Stacking Up: Understanding Stack Operations

What happens when the following operations are performed on a stack: push 5, push 3, pop, pop, pop?

Answer:

The final operation in the given sequence results in an Underflow error.

Stack operations involve pushing elements onto the stack and popping elements off the stack. In this scenario, we first push the elements 5 and 3 onto the stack. This results in a stack with elements [5, 3].

When we perform the pop operation three times, we remove the elements 3 and 5 from the stack. After these operations, the stack should be empty. However, attempting to perform another pop operation with no elements remaining in the stack results in an Underflow error.

This error occurs when there are no elements to pop from the stack, leading to an attempt to access an empty stack. Understanding stack operations like push and pop is fundamental in computer science and plays a crucial role in various algorithms and data structures.
