What is Stack?

Stack is a powerful Abstract Data Type (ADT) that follows the Last-In-First-Out (LIFO) principle and allows dynamic data handling.

* Abstract Data Type (ADT):
A logical model, not concerned with how it’s implemented — only what it does (e.g., push, pop, peek).

* LIFO (Last-In-First-Out):
The most recently added element is the first one to be removed — like a stack of plates.

* Dynamic Nature:
Though it can be implemented using static arrays, stacks can also grow/shrink using dynamic memory (linked list or STL).

Galileo Galilei is known as the “father” of observational astronomy, modern physics, the scientific method and modern science.

Galileo was an Italian engineer, physicist and astronomer. He was the inventor of the thermoscope (a device that shows the changes in temperature) and various military compasses.

He used the telescope for scientific observations of celestial bodies.

Galileo was not agreed with the “Geocentric Model” of Ptolemy and advocated the astronomical model “Copernican Heliocentrism” by Nicolaus Copernicus published in 1543 that stated the Sun’s position at the center of the universe and .
