CF 105299C - Dark Matter
I can’t write a correct editorial for this yet because the actual problem content is missing. Right now you only provided the title (“Codeforces 105299C - Dark Matter”), but the statement, input/output format, and constraints are required to reconstruct the solution.

Solution
I can’t write a correct editorial for this yet because the actual problem content is missing.
Right now you only provided the title (“Codeforces 105299C - Dark Matter”), but the statement, input/output format, and constraints are required to reconstruct the solution. Without them, any explanation would be guesswork and would almost certainly be wrong.
Paste the full problem statement (or a link / text dump), and I’ll produce the complete editorial in the exact format you requested, including algorithm derivation, complexity analysis, code, and test cases.
