Task : Priority level "Update user profiles"
Task : Priority level "Critical system bug fix"
Task : Priority level "Database optimization"
Task : Priority level UI redesign"
Task : Priority level "Emergency server restart"
What data structure would be suitable for managing this task queue, and how can it be used to efficiently find and process the task with the highest priority?
Assuming that the data structure is correctly implemented, the task with the highest priority should be processed first.
Do Not Use java.util. package

Bookstore
Imagine you are working as a software developer for a bookstore. Your task is to create and manage a stack data structure to keep track of books in the store's inventory. Each book has the following information: title, author, publication year, and ISBN International Standard Book Number You need to implement the stack operations to maintain and update this inventory.

A customer purchases To Kill a Mockingbird" Book Remove this book from the inventory. What does the stack look like now?
Anewbookarrives:Title:"TheCatcherintheRye",Author:"JDSalinger",Year: ISBN: Add it to the inventory. What does the stack look like now?
Another customer purchases "The Great Gatsby" Book Remove this book from the inventory. What does the stack look like now?
Question: Provide the updated stack after each operation, and critically analyze how the stack data structure behaves in this inventory management scenario. How would you implement the push and pop operations to ensure books are added and removed correctly?
Please describe the stack's state and the steps involved in each operation as you answer the question.
