Can someone advise me how can I build an AVL tree becouse I have difficulties
with the rotations. Since if I add a node I want to be abel to check whether
the tree is balanced or not if balanced ok but if not I need to do one of
the 4 rotations which is a problem for me and I want to be able to give the
nodes from the keyboard. What I mean is that it is possible to build the
tree from scratch. Thanks to all!
