When should I use trees instead of graphs?

When should I use trees instead of graphs?

You should use trees when you need a hierarchical structure, like a family tree or file system. Graphs are better for complex relationships.

Can you give me an example of a tree structure?

Sure! A common example is a directory structure on a computer, where folders can contain subfolders.

What about graphs? When are they more useful?

Graphs are useful for representing networks, like social connections or transportation routes, where relationships are not strictly hierarchical.

Are there any situations where I might use both?

Yes, in scenarios like organizational charts, you might use trees for hierarchy and graphs for showing relationships between departments.
