By looking at the setup graphics of the four types of rotation, you can easily see that the height of the affected subtree after the insertion is the same as before. WebbAVL Tree is invented by GM Adelson - Velsky and EM Landis in 1962. The tree is named AVL in honour of its inventors. AVL Tree can be defined as height balanced binary search tree in which each node is associated with a balance factor which is calculated by subtracting the height of its right sub-tree from that of its left sub-tree. both sides of the sky jimi hendrix both sides of the space shuttle
