During the infix to postfix conversion of the expression 'A+B*C-D/E', which operator would be pushed onto the stack first?
/
In a stack implemented using a linked list, where does the 'push' operation add the new element?
At the beginning of the linked list.
At the end of the linked list.
At a specific index in the linked list.
It depends on the data being inserted.
What is the primary disadvantage of implementing a stack using a fixed-size array?
Higher memory usage compared to dynamic arrays
Complex implementation requiring advanced pointer manipulation
Inability to handle stacks larger than the predetermined size
Increased time complexity for push and pop operations
If you represent an arithmetic expression in postfix notation using a stack, what operation would you perform when encountering an operand (a number)?
Check if the stack is empty.
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.
What is a potential drawback of using a linked list-based stack compared to an array-based stack?
Limited stack size
Higher memory usage due to the overhead of storing pointers
Inability to handle dynamic resizing
Which of the following stack operations has a time complexity of O(1) in both array-based and linked list-based implementations?
All of the above
Pop
Peek
Push
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 doubly linked list
Stack using a fixed-size array
Stack using a dynamic array
Stack using a singly linked list
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
Circular linked list
Doubly linked list
Both singly and doubly linked lists are equally efficient.
Which real-life scenario most accurately reflects the LIFO (Last In First Out) principle of a stack data structure?
A queue of people waiting for a bus.
A list of tasks sorted by priority.
A tree of files and folders on a computer.
A stack of plates on a table.
In a stack implemented using a singly linked list, which end of the list typically represents the top of the stack?
Middle
Tail
Head
It can be either the head or the tail, depending on the implementation.
