Solution
The problem statement is missing from your prompt, so I can’t reliably reconstruct the task or write a correct Codeforces-style editorial.
“CntSeq” (103999E) isn’t enough to infer the rules, constraints, or required output, and guessing would almost certainly produce a wrong solution and misleading explanation.
Please paste the full problem statement (or at least the Input/Output specification and constraints). Once you provide that, I’ll write the complete editorial in the exact style you requested.
