Need quick Linux help

I have to answer a question on one of my labs. We have to make a "tree" in the terminal without using the "tree" command. We have to use the ls command. I tried google and couldn't find anything other than "just use tree yo"

I've tried

ls -R
ls *

both of them come up with a tree, but it doesn't have the graphic tree design that the tree command has.

halp plz

Can you explain what you mean by "make a tree"?

Use a recursive bash script.
