Queue is a data structure that implements a FIFO (first-in first-out) ordering upon which the following operations are supported:

  • add(object): add object at the end of the queue O(1)
  • remove(): remove the object which at the beginning of the stack O(1)
  • peek(): return object which is at the beginning of the stack O(1)

A queue can be used in BFS or to implement a cache.
