Explain the significance of the top pointer in a stack data structure.
- Keeps track of the current size of the stack.
- Maintains the sum of all elements in the stack.
- Points to the first element in the stack.
- Points to the last element in the stack.
The top pointer in a stack data structure points to the last element added to the stack. This pointer is crucial for efficient push and pop operations, allowing easy access to the most recently added element, ensuring constant time complexity for these operations.
