There are lots of tutorials out there with great graphics, code explaining the details, blah blah, so I'm not sure how much my comment can help. It is just a bit of intuition explanation. Take an array of items as the leaves of the tree, and build a tree so that at each higher l...

AVL treeto balance tree. Magiccally, the addtional functions arevery independentwith our old code. Here is some functions we need to add, it is not different from AVL tree: intlink(intll,intu,intrr){Left[u]=ll,Right[u]=rr;returnupdate(u),u;}intright_rotate(intu){intll=Left[u]...
