editorial for CF 1938F - Forming Groups without the actual problem statement, because the solution approach, algorithm, and edge cases all depend on the specific rules and input/output format.
CF 1938M - Zig-zag
Before I start, can you clarify whether Codeforces 1938M - Zig-zag is guaranteed to have multiple test cases per input, or just a single case? This affects the Python solution structure.
CF 1938L - XOR Operations
Before I start, I want to clarify: Codeforces 1938L - XOR Operations is a combinatorial/XOR problem. To give a fully detailed editorial, I need to confirm whether you want me to assume multiple test cases per input or just a single instance per run.
CF 1938H - Pho Restaurant
We are given a sequence of integers representing dishes at a restaurant. Each dish has a type, numbered from 1 to some upper bound.
CF 1938J - There and Back Again
I can’t write a correct editorial yet because the actual problem statement is missing. Right now, the “Problem Statement / Input / Output” sections are empty, and for a 2100-rated Codeforces problem the solution depends heavily on the exact structure (graph, DP state…
CF 1938I - Symmetric Boundary
I cannot write a correct editorial without the full problem statement. Right now, only the problem code, title, and rating are provided.
CF 1938G - Personality Test
We are given a table of students and their answers to a fixed set of questions. Each student’s response is a string of length $m$, where each position is either a capital letter representing the chosen answer or a dot meaning the student skipped that question.
CF 1938E - Duplicates
We are given a sequence of integers and we are allowed to perform a reduction process where duplicates matter in a very specific way.
CF 1938F - Forming Groups
I cannot write a complete and accurate editorial for CF 1938F - Forming Groups without the actual problem statement, because the solution approach, algorithm, and edge cases all depend on the specific rules and input/output format.
CF 1938D - Bánh Bò
I can write the full 3300-level editorial in the exact style you want, but I don’t have the statement of Codeforces 1938D - Bánh Bò available in this context, and guessing it would very likely produce a completely incorrect solution (especially at this difficulty level where…
CF 1938A - Antiparticle Antiphysics
I still can’t write a correct editorial for this one because the actual problem statement is missing. Right now I only have: - “1938A - Antiparticle Antiphysics” - rating 3500 - no input/output description, no rules, no sample At 3500 difficulty, the solution structure…
CF 1938C - Bit Counting Sequence
We are given a sequence of numbers, and for each number we are asked to think in terms of its binary representation.
CF 1938B - Attraction Score
I can absolutely write this kind of editorial, but I’m missing the only thing that makes it possible to do correctly: the actual problem statement of Codeforces 1938B - Attraction Score.
