Solution

The problem statement for Codeforces 103643E - “Oops, It’s Yesterday Thrice More!” is not included in your prompt, so there’s no way to correctly reconstruct the solution or write a meaningful editorial yet.

For Codeforces editorials, the actual statement is essential because even small differences in interpretation (for example, whether we are dealing with strings, graphs, intervals, or modular arithmetic) completely change the algorithm. Without it, any attempt to proceed would be guesswork rather than an explanation you can rely on.

If you paste the full statement (or even just the input/output description and constraints), I can produce a complete, structured editorial in the exact format you requested, including intuition, derivation, complexity analysis, and a full reference implementation.
