Which type of linked list allows for more efficient push and pop operations at both ends, making it suitable for implementing a stack?
Both singly and doubly linked lists are equally efficient.
Circular linked list
Doubly linked list
Singly linked list
Which of the following stack operations has a time complexity of O(1) in both array-based and linked list-based implementations?
Push
All of the above
Peek
Pop
Which real-life scenario most accurately reflects the LIFO (Last In First Out) principle of a stack data structure?
A tree of files and folders on a computer.
A queue of people waiting for a bus.
A stack of plates on a table.
A list of tasks sorted by priority.
If you represent an arithmetic expression in postfix notation using a stack, what operation would you perform when encountering an operand (a number)?
Ignore the operand.
Check if the stack is empty.
Pop the top two elements from the stack, perform the operation, and push the result back onto the stack.
Push the operand onto the stack.
In a linked list-based stack implementation, what does the 'isEmpty()' operation typically check?
If the tail pointer is pointing to NULL
If the stack has reached its maximum capacity
If the stack contains any elements with a value of zero
If the head pointer is pointing to NULL
What is the primary difference between 'pop' and 'peek' operations on a stack?
'Pop' is used for stacks, while 'peek' is used for queues.
'Pop' retrieves the top element's value, while 'peek' removes it from the stack.
'Pop' and 'peek' are interchangeable terms for the same operation.
'Pop' removes the top element, while 'peek' only retrieves its value without removing it.
Imagine a stack is used to track function calls in a recursive program. What happens to the stack when a function returns?
The stack remains unchanged.
The corresponding function call is popped from the stack.
The corresponding function call is pushed onto the stack.
The entire stack is cleared.
Consider the scenario of undoing actions in a text editor. Which data structure would be most suitable for implementing an 'undo' feature?
Linked List
Binary Tree
Queue
Stack
Which of the following operations is NOT typically associated with a Deque?
push (insert at the rear)
peek (view the element at the front without removing)
pop (remove from the rear)
inject (insert at the front)
What is a potential drawback of using a linked list-based stack compared to an array-based stack?
Higher memory usage due to the overhead of storing pointers
Inability to handle dynamic resizing
Limited stack size
Increased time complexity for push and pop operations
