Compare different ways to implement the FIFO (First-In, First-Out) Queue data structure.
Simple queue using a fixed-size array. Shows the 'drifting' problem where space is lost.
Dynamic queue with O(1) ops and no capacity limit.
Optimized array implementation reusing empty spaces (Ring Buffer).
Generalized queue allowing insertion/deletion at both ends.
Implement LIFO behavior using two FIFO Queues.
Classic application of Deque to find max in linear time.
