The computer we use every day can run multiple applications at the same time, without feeling stuck, the computer assigns a priority to events for each application, and mobile phones are usually the highest priority, whether we're watching a movie or texting as long as we have a phone call. At this point we need a reasonable data structure to delete the largest element and the insertion element, which we ca

Label: style Io color OS AR for SP strong I. Simple implementation of priority queue: 1. Use a simple linked list to insert an O (1) in the header, and traverse the list to delete the smallest element. This requires O (n) time. 2. Keep the table in order. This results in a high insertion cost (O (n), while a low deletion cost (O (1 )). The fact that the operation based on the smallest element is nev

Data structure and algorithm analysis Priority Queue Model Insert (insert) = = Enqueue (queue) Deletemin (delete the smallest) = = Dequeue (out of the team) Basic implementation Simple linked list: Insert in the table header and traverse the list to remove the minimum element Time is costly.
