Which of the following is a significant drawback of implementing a stack using a static array?
Slow push and pop operations
Complex implementation
Fixed size limitation
High memory usage
What is the primary disadvantage of using stacks compared to other data structures?
Limited access to elements (only top)
High memory consumption
Inability to store duplicate elements
Slow insertion and deletion at the end
In depth-first search (DFS) algorithms, what role does the stack play?
Storing edge weights
Maintaining the order of node exploration
Storing visited nodes
Calculating shortest paths
What is the time complexity of pushing an element onto a stack implemented using a linked list, assuming the push operation is implemented efficiently?
O(1)
O(n log n)
O(log n)
O(n)
Which data structure is most similar to a deque in terms of functionality?

Which data structure is most closely related to the concept of recursion?

How does a stack help in implementing the undo functionality in text editors?
By hashing the content.
By storing a stack of states.
By using a linked list of characters.
By storing a queue of actions.
How does a stack help in converting infix expressions to postfix?
By reversing the order of operands
By directly translating the expression
By prioritizing operators based on precedence
By eliminating the need for parentheses
In the context of the 'Next Greater Element' problem, what does the term 'next greater' refer to?
The element that is both to the right and has a larger value.
The element that appears most frequently after the current element.
The element with the next highest value in a sorted order.
The element that is lexicographically greater.
In a stack, how is the element that was added before the last added element accessed?
By searching the entire stack sequentially.
Directly using its index.
It's not possible to access elements directly in a stack.
By popping the top element first.
