Data Structures and Algorithms The Complete Masterclass - What is Recursion?

The video tutorial introduces the concept of recursion, emphasizing its definition as a function that calls itself. It highlights the importance of a base case to prevent infinite loops. An example using a 'Hello World' function demonstrates recursion, showing how it can lead to infinite loops without a base case. The tutorial explains Python's default recursion limit and how to implement a base case to control recursion. The video concludes with a recap of key points, stressing the necessity of defining a base case in recursive functions.
