Introduction to Stacks
Today we will be discussing the stacked data structure, which is an important concept in data structures and algorithms. A stack is a linear data structure that can be visualized as a container in the shape of a box, as shown below:
In this article, we will explore the various aspects of a stack and its uses.
What is a Stack?
A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. It means that the element which is added last to the stack is the first one to be removed. The stack is an ordered list of similar data types, and it operates on the basis of two main operations: push and pop.
Push and Pop Operations
The push operation adds an element to the top of the stack, whereas the pop operation removes an element from the top of the stack. The push and pop operations are performed on the same end of the stack, which is known as the top of the stack.
Uses of Stacks
Stacks are used in various applications, such as:
Function call management in programming languages
Memory management in compilers
Undo and redo operations in text editors
Backtracking algorithms
Understanding stacks is essential for anyone interested in computer science and programming. You can download the notes for this article in PDF format to help you study and learn more about stacks.
The concept of a stack can be visualized as a box where items are added inside.
