What happens in a stack when a new element is pushed?

When a new element is pushed onto a stack, it is added to the top of the stack. Stacks are designed to follow the Last In, First Out (LIFO) principle, meaning that the last element added to the stack is the first one to be removed. By adding the new element to the top, it becomes the most accessible item, ready for retrieval or removal in future operations.

This operation ensures that each push action maintains the structure of the stack and allows easy access to the most recently added elements. The stack effectively manages its contents by layering each new addition on top of the previous one, creating a stack-like structure. This characteristic is crucial for various applications, such as parsing expressions or managing function calls in programming languages.
