Nthis problem you’ll add a countnegative method to an existing linked list implementation. you should create a public non-final class named yoursimplelinkedlist that extends simplelinkedlist. your class should override protected int countnegative() and return the count of the number of items in the list with values less than zero. note that this list only stores ints, not objects, so you do not need to cast item values to work with them as ints. while there are both recursive and iterative solutions to this problem, we expect you to solve it iteratively by following references from the start to the end of the list. public class simplelinkedlist

Howard is designing a chair swing ride. the swing ropes are 5 meters long, and in full swing they tilt in an angle of 29° outside chairs to be 2.75 m above the ground in full swing.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.

How can you make your column headings stand out?
