# Linked list and binary search tree

This process continues, until the new node is compared with a leaf node, and then it is added as this node's right or left child, depending on its key: If its key is less than the root's, it is then compared with the key of the root's left child. In the context of binary search trees a total preorder is realized most flexibly by means of a three-way comparison subroutine.

Similarly, if the key is greater than that of the root, we search the right subtree. The BST property—every node on the right subtree has to be larger than the current node and every node on the left subtree has to be smaller than the current node—is the key to figuring out whether a tree is a BST or not. In practice, the added overhead in time and space for a tree-based sort particularly linked list and binary search tree node allocation make it inferior to other linked list and binary search tree optimal sorts such as heapsort for static list sorting. There are other ways of inserting nodes into a binary tree, but this is the only way of inserting nodes at the leaves and at the same time preserving the BST structure. Binary search trees keep their keys in sorted order, so that lookup and other operations can use the principle of binary search:

Part of the material that will be taught is not covered by Greek books or it is presented in a different order. Several variants of the binary search tree have been studied in computer science; this article deals primarily with the basic type, making references to more advanced types when appropriate. The tree additionally satisfies the binary search property, which states that the key in each node must be greater than or equal to any key stored in the left sub-tree, linked list and binary search tree less than or equal to any key stored in the right sub-tree.

This is much better than the linear time required to find items by key in an unsorted array, but slower than the corresponding operations on hash tables. This problem has a simple recursive solution. Delete-min max can simply look up the minimum maximumthen delete it. If the order relation is only a linked list and binary search tree preorder a reasonable extension of the functionality is the following: In either case, this node will have only one or no child at all.

Because in the worst case this algorithm must search from the root of the tree to the leaf farthest from the root, the search operation takes time proportional to the tree's height see tree terminology. What this means is that in a performance measurement, the tree will essentially behave like a linked list data structure.

Such a tree might be compared with Huffman treeswhich similarly seek to place frequently used items near the root in order to produce a dense information encoding; however, Huffman trees store data elements only in leaves, and these elements linked list and binary search tree not be ordered. Robert SedgewickKevin Wayne: Otherwise, if the key equals that of the root, the search is successful and we return the node.

The BST property—every node on the right linked list and binary search tree has to be larger than the current node and every node on the left subtree has to be smaller than the current node—is the key to figuring out whether a tree is a BST or not. If your add node function does not handle re-balancing, then you can easily construct a degenerate tree by feeding it with data that is already sorted. Traversal can also be implemented iteratively.
