# Simplify some of the code
# Use ArrayDeque instead of LinkedList for queue implementation

{quote}
Resizable-array implementation of the Deque interface. Array deques have no capacity restrictions;
they grow as necessary to support usage. They are not thread-safe; in the absence of external
synchronization, they do not support concurrent access by multiple threads. Null elements
are prohibited. This class is likely to be faster than Stack when used as a stack, and *faster
than LinkedList when used as a queue.*
