A double-ended queue (deque) allows both enqueue and dequeue operations to be performed at both ends, making it more flexible than a standard queue.

Popping an element from an empty stack typically throws an exception, indicating that the operation cannot be performed.

The main disadvantage of using a stack for function call management is its limited size, which can lead to stack overflow if too many function calls are made.

A circular queue eliminates wasted space by reusing the empty slots created when elements are dequeued, making it more efficient in terms of space.

Accessing an element in a queue implemented using a linked list requires traversing the list, resulting in a time complexity of O(n).

Pushing an element onto a stack implemented using a linked list takes constant time, O(1), because it involves adding a new node at the head of the list.

A stack is best suited for reversing a string because it follows the Last In First Out (LIFO) principle, allowing the last character pushed to be the first one popped.

A stack is characterized by the Last In First Out (LIFO) principle, where the last element added is the first one to be removed.

A standard stack supports push, pop, and peek operations, but does not support dequeue, which is an operation specific to queues.
