Comment on Why does the for loop repeat in this recursion?

Thanks. I did see that. I have a general understanding of how recursion works I think where the function calls itself again and again but I don’t get why the code (for loop) below the draw(n - 1) is recursive.

The code below the
draw(n - 1)isn’t recursive… the call todraw(n - 1)is the recursion.Sometimes, it can be helpful to invert recursion. Think about what draw(0) would be and write it down… then compute draw(1) using the value you previously computed for draw(0).
