Explanation of Solution
Priority Queue:
A PriorityQueue is a class which is used at that time of objects are processed depends on priority. It follows the queue format such as First-In-First-Out
Syntax to create object for PriorityQueue class:
PriorityQueue<dataType> objectName = new PriorityQueue<dataType>();
Create an integer PriorityQueue:
The integer PriorityQueue is created by using the constructors of PriorityQueue.
The following code is creation of integer PriorityQueue.
PriorityQueue<Integer> pq = new PriorityQueue<Integer>();
Therefore, the PriorityQueue is created by using the constructor of PriorityQueue...

- what is the suggestion for improving the Binary search tree? (write the reference that helps you to answer)arrow_forwardDevelop a procedure that will allow you to remove from a linked list all of the nodes that share a key?arrow_forwardHi! Currently stuck in a java problem and would appreciate the help! Question: You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)! The teque supports the following four operations: push_back x: insert the element ?x into the back of the teque. push_front x: insert the element ?x into the front of the teque. push_middle x: insert the element ?x into the middle of the teque. The inserted element ?x now becomes the new middle element of the teque. If ?k is the size of the teque before the insertion, the insertion index for ?x is (?+1)/2(k+1)/2 (using 00-based indexing). get i: prints out the ?thith index element (00-based) of the teque.…arrow_forward

- Can you elaborate on the distinction between the bound and unbounded stacks?arrow_forwardI'm trying to delete a node after inputting data for 2-3 checks but the node I try to delete remains in the list.
