CF 105491B - K Palindrome
I don’t have the actual problem statement for Codeforces 105491B - K Palindrome, so I can’t safely reconstruct the editorial without risking inventing details that might be wrong. Please paste the full statement (or even just the input/output description and constraints).

Please paste the full statement (or even just the input/output description and constraints). Once you do, I’ll write the complete Codeforces-style editorial in the format you specified, including the walkthrough, proof sketch, code, and tests.
