Lesson 26.5 While-Loops vs For-Loops

We can always replace for-loops with while-loops, but should we? In this video we talk about the trade-offs of the two control structures and why it might be better to use over the other.

Zoom Oct. 22. More Recursion

The divide-and-conquer examples we saw in the previous session were on the easy side. In this session we look at some much more challenging examples.Included in this session is segregate, the most…

Lesson 17.10 Recursion and Helper Functions

Divide-and-conquer is not the only example of recursion. It just happens to be one of the most interesting. But in this video we show that even some of the simplest of recursive definitions become…

Lesson 17.8 Recursion Performance

In this video, we show another reason to pay attention to the division step: performance. In fact, we show an example where a change in how we divide the data can improve performance by several…

Lesson 17.6 Divide and Conquer Visualization

Just because you know how to write a divide-and-conquer algorithm does not mean you understand it. In this video we try to improve our understanding by visualizing divide-and-conquer. When we do this…

Lesson 17.5 Divide and Conquer Design

Now that we understand divide-and-conquer, it is type to implement it in Python. In this video we show you a three-step sequence for writing a function definition using this technique.

Lesson 17.4 Divide and Conquer

Recursion has many, many uses. But one of the most popular applications is divide-and-conquer. In this video we introduce this new concept and show how we will use to solve several problems on…

Lesson 17.3 Recursion and the Call Stack

Because a recursive function calls itself, it will have multiple call frames on the call stack. In this video we show exactly why we should be concerned about this and why it will affect our function…

Lesson 17.2 Recursive Functions

In this video we show how to take recursive definitions from mathematics and implement them in Python. To do this, we will need to have a function call itself in its own definition.

Lesson 17.1 Recursive Definitions

Recursion is a general concept that does not just apply to programming languages. In this video we show that recursion exists in mathematics and even natural language.
