This blog provides an introductory overview of trees in data structures, covering their basic components, types, and applications, aimed at beginners to facilitate easy understanding and practical insights.


An overview of queues in data structures, explaining their FIFO principle and basic operations with a Python example, highlighting their practical significance.


Stacks are a Last In, First Out (LIFO) data structure, used for tasks like expression evaluation, function calls, and undo mechanisms, supporting operations like push, pop, and peek.

Linked Lists

Linked lists are a collection of nodes with data and references to other nodes, enabling efficient element addition and removal. Types include singly, doubly, and circular linked lists.


A concise guide on using classes for data structures and algorithms, illustrated through a stack implementation example.


This document explains Python's approach to pointer-like references and memory management, using examples like variable assignment and linked list implementation.

Big-O Notation

Introduction to Big-O Notation, a fundamental concept in computer science used for analyzing the efficiency of algorithms.

Python functions and methods

Functions A function in Python is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. Here’s how you can define a function: def greet(name): print(f"Hello, {name}!") And here’s how you can call it: greet("Alice") # Output: Hello, Alice! Functions can also return a value using the return statement: def add(a, b): return a + b result = add(5, 3) # result is now 8 Methods Methods in Python are very similar to functions except they are associated with object/classes....

Python control flow statements

Control flow statements in Python are used to control the order in which the program’s code executes. Here are some of the most common ones: If, Elif, and Else if, elif, and else are used for conditional execution, i.e., to execute a certain block of code if a certain condition is met. if: The if statement is used to test a specific condition. If the condition is True, the block of code under it is executed....

Python data structures

Data structures in Python are used to store collections of data in an organized and efficient way. Here are some of the most common ones: Lists A list in Python is a collection of items. Lists are ordered, changeable, and allow duplicate values. Lists are written with square brackets. # Example of list data type my_list = ["apple", "banana", "cherry"] Tuples A tuple in Python is similar to a list. The difference between the two is that tuples are immutable, which means we cannot change the elements of a tuple once it is assigned....
