AI translates the explanation and quiz text while preserving code and answer scoring.

`&str` is a borrowed immutable UTF-8 slice; `String` is an owned growable buffer. Convert with `to_string()` and borrow back via deref coercion. Byte indexing is disallowed because UTF-8 characters vary in width; use `.chars()` instead.

How to study this topic

  1. 1. Read the explanation once end to end, skipping the code.
  2. 2. Re-read the code snippets and say out loud what each line does.
  3. 3. Answer the quiz without scrolling back — that is the real check.
  4. 4. Read every explanation, even for the answers you got right.
