A BST is a binary tree that is built in such way that the tree is always sorted. This means the left child node has a value less than or equal to the parent node value, and right child node will have the value greater than the parent node value. So, whenever we need to search a value, either we will search left or search right. As it is sorted, we have to search one part of the tree, not both, and this continues recursively. For its dividing nature, the searching becomes very fast, and we can achieve logarithmic complexity for the search. For example, if we have n number of nodes, we will search either the first half or second half of the nodes. Once we are in the first or second half, we can divide it again into two halves, which means our half now becomes a quarter, and it goes on and on until we reach the final node. As we are not moving...

Overview of this book
PHP has always been the the go-to language for web based application development, but there are materials and resources you can refer to to see how it works. Data structures and algorithms help you to code and execute them effectively, cutting down on processing time significantly.
If you want to explore data structures and algorithms in a practical way with real-life projects, then this book is for you.
The book begins by introducing you to data structures and algorithms and how to solve a problem from beginning to end using them. Once you are well aware of the basics, it covers the core aspects like arrays, listed lists, stacks and queues. It will take you through several methods of finding efficient algorithms and show you which ones you should implement in each scenario. In addition to this, you will explore the possibilities of functional data structures using PHP and go through advanced algorithms and graphs as well as dynamic programming.
By the end, you will be confident enough to tackle both basic and advanced data structures, understand how they work, and know when to use them in your day-to-day work
