- PUSH(3)
- PUSH(2)
- POP(stack, item)

Options:
A) 4
B) 25
C) Empty Stack
D) 3

Answer: The topmost element of the stack after the given operations will be 4.

2. Question 2: Peter has an array with the values q[] = {1, 2, 3, 4, 4, 3, 5, 6, 1, 4}. How many elements have a frequency that is a prime number? (Note: 1 is not considered a prime number)

Options:
A) 2
B) 3
C) None
D) 5

Answer: Among the given elements, there are 3 elements (3, 5, and 6) with a frequency that is a prime number.

3. Question 3: When simulating a stack with a linked list, where should we place a new element?

Options:
A) At the head (beginning) of the linked list.
B) At the tail (end) of the linked list.
C) At any random position in the linked list.
D) At the middle of the linked list.

Answer: A new element should be placed at the head (beginning) of the linked list.

4. Question 4: Which algorithm is most suitable for finding the shortest path in a directed weighted graph with negative edge weights?

Options:
A) Dijkstra's algorithm
B) Bellman-Ford algorithm
C) Prim's algorithm
