Recursion: Understanding a Call Stack – Part 3

The video tutorial explains the concept of a call stack and how recursion works in programming. It provides a detailed walkthrough of how functions take up space in the stack memory, using examples to illustrate the process. The tutorial also covers the concept of activation records and how memory is managed during function calls. An example with print statements is used to demonstrate the execution flow, and the tutorial concludes with an introduction to tree recursion, setting the stage for more complex recursive functions in the next lecture.

In the example provided, what is the output when the function is called with a value of 3?

How can you visualize the call stack during the execution of recursive functions?

Discuss the significance of the base case in a recursive function.

What are the potential issues that can arise from excessive recursion?
