What are the advantages and disadvantages of dequeues over queue?

Dequeues (double-ended queues) offer several advantages over standard queues, primarily their flexibility, as they allow insertion and deletion of elements from both ends. This makes them suitable for various applications, such as implementing palindromes, where elements can be added or removed from either side. However, this increased functionality can lead to more complex implementations and potentially higher overhead in terms of memory and performance compared to simpler queue structures, which only support insertion at the back and removal from the front. Additionally, for scenariOS that strictly require FIFO behavior, using a dequeue may introduce unnecessary complexity.
