Time Complexity

Time and Space Complexity of B+ Tree

B+ trees an interesting name isn't it? So in this article, we will closely analyze the time & space complexities for different operations in different cases of B+ Tree Data Structure.

Data Structures

(a,b) Tree Data Structure

An (a,b)-tree is a type of self-balancing tree data structure that is designed to maintain a balance between the height of the tree and the number of elements stored in the tree. In short we can say that (a,b)-tree is a generalization of a B-tree. Now lets get to know it in depth.
