If you represent an arithmetic expression in postfix notation using a stack, what operation would you perform when encountering an operand (a number)?
Push the operand onto the stack.
Ignore the operand.
Pop the top two elements from the stack, perform the operation, and push the result back onto the stack.
Check if the stack is empty.
Which type of linked list allows for more efficient push and pop operations at both ends, making it suitable for implementing a stack?
Singly linked list
Both singly and doubly linked lists are equally efficient.
Circular linked list
Doubly linked list
In a stack implemented using a linked list, where does the 'push' operation add the new element?
It depends on the data being inserted.
At the beginning of the linked list.
At a specific index in the linked list.
At the end of the linked list.
What is the time complexity of the 'peek' operation in a well-implemented stack?
O(log n)
O(1)
O(n log n)
O(n)
You need to implement a stack that can store a large number of items and the maximum number of items is unknown. Which implementation would be more suitable?
Stack using a fixed-size array
Stack using a dynamic array
Stack using a doubly linked list
Stack using a singly linked list
How are stacks utilized in syntax parsing within compilers?
For performing code optimization.
To generate intermediate code during compilation.
To check for matching parentheses, braces, and brackets.
For storing the symbol table of variables.
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)
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 entire stack is cleared.
The corresponding function call is popped from the stack.
The corresponding function call is pushed onto the stack.
During the infix to postfix conversion of the expression 'A+B*C-D/E', which operator would be pushed onto the stack first?
/
What is the purpose of the 'top' pointer in an array-based stack implementation?
To store the value of the top element in the stack
To store the maximum size of the stack
To track the index of the next available position for insertion
To point to the bottom element of the stack
