Which data structure is most closely related to the concept of recursion?
Tree
Stack
Queue
Linked List
If you implement a stack using a dynamically allocated array, what is the time complexity of pushing an element in the worst-case scenario if you need to resize the array?
O(n log n)
O(n)
O(1)
O(log n)
What happens when you try to 'pop' an element from an empty stack?
The program crashes.
It depends on the specific implementation of the stack.
A special value (like -1) is returned.
A random element from the stack is removed.
If you implement a stack using an array, what problem might you encounter if you keep pushing elements onto the stack without any limit?
Memory Leak
Segmentation Fault
None of the above
Stack Overflow
Why is it generally more efficient to check if a stack is empty before popping an element?
It doesn't make a significant difference in terms of efficiency.
To avoid unnecessary computations within the pop operation.
To ensure the stack pointer is correctly updated.
To prevent potential errors or exceptions if the stack is empty.
Which data structure would be most suitable for implementing a Last-In-First-Out (LIFO) access pattern?
Heap
Deque
How does a stack help in implementing the undo functionality in text editors?
By storing a queue of actions.
By hashing the content.
By storing a stack of states.
By using a linked list of characters.
Which of these is NOT a typical application of stacks?
Storing data in a priority-based order
Managing function calls in a program's execution
Evaluating mathematical expressions (postfix notation)
Undo/Redo functionality in text editors
How does a stack help in converting infix expressions to postfix?
By reversing the order of operands
By directly translating the expression
By eliminating the need for parentheses
By prioritizing operators based on precedence
In a web browser, navigating back from a webpage utilizes which stack operation?
Peek
Push
Pop
IsEmpty
