In a stack, how is the element that was added before the last added element accessed?
Directly using its index.
By searching the entire stack sequentially.
By popping the top element first.
It's not possible to access elements directly in a stack.
Which of the following is a significant drawback of implementing a stack using a static array?
Fixed size limitation
Slow push and pop operations
High memory usage
Complex implementation
What is the time complexity of pushing an element onto a stack implemented using a static array, assuming there is enough space?
O(log n)
O(n log n)
O(1)
O(n)
Why is it generally more efficient to check if a stack is empty before popping an element?
To avoid unnecessary computations within the pop operation.
To prevent potential errors or exceptions if the stack is empty.
It doesn't make a significant difference in terms of efficiency.
To ensure the stack pointer is correctly updated.
What value does the 'peek' operation return if the stack is empty?
0
It depends on the implementation.
null
-1
How does a stack help in implementing the undo functionality in text editors?
By storing a stack of states.
By using a linked list of characters.
By storing a queue of actions.
By hashing the content.
How does a stack implemented using a linked list handle overflow compared to an array-based implementation?
Linked list implementation avoids overflow as long as memory is available.
Linked list implementation prevents overflow by overwriting existing elements.
Linked list implementation also suffers from overflow.
Both implementations handle overflow similarly.
What is the primary advantage of using a linked list to implement a stack over an array?
Faster push and pop operations
Lower memory usage
Simpler implementation
Dynamic resizing capability
In the context of memory allocation within a program, what type of stack is used?
Queue
Call Stack
Heap
Linked List
What is the time complexity of pushing an element onto a stack implemented using a linked list, assuming the push operation is implemented efficiently?
