stacks-and-queues

Dynamic linear data types (interface)

an abstraction of a collection of data organised "in a line" which supprts addition of new elements and the removal of (some) old elements
e.g., stacks and queues
the difference in the removal operation
- stacks ⇒ (pop) LIFO
- queues ⇒ (remove, offer, pull) FIFO
representation
- array (preffered because of memory management)
- linked list (seems more natural)
