8. Priority Queues

The chapter discusses priority queues and their implementation, highlighting their importance in algorithms like Dijkstra's and Prim's. It explores different data structures for maintaining a list of jobs with priorities, comparing linear and two-dimensional structures. A significant focus is given to the efficiency of insert and delete operations, leading to the introduction of more advanced structures like heaps.
