Summary

We have seen many advanced algorithms and techniques that can be used to solve different types of problems in this chapter. There are many good resources available to study these topics. Dynamic programming is such an important topic and can be covered in several chapters or have a separate book for itself. We tried to explain few of the topics, but there are more to explore. You also learned about sparse matrix and bloom filter, which can be used for efficient data storage for big data blocks. We can use these data structure concepts whenever we need them. Now, as we are reaching the end of the book, we will wrap up our discussion with some available libraries, functions, and references for data structure and algorithm in PHP 7.
