Say that we want to maintain both a Queue and a Priority Queue. This means that when you do Enqueue you also add the item to the Priority Queue and when you do Dequeue you also remove the item from the Priority Queue. And vise-versa. Show how to do it.

Write pseudo codes or explain in words and the running time.

Priority Queue Application: Use your Java's Priority Queue. Make a priority queue to represent customers being served at the Department of Motor Vehicles. Start with 100 customers in a List. In a loop, generate a priority for each customer (1-5) In a second loop, add the users to a priority queue Print the List and the Priority Queue

Implement a priority queue using a DoublyLinkedList where the node with the highest priority (key) is the right-most node. The remove (de-queue) operation returns the node with the highest priority (key). If displayForward() displays List (first-->last) : 10 30 40 55 remove() would return the node with key 55. Demonstrate by inserting keys at random, displayForward(), call remove then displayForward() again. You will then attach a modified DoublyLinkedList.java (to contain the new priorityInsert(long key) and priorityRemove() methods). Use the provided...

There are many ways to implement a priority queue, with differernt efficiencies for the two primary operations. For this lab,...

Suppose we want to test whether or not three means are equal. We want to perform this test with a 2% significance level. If we perform an ANOVA test, what is the probability of the test producing accurate results (avoiding a Type I error)? Suppose we, instead, run three separate hypothesis tests (t-tests), each with 2% significance level. Mean 1 = Mean 2 Mean 1 = Mean 3 Mean 2 = Mean 3 What is the probability that all three...
