📝 概要

この期間の変更では、LeetCode の複数問題(14, 20, 21, 26)に対する多言語解説ドキュメント(Python, TypeScript, Go, Java, Rust, Dart, Kotlin, Swift, C++, C# 等)および React UI コンポーネントの追加・拡張が行われました。 また、言語固有の技術的仕様(メモリ割り当て、プロトタイプ汚染対策、エスケープ解析、型安全性など)に関する記述の精査や計算量表記の推敲、それに伴う Web 成果物(public/)の自動再生成が実施されています。


🔍 主な変更内容

1. LeetCode 問題解説・UIの追加および機能改善

  • LeetCode 14 (Longest Common Prefix):
    • 解答ドキュメントおよびインタラクティブな React UI の新規作成。
    • Go / TypeScript / Python 解説の更新および不要な React フックガードの削除。
  • LeetCode 20 (Valid Parentheses):
    • TypeScript におけるプロトタイプ汚染対策(Object.prototype.hasOwnProperty.call の採用)と型の絞り込み。
    • Java の Character キャッシュ動作の解説修正および Rust における BracketError の文字処理の統一。
    • Markdown のフォーマット修正(MD031 遵守)。
  • LeetCode 21 (Merge Two Sorted Lists):
    • Claude Sonnet 5 による多言語解説(Go, Java, Python, Rust, TS)および React UI の追加。
    • ダミーノードのヒープ割り当て戦略やメモリ構造の記述調整、見出し構造(H2/H3)とセクション番号の整理。
    • Dart, Kotlin, Swift ドキュメントの表現見直しおよび Go vs TypeScript の nullability(型安全性)に関する解説強化。
  • LeetCode 26 (Remove Duplicates from Sorted Array):
    • Sonnet 5 解説ドキュメントおよび React UI の追加。
    • C++, C#, TS, Go, Python ドキュメントの更新(エスケープ解析、変数カウント、エラーハンドリング、enumerate の記述修正)。

2. ドキュメント表現・計算量表記の精査

  • 計算量と技術解説のブラッシュアップ:
    • LeetCode 21 / 26 を中心に、時間・空間計算量の表記を統一し、文章全体の推敲を実施。
    • Kotlin における val 引数やローカル変数の再バインドに関する注釈修正など、各言語の挙動に関する記述を精確化。

3. ビルド基盤・成果物の同期

  • 成果物(public/)の自動生成:
    • 解説ドキュメントおよび UI の更新に合わせて、ジェネレータによる HTML / React コンポーネント生成スクリプトを実行し、public/ ディレクトリ配下を最新化。

Algorithm/TwoPointers/leetcode/26. Remove Duplicates from Sorted Array/Sonnet 5/Remove-Duplicates-from-Sorted-Array-Go.md (1)

29-29: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Go のメモリ配置を断定しないでください。

29行目と113〜115行目では、slowfastが必ずスタックに割り当てられると説明しています。Goは配置を保証しません。実際の配置はコンパイラのエスケープ解析と最適化に依存し、レジスタに保持される場合もあります。「通常はヒープへエスケープしない」と表現し、ヒープアロケーションが発生しないという断定も避けてください。

- Line 1104:
README内の空配列の言語別挙動説明を更新し、TypeScriptではnums[0]がTypeErrorではなくundefinedを返す記述に修正してください。1115行目の表と内容を一致させ、他言語の説明や既存のガード記述は変更しないでください。
- Around line 618-620: 「LeetCode
Class形式」付近のC++初心者向け補足を修正し、std::vector<int>&はコピーせず元のvectorを操作する参照であり、範囲チェック機能を持たないと説明してください。operator[]の範囲外アクセスは未定義動作であること、範囲チェックには.at()を使い、範囲外でstd::out_of_rangeを送出することも明記してください。
- Around line 1145-1147:
READMEのQ3にあるボクシング説明を修正し、C#をJava/Kotlinの説明から分離してください。C#のList<int>は値型を直接格納するため、利用だけではボクシングが発生しないと明記し、List<object>など値型を参照型へ変換する場合に限定して説明してください。

- Around line 13-15: Update the state-variable descriptions in
Remove-Duplicates-from-Sorted-Array-Go.md lines 13-15 and
Remove-Duplicates-from-Sorted-Array-Python.md lines 13-15 to state that the
Two-Pointer implementation uses two index variables, slow and fast, instead of
one; make no other changes.

non-list value raises TypeError. Keep the existing empty-list behavior returning
0 unchanged.

実装と矛盾する説明を修正してください。

Line [136-137] では、currentList1currentList2 をローカルの var に持ち替える必要がないと説明しています。しかし、Line [138-139] で実際にローカル変数を作成し、Line [152] と Line [156] で更新しています。説明を「ローカルの var に持ち替える必要がある」に修正してください。

修正例
- // ここではローカルの var として持ち替える必要はなく、- // 直接 while 内で条件式として使い続ける。+ // ここではローカルの var として持ち替え、+ // その変数を while 内で更新する。

- Line 16: Update the “CPython最適化” explanation in
Remove-Duplicates-from-Sorted-Array-Python.md to accurately state that
enumerate() provides both an index and value. Explain that range() is chosen
because the algorithm directly accesses nums[fast] and nums[slow], rather than
claiming enumerate() lacks the required index.
