Road trip. you are going on a long trip. you start on the road at mile post a0. along the way there are n hotels, at mile posts , where a0 < a1 < a2 < ··· < an. the only places you are allowed to stop are at these hotels, but you can choose which of the hotels you stop at. you must stop at the final hotel (at mile post an), which is your destination. you’d ideally like to travel 200 miles a day, but this may not be possible (depending on the spacing of the hotels). if you travel x miles during a day, the penalty for that day is (200 − x)2. you want to plan your trip so as to minimize the total penalty—that is, the sum, over all travel days, of the daily penalties. give an efficient algorithm that determines the optimal sequence of hotels at which to stop.

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.
