Graphs are nothing but trees with certain restrictions removed. Each of these mentioned data structures has a different special way of organizing data so we choose the data structure. We can make the tree balanced, or optimal, by making the node with value 2 the new root node. Search tree data structures provide many dynamic-set operations such as search, insert, delete, minimum element, maximum element and others. These notes are used for two courses at the University of Ottawa (CSI-2114 and CSI-2301) and the course T26 at the Institute for Government Informatics Professionals. The emphasis is on the trade-offs associated with implementing alternative data structures for these ADTs. Lecture 20: Digitized Ordered Collections, Spatial Collections/k-d Tree.
