Hi all, im having a problem getting my head around "drawing" a Binary Search Tree and AVL Tree.

Im studying computer science, and have an exam in 4 days so need help quite quick lol.

Im looking over past exam papers and having trouble with this question:

Start with an initially empty tree, insert the values:

{81,62,93,34,75,30,56,47,18,59,50} (in that order into:1. a binary search tree, giving the final diagram;

2. an AVL tree, giving diagrams before and after each rotation

:s i just can't get my head around it. I had a shot but not sure how i can show my diagram (which iv written on paper) here on this thread as a whole diagram/image.

Kind Regards
