==Overview==

A binary search tree is a rooted binary tree in which the nodes are arranged in [[total order#Strict and non-strict total orders|strict total order]] in which the nodes with keys greater than any particular node ''A'' is stored on the right [[Tree (data structure)#Terminology|sub-trees]] to that node ''A'' and the onesnodes with keys equal to or less than ''A'' are stored on the left sub-treetrees to ''A,'' satisfying the [[binary search]] property.<ref name="reema18">{{cite book|title= Data Structures Using C|date=13 October 2018|edition=2|first=Reema|last=Thareja|publisher=[[Oxford University Press]]|url=https://global.oup.com/academic/product/data-structures-using-c-9780198099307|isbn= 9780198099307|url-access=subscription|chapter=Hashing and Collision}}</ref>{{rp|p=298}}<ref name="algo_cormen">{{cite book|last1=Cormen|first1=Thomas H. |author-link1=Thomas H.

Binary search trees are also efficacious in [[sorting algorithm|sorting]]s and [[search algorithm]]s. However, the search complexity of a BST depends upon the order in which the nodes are inserted and deleted; since in worst case, successive operations in the binary search tree may lead to degeneracy and form a [[singly linked list]] (or "unbalanced tree") like structure, thus has the same worst-case complexity as a [[linked list]].<ref>{{cite journal|journal=[[The Computer Journal]]|volume=25|issue=1|date=1 February 1982|doi=10.1093/comjnl/25.1.158|author1=R.
