Discover data structures and algorithms using Python. Gain insights into solving real-world problems and typical interview questions with detailed reviews, explanations, and hands-on coding exercises.

Data structures and algorithms are among the most fundamental concepts of Computer Science. Whether it’s real-world problems you’re trying to solve or the typical coding question asked in an interview, almost every problem requires you to demonstrate a deep understanding of data structures and algorithms. 

This course is a detailed review of some of the most common data structures and algorithms that you’ll see in interviews and your everyday work. With implementation details, thorough explanations, and hands-on coding exercises, you’ll quickly gain the confidence you need to solve any problem, no matter the situation.

Data Structures and Algorithms in Python

In this lesson, we consider how to reverse the nodes in a doubly linked list. Once we cover the concept of how to perform this action, we follow through with a Python implementation.

## Algorithm
To reverse a doubly linked list, we need to switch the next and the previous pointers of every node. Also, we need to switch the last node with the head node of the linked list. Check out the illustration below for more clarity:
