During the infix to postfix conversion of the expression 'A+B*C-D/E', which operator would be pushed onto the stack first?

How are stacks utilized in syntax parsing within compilers?
To check for matching parentheses, braces, and brackets.
For storing the symbol table of variables.
For performing code optimization.
To generate intermediate code during compilation.
What is a potential drawback of using a linked list-based stack compared to an array-based stack?
Inability to handle dynamic resizing
Higher memory usage due to the overhead of storing pointers
Increased time complexity for push and pop operations
Limited stack size
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 dynamic array
Stack using a singly linked list
Stack using a fixed-size array
What is the primary role of a stack in expression evaluation?
Converting infix expressions to postfix.
Storing the variables used in the expression.
Evaluating the precedence of operators.
Performing arithmetic calculations on operands.
What is the result of evaluating the prefix expression '-+5*234'?

How do stacks facilitate backtracking in algorithms?
By providing a mechanism for parallel processing.
By storing the optimal solution found so far.
By optimizing the search space for the algorithm.
By maintaining a record of visited states and enabling the algorithm to revert to previous states.
In a stack implemented using a linked list, where does the 'push' operation add the new element?
At a specific index in the linked list.
At the end of the linked list.
At the beginning of the linked list.
It depends on the data being inserted.
What is the purpose of the 'top' pointer in an array-based stack implementation?
To store the maximum size of the stack
To store the value of the top element in the stack
To track the index of the next available position for insertion
To point to the bottom element of the stack
Which of the following operations is NOT typically associated with a Deque?
peek (view the element at the front without removing)
push (insert at the rear)
inject (insert at the front)
pop (remove from the rear)
