Heap-Tree -- Heapsort

Heap-Tree -- Heapsort. S.Sioutas CEID@Upatras. Why study Heapsort?. It is a well-known, traditional sorting algorithm you will be expected to know Heapsort is always O(n log n) Quicksort is usually O(n log n) but in the worst case slows to O(n 2 )

AVL Tree

AVL Tree. Recursive definition of AVL Tree. An AVL tree is a binary search tree in which the heights of the left and right subtrees of the root differ by at most 1 and in which the left and right subtrees are again AVL trees. History of AVL Trees.
