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

## Problem
You are required to solve the `Move Tail to Head` problem in a linked list. In this exercise, you are supposed to move the tail (or last) node in a singly linked list to the front of the linked list so that it becomes the new head of the linked list.

For example, in the illustration below, the tail node (`D`) moves to the start of the linked list and replaces the head node (`A`).
