Which of the following operations is NOT typically associated with a Deque?
pop (remove from the rear)
peek (view the element at the front without removing)
inject (insert at the front)
push (insert at the rear)
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 singly linked list
Stack using a doubly linked list
During the infix to postfix conversion of the expression 'A+B*C-D/E', which operator would be pushed onto the stack first?

In maze-solving algorithms, how does the use of a stack differ between depth-first search (DFS) and breadth-first search (BFS)?
DFS uses a stack only if the maze is solvable, while BFS always uses a queue.
DFS uses a stack to explore as deeply as possible before backtracking, while BFS uses a queue to explore all neighbors at a given level.
BFS uses a stack to prioritize unexplored paths, while DFS uses a queue to systematically explore all directions.
Both DFS and BFS use stacks identically; the difference lies in how they mark visited nodes.
In a stack implemented using a linked list, where does the 'push' operation add the new element?
At the end of the linked list.
It depends on the data being inserted.
At the beginning of the linked list.
At a specific index in the linked list.
If you represent an arithmetic expression in postfix notation using a stack, what operation would you perform when encountering an operand (a number)?
Ignore the operand.
Push the operand onto the stack.
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.
How are stacks utilized in syntax parsing within compilers?
For storing the symbol table of variables.
To generate intermediate code during compilation.
To check for matching parentheses, braces, and brackets.
For performing code optimization.
What is the result of evaluating the prefix expression '-+5*234'?

What is the primary difference between 'pop' and 'peek' operations on a stack?
'Pop' is used for stacks, while 'peek' is used for queues.
'Pop' retrieves the top element's value, while 'peek' removes it from the stack.
'Pop' and 'peek' are interchangeable terms for the same operation.
'Pop' removes the top element, while 'peek' only retrieves its value without removing it.
Which type of linked list allows for more efficient push and pop operations at both ends, making it suitable for implementing a stack?
Both singly and doubly linked lists are equally efficient.
Circular linked list
Doubly linked list
Singly linked list
