Tree searching

One of the best ways to search hierarchical data is to create a search tree. In Chapter 6, Understanding and Implementing Trees, we saw how to construct a binary search tree and increase the efficiency in searching. We have also discovered different ways to traverse a tree. Now, we will explore the two most popular ways of searching a tree structure commonly known as breadth first search (BFS) and depth first search (DFS).

Breadth first search

In a tree structure, a root is connected to its child node, and each child node can be represented as a tree. We have already seen this in Chapter 6, Understanding and Implementing Trees. In a breadth first search, popularly known as BFS, we start from a node (mostly root...

Beginning Java Data Structures and Algorithms

Beginning Java Data Structures and Algorithms

Learning about data structures and algorithms gives you a better insight on how to solve common programming problems. Most of the problems faced everyday by programmers have been solved, tried, and tested. By knowing how these solutions work, you can ensure that you choose the right tool when you face these problems. This book teaches you tools that you can use to build efficient applications. It starts with an introduction to algorithms and big O notation, later explains bubble, merge, quicksort, and other popular programming patterns. You'll also learn about data structures such as binary trees, hash tables, and graphs. The book progresses to advanced concepts, such as algorithm design paradigms and graph theory. By the end of the book, you will know how to correctly implement common algorithms and data structures within your applications.
