Monica realizes there is probably a big market for a program that could help users organize a stuffed animal collection. She envisions a program that will essentially be a list of lists. Each stuffed animal will have a list of information (year made, value, condition, etc.) and those lists will be stored in a master list called masterList. Monica writes the following algorithm for the "pickToSell" procedure: The procedure will sort masterList according to the value of the stuffed animals (most valuable to least valuable). Then the procedure will ask the user for a desired value. The procedure will print out the names of the stuffed animals that have a value greater than the desired value. Rachel and Chandler will each create a version of this program. Rachel plans to use Python to implement the program and Chandler is going to use Java. Which of the following statements are true? Select TWO answers.
a) Monica's algorithm will be more helpful for Chandler than Rachel
b) Rachel and Chandler will have to use iteration, selection, and sequencing to execute this algorithm.
c) It's important that Monica's algorithm is clear and readable.
d) The algorithm that Monica wrote can be implemented on a computer as is.

Answers

Rachel and Chandler will have to use iteration, selection, and sequencing to execute this algorithm. The algorithm that Monica wrote can be implemented on a computer as is.

How to explain the information

The choice of programming language (Python or Java) does not determine the helpfulness of the algorithm. Both Python and Java provide the necessary features to implement the algorithm effectively.

. Implementing the algorithm requires the use of iteration (looping through the masterList), selection (comparing values and filtering based on the desired value), and sequencing (executing the steps in a specific order).

Assumme that you are hiired as an intern at Amazon for the summer and that you have successfully completed all hiring related forms required by the Human Resources manager. Assume an HRM software prrocesses payroll checks for interns like you, two times a month. Then this software is an example of:
A. Office Automation System
B. Online Transaction Processing System
C. Batch Transaction Processing System

Answers

C. Batch Transaction Processing System

Based on the scenario provided, the HRM software that processes payroll checks for interns twice a month is an example of a Batch Transaction Processing System (BTPS).

A BTPS is a type of computer system that processes a large volume of data at once, in batches. In this case, the software is processing payroll checks for all interns at Amazon on a set schedule twice a month.

The BTPS is designed to handle large volumes of data efficiently and accurately, and is commonly used for processing financial transactions, such as payroll checks. Unlike Online Transaction Processing Systems (OTPS), which process data in real-time, BTPS systems process data in batches at predetermined intervals.

It is worth noting that while BTPS systems are highly efficient for processing large volumes of data, they are not designed for real-time or immediate processing. Therefore, if Amazon were to require more real-time processing of payroll checks, an OTPS system may be more appropriate.

what must be true before performing a binary search? the elements must be sorted. it can only contain binary values. the elements must be some sort of number (i.e. int, double, integer) there are no necessary conditions.

Answers

Before performing a binary search, make sure the list of elements is sorted and contains numerical data, and the algorithm can be executed accurately.

To perform a binary search, the most important requirement is that the list of elements must be sorted. The algorithm works by repeatedly dividing the list in half until the target element is found or determined to be not present. If the list is not sorted, this division cannot be performed accurately, leading to incorrect results. Additionally, binary search is typically used for numerical data, so the elements must be some sort of number such as an integer or double. However, there are no other necessary conditions for performing a binary search. As long as the list is sorted and contains numerical data, the algorithm can be applied.

Answers

False. A brute-force attack is less efficient than a dictionary attack. This is because a brute-force attack involves trying every possible combination of characters until the correct password is found.

False. A brute-force attack is not more efficient than a dictionary attack. In a brute-force attack, the attacker tries all possible combinations of characters until the correct one is found.

This can be extremely time-consuming and resource-intensive, especially if the password is complex and long. On the other hand, a dictionary attack uses a pre-computed list of commonly used passwords, words from a dictionary, and variations of them to try and guess the password. This approach can be much more efficient than a brute-force attack, as it tries the most likely password combinations first before moving on to less likely ones. However, if the password is not in the dictionary, the attack will fail. In summary, both types of attacks have their strengths and weaknesses, and the most effective one will depend on the specific circumstances and the strength of the password being targeted.

Answers

False. The term "default constructor" does not refer to the first constructor written by the author of the class.

The term "default constructor" in object-oriented programming does not necessarily refer to the first constructor written by the author of the class. A default constructor is a special constructor that is automatically generated by the compiler when no explicit constructors are defined within the class. It is called "default" because it provides default values to the class's member variables. The default constructor is parameterless, meaning it does not take any arguments.

If the author of the class writes their own constructor(s), including a parameterless constructor, it would override the default constructor generated by the compiler. The author can still define their own default constructor if they want to provide specific default values or perform certain initialization tasks. In such cases, the author's constructor would be the default constructor for that class, not necessarily the first one written. Therefore, the term "default constructor" is not determined by the order in which constructors are written by the author.

The visit all vertices in a graph, Depth First Search (DFS) needs to be called multiple times when: O The graph is acyclic. O The graph is a tree. O The graph is not connected. O The graph has cycles.

Answers

DFS (Depth First Search) is a graph traversal algorithm that can be used to visit all vertices in a connected graph.

If the graph is not connected, there can be multiple disconnected components, and a separate DFS traversal is required for each component to visit all the vertices in the graph. Therefore, DFS needs to be called multiple times when the graph is not connected. However, if the graph is connected, DFS only needs to be called once to visit all the vertices, regardless of whether the graph is acyclic or has cycles.

It's important to note that DFS is typically used for searching or traversing a graph, rather than finding the shortest path between two vertices. Additionally, DFS may not work well for very large graphs or graphs with many cycles, as it can result in very deep recursion stacks.

assume that block 5 is the most recently allocated block. if we use a first fit policy, which block will be used for malloc(1)?

Answers

In memory allocation, different policies are used to find a suitable block of memory to allocate for a new request. One of the policies is the first fit policy, which searches for the first available block that can satisfy the size of the requested memory.

Assuming that block 5 is the most recently allocated block and we use the first fit policy, the policy will start searching for a suitable block from the beginning of the memory region. It will check each block until it finds the first available block that can satisfy the size of the requested memory. If the requested memory size is 1 byte, then the first fit policy will allocate the first available block that has at least 1 byte of free space. This block could be any block that has enough free space, starting from the beginning of the memory region. In conclusion, the block that will be used for malloc(1) using the first fit policy cannot be determined without more information about the sizes of the previously allocated blocks and their current free space. The policy will search for the first available block that can satisfy the requested memory size and allocate it.
