/// Is Rotated String
///
/// Given two strings, determine if the second is a rotated version of the first. Two approaches are provided: concatenation check and brute force.
///
/// # Examples
///
/// Basic usage:
/// ```
/// let result = algorithmz::string::is_rotated("hello", "llohe");
/// assert_eq!(result, true);
/// ```
