Hello 演算法 Rust 語言版 作者：靳宇棟（@krahets） 程式碼審閱：伍志豪（@night‑cruise）、榮怡（@rongyi） Release 1.2.0 2024‑12‑06 序 兩年前，我在力扣上分享了“劍指 Offer”系列題解，受到了許多讀者的鼓勵與支持。在與讀者交流期間，我 最常被問到的一個問題是“如何入門演算法”。漸漸地，我對這個問題產生了濃厚的興趣。 位元組。 ‧ Go 語言的 string 型別在內部使用 UTF‑8 編碼。Go 語言還提供了 rune 型別，它用於表示單個 Unicode 碼點。 ‧ Rust 語言的 str 和 String 型別在內部使用 UTF‑8 編碼。Rust 也提供了 char 型別，用於表示單個 Unicode 碼點。 需要注意的是，以上討論的都是字串在程式語言中的儲存方式，這和字串如何在檔案中儲存或在網路中傳輸 0, 0, 0, 0] let slice: &[i32] = &[0; 5]; // 在 Rust 中，指定長度時（[i32; 5]）為陣列，不指定長度時（&[i32]）為切片 // 由於 Rust 的陣列被設計為在編譯期確定長度，因此只能使用常數來指定長度 // Vector 是 Rust 一般情況下用作動態陣列的型別 // 為了方便實現擴容 extend() 方法，以下將 vector

Note that events may be coalesced, so multiple calls to uv_async_send may result in a single wakeup notification to the condition. 28.17 More About Callbacks For more
