What is Splay Tree?
A splay tree is a self-adjusting binary search tree in which every operation on the tree is accompanied by a rearrangement of the tree to bring the accessed node closer to the root of the tree. This rearrangement is known as a "splay," and it is intended to improve the efficiency of subsequent searches by making it more likely that the node will be accessed again in the future.
Splay trees have a number of desirable properties, including the ability to perform all the operations of a standard binary search tree (such as insertion, deletion, and search) in logarithmic time. They are also self-adjusting, meaning that they do not require the use of external balancing mechanisms to maintain their shape.
One of the key features of splay trees is their ability to adapt to the access patterns of the data they store. As nodes are accessed, they are moved closer to the root of the tree, which makes it more likely that they will be accessed again in the future. This can help to improve the overall performance of the tree, especially for data sets that exhibit strong access patterns.
Splay trees are a type of data structure that is used to store and manage data in a way that is efficient and easy to search. They are widely used in a variety of applications, including database indexing, file systems, and data compression.
