It makes sense to align the `Debug` implementation for `Segtree` with `LazySegtree` #143 once the discussion is settled.

The `Debug` trait implementation might be better if it follows the format discussed in `FenwickTree` #145 to keep things consistent. Also, personally, I feel that it might be a bit...

I'd like to propose a few improvements to the current `Debug` implementation for `LazySegtree`. Currently, the fields `n`, `size`, and `log` are not displayed. I think it would be better...

Thank you! That certainly sounds like a better approach. By "both," do you mean both the output format similar to `Segtree` and `LazySegtree` and the format I proposed? Or do...

I see, that makes a lot of sense. The ASCII art-like representation seems really useful, though I do have some concerns about potential formatting issues. Also, I agree that using...

I'd like to share my current thoughts on the output format for the `Debug` implementation. Please note that my opinion has changed from when I originally opened this issue, as...

I agree with the suggestion to implement the `Clone` trait separately. I'm planning to create a new branch with only the `Clone` implementation committed and open a separate PR for...

Thank you. I've opened PRs that implement only the `Clone` trait for `FenwickTree` and the other structs. Once the `Clone`-related changes are merged, I plan to rebase the existing draft...

I unintentionally closed the previous draft PR by renaming its branch. Although the rebase was successful, the commit message still refers to the original implementation (including `Clone`), and the branch...

現状 difficulty が表示されていない問題について、`https://kenkoooo.com/atcoder/resources/problem-models.json` を確認したところ、 - `difficulty` は数値として記録されている - 一方で、`slope`, `intercept`, `variance` が `null` になっている という特徴が見られました。 最初に例として挙げられている ABC227-G だけでなく、最近の ABC428-G などについても同様です。 また、`atcoder-problems-frontend/src/interfaces/ProblemModel.ts` の `isProblemModelWithDifficultyModel` 関数は数年前から変更されておらず、`slope` / `intercept` が - プロパティとして存在しない（`Object.prototype.hasOwnProperty.call` 関数が...
