How can you implement a stack using arrays? What are the advantages and limitations of this approach?
- Implement a circular buffer to represent the stack.
- Use a queue to simulate stack behavior.
- Use an array to store elements and a separate variable to keep track of the top element.
- Utilize a linked list for storing elements with a pointer to the top node.
A stack can be implemented using arrays by maintaining an array to store elements and a variable (top) to keep track of the index of the top element. The advantages include simplicity and constant-time access to the top element. However, the limitation lies in the fixed size of the array and potential overflow/underflow issues.
