Fritz is a big fan of the racerville rockets. unfortunate;y, the team has been accused of cheating during their games. Fritz reads many articles and posts about this developing news story. His social media algorithms have "learned" that he's a fan of the team, so his feed doesnt show him any articles that argue the accusations are true. From this, Fritz decides his favorite team must be innocent of all cheating charges. Fritz is now in
A. a filter bubble
B. A third party
C. A subculture
D. an echo chamber
Answers
Option(D) is the correct answer. Fritz is now in an echo chamber.
Fritz's situation aligns with the concept of an echo chamber. An echo chamber refers to an environment, such as social media, where individuals are exposed to information and opinions that reinforce their existing beliefs and perspectives.
In this case, Fritz's social media algorithms have filtered out articles that present arguments in favor of the cheating accusations, creating an echo chamber that only confirms his preconceived notion of the team's innocence.
As a result, Fritz is insulated from diverse viewpoints and alternative perspectives, which can hinder critical thinking and a comprehensive understanding of the situation.

Gains for young people include the ability to travel to different places easily, freedom and independence, and the ability to participate in social and recreational activities. Pains for young people include the high cost of transportation, lack of reliable and efficient options, and the environmental impact of certain modes of transportation.
To reimagine public transportation to suit young people's mobility needs, the following could be considered:
- Mobility services: Additional options such as bike-sharing, car-sharing, and on-demand ride-hailing services could be integrated into the public transportation landscape to provide more convenient and flexible options for young people.- Non-mobility services: Integration of technology such as mobile apps for trip planning and payment, Wi-Fi on public transportation, and the ability to order food and other goods while in transit could enhance the overall experience for young people.Infrastructure utilization: Public transportation could use its current infrastructure in innovative ways, such as converting unused spaces into retail or co-working spaces, or using buses and trams for pop-up events and experiences.
To change the image of public transportation and make it more appealing to young people, it could adopt a more modern and innovative branding strategy, including the use of social media and influencer marketing, and offering unique experiences and events on public transportation.
I believe these ideas are the best solutions for public transportation players to meet young people's mobility needs and wants because they address the key concerns and desires of young people, including convenience, affordability, accessibility, and sustainability.

To store non-duplicated objects in the order in which they are inserted, use:______
a. HashSet
b. LinkedHashSet
c. TreeSet
d. ArrayList
e. LinkedList
Answers
Answer:
b. LinkedHashSet
Explanation:
A LinkedHashSet is an ordered version of HashSet that maintains a doubly-linked List across all elements. When the iteration order is needed to be maintained this class is used. LinkedHashSet maintains a linked list of the entries in the set, in the order in which they were inserted.
A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.
Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.
Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.
Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.
The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.
The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.
Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.

What is chemical energy?Chemical energy is defined as a chemical substances' potential energy, which is released as they experience chemical reactions and change into other substances.
As the petrol engine takes 1000J of chemical energy and produces 250J of useful energy.
So, Input = 1000 J
Output = 250 J
Efficiency = (250 / 1000) 100
= 0.25 x 100

A backup operator wants to perform a backup to enhance the RTO and RPO in a highly time- and storage-efficient way that has no impact on production systems. Which of the following backup types should the operator use?
A. Tape
B. Full
C. Image
D. Snapshot
Answers
In this scenario, the backup operator should consider using the option D-"Snapshot" backup type.
A snapshot backup captures the state and data of a system or storage device at a specific point in time, without interrupting or impacting the production systems.
Snapshots are highly time- and storage-efficient because they only store the changes made since the last snapshot, rather than creating a complete copy of all data.
This significantly reduces the amount of storage space required and minimizes the backup window.
Moreover, snapshots provide an enhanced Recovery Time Objective (RTO) and Recovery Point Objective (RPO) as they can be quickly restored to the exact point in time when the snapshot was taken.
This allows for efficient recovery in case of data loss or system failure, ensuring minimal downtime and data loss.
Therefore, to achieve a highly time- and storage-efficient backup solution with no impact on production systems, the backup operator should utilize the "Snapshot" backup type.
