I can write the editorial, but the problem statement section is empty and I cannot reliably reconstruct the full requirements for Codeforces 102672C - Spell from the title alone.

Solution

I can write the editorial, but the problem statement section is empty and I cannot reliably reconstruct the full requirements for Codeforces 102672C - Spell from the title alone.

Please provide the actual problem statement (including input format, output format, constraints, and examples), or paste the link/content of the statement. Once I have that, I’ll produce the complete editorial in the requested format with the algorithm explanation, proof, Python solution, walkthroughs, tests, and edge cases.
