CF 103274C - Cypher Decypher
I can’t write a correct editorial yet because the actual problem statement is missing. Right now I only know the title “Cypher Decypher”, but there’s no description of the input format, constraints, or what transformation is required.

Solution
I can’t write a correct editorial yet because the actual problem statement is missing.
Right now I only know the title “Cypher Decypher”, but there’s no description of the input format, constraints, or what transformation is required. For Codeforces problems, those details completely determine the solution technique, and guessing would just produce a fabricated editorial.
Paste the full statement (or even a screenshot/text dump), and I’ll produce a complete, step-by-step editorial in the exact style you requested, including the algorithm derivation, proof idea, Python solution, worked traces, and edge-case analysis.
