Summary


In this chapter, we discussed priority queues and their implementation. Priority queues are important data structures that are used in a lot of problems. We saw two implementations of a priority queue, a heap, and a binomial forest. We also saw how to use priority queues for sorting, which is asymptotically optimal. A variation of this allowed us to sort an array in place using an array-based heap.

In the next chapter, we will discuss the concept of graphs, which are very useful, almost ubiquitous ADTs, and data structures that are used in many real-life applications.
