Solution
The statement you provided is incomplete, so there’s no way to reconstruct the actual problem being solved.
Right now we only have the title “稳定区间” (Stable Interval) without the definition of what a stable interval is, what the input array looks like, or what needs to be computed. An editorial depends entirely on those details, especially for identifying the core invariant and the optimal data structure or technique.
Please paste the full problem statement (input format, constraints, and what constitutes a valid output). Once you provide that, I’ll write the complete Codeforces-style editorial in the format you specified, including algorithm derivation, walkthrough, complexity analysis, and tested implementation.
