/// The is_consecutive function
///
/// heck whether a stack contains a sequence of consecutive integers starting from the bottom. Two approaches are provided: one using an auxiliary stack, and one using an auxiliary queue.
///
/// # Examples
///
/// Basic usage:
/// ```
/// let result = algorithmz::stack::is_consecutive(vec![3,4,5,6,7]);
/// assert_eq!(result, true);
/// ```
