Recursive thinking

When managing a complex hierarchy of videos, such as sorting them into categories and subcategories, thinking recursively can simplify the process. Recursive thinking means breaking down a big problem into smaller versions of the same problem until it becomes easy to solve.

Let’s take organizing a tree of video categories and subcategories as our example. The goal is to go through each category, visit all its subcategories, and organize the videos in each. This task sounds complex, but recursion makes it easier by handling one category (and its subcategories) at a time.

Here’s how you might write a recursive function to do this:

class Category
{
    public List<Category> Subcategories;
    public List<Video> Videos;
    // Other properties like name, etc.
}
void OrganizeVideos(Category category)
{
    // First, go through each subcategory
