Suppose you have one machine and a set of n jobs a1,a2,...an to process on that machine. Each job a, has a processing time tj, a profit p, and a deadline d,. The machine can process only one job at a time, and job a, must run uninterrupted for t, consecutive time units. If job aj is completed by its deadline d,, you receive profit p,, but if it is completed after its deadline, you receive a profit of 0. Give an algorithm to find the schedule that obtains the maximum amount of profit, assuming that all processing times are integers between 1 and n. What is the running time of your algorithm?
Answers
The running time of this algorithm is O(n log n).
The problem described can be modeled as a scheduling problem, where the objective is to maximize the total profit earned by completing jobs within their respective deadlines.
To find the schedule that obtains the maximum profit, we can use the following algorithm:
1. Sort the jobs in decreasing order of their profits.
2. For each job, starting from the one with the highest profit, assign it to the earliest available time slot that is after its release time and before its deadline.
3. If there is no available time slot for a job, skip it. The running time of this algorithm is O(n log n), dominated by the time taken to sort the jobs. This can be improved to O(n) using bucket sort or radix sort if the processing times are bounded by a constant.

Write a program that determine the admission price for a person to attend the sectionals game. Any day prior to game day, adult tickets cost $10, and student tickets cost $6. On game day, the cost of each ticket goes up by $1. People with a coupon can get a discount. Anyone with coupon code CHS2021 gets a 5% discount, and anyone with coupon code CHSVIP gets a 10% discount. This program should have 3 functions:
askUser: This function asks the user all of the important questions (adult or student, game day or not, if they have a coupon or not and if so what the code is). This function takes in NO parameters and returns NO values. This function updates 4 global variables: status ("a" or "s" for adult or student), gameDay (True or False), hasCoupon (True or False), and coupCode ("CHS2021" or "CHSVIP").
getCost: This function takes in two parameters: string st (for status "a" or "s") and boolean gd (for game day True or False). Based on the inputted values, it calculates and returns one integer value, cost.
getDiscount: The function takes in two parameters: coup (coupon code, "CHS2021" or "CHSVIP" ) and c (cost). The function should only be called if hasCoupon is True. The function calculates and returns one decimal (float) value for the new discounted cost, discCost.
Example output:
Are you a student or adult (enter s or a)? a
Is this for a game today? no
Do you have a coupon? yes
What is the code? CHS2021
Your cost is: $9.5

Explanation:
A public subclass for ICalculator1 has one additional method, sign, that receives no arguments, and doesn't modify current Value. Instead, it simply returns 1, 0 or -1 depending on whether current Value is positive, zero, or negative respectively.
What is public subclass?A member's access is declared to be public with the Java keyword public. All other classes can see members of the public class. This implies that a public field or method can be accessed by any other class. In addition, public fields can be changed by other public subclass or classes unless they are marked as final.
Further a subclass is defined as a class that is descended from another class (also a derived class, extended class, or child class). A superclass is the class from which a subclass is descended (also a base class or a parent class).
A public subclass for ICalculator1 has one additional method, sign, that receives no arguments, and doesn't modify current Value:
In Java,

public int sign() {
if (getCurrentValue() > 0)
return 1;
else if (getCurrentValue() == 0)
return 0;

.In real-world social networks, BFS is often favoured over DFS because it simulates information flow, makes it possible to perform operations like shortest path finding and network connectivity analysis, and ensures systematic investigation of connections for a thorough understanding of the network.
The Breadth-First Search (BFS) algorithm is typically preferred over Depth-First Search (DFS) in a real-world social network. BFS mimics the way information flows in a network by accessing nodes at each level before advancing to the next level as it explores the social network. Because of this, BFS is appropriate for tasks like determining the shortest path, examining network connections, or locating communities. DFS, on the other hand, is less effective for massive social networks since it can get stuck in deep branches.

The code snippet you provided seems to be a method declaration in Java. Let me break it down for you:
1. The method is named "gettopitemizedspends" and it has a return type of "list". In Java, the return type "list" refers to an interface that represents an ordered collection of elements.
2. The method is defined as being public, which means it can be accessed from other parts of the code.
3. The method does not seem to take any parameters. If it did, you would see them inside the parentheses.
4. The method body is not provided in the code snippet you shared. It is indicated by the curly braces {}. The implementation of the method should be written inside these braces according to the requirements stated in the javadoc and readme.
5. The comment "// participants: implement according to javadoc and readme list report" suggests that there are specific instructions in the javadoc and readme files that should be followed when implementing the method. The purpose and functionality of the method should be documented in these files.
Without the complete code and relevant documentation, it is difficult to provide a more detailed explanation. However, based on the information given, it appears that the method is expected to return a list of top itemized spends, possibly as part of a financial reporting system.

which type of enabler does a system architect review during a system demo?
Answers
During a system demo, a system architect usually reviews 'Architectural Enablers'.
These are architectural assets that facilitate the functioning, performance, and evolution of the system, and they directly influence its development and delivery. Architectural Enablers can include system software, hardware components, or standards that aid the system's functionality and performance. They are usually captured in the form of user stories, features, or capabilities. During a system demo, the system architect reviews these enablers to evaluate their effectiveness in supporting the system's design and functionality. This review can lead to valuable insights into the system's structure, interoperability, scalability, performance, and maintainability. It also helps identify potential risks and areas of improvement, ensuring the system's architecture meets its intended design, user needs, and business goals.

During a system demo, a system architect typically reviews various types of enablers that contribute to the overall functionality, performance, and reliability of the system. Enablers are the supporting elements that facilitate the successful operation of the system and include hardware, software, infrastructure, and other components.
One type of enabler that a system architect reviews is the hardware infrastructure. This includes servers, networking equipment, storage devices, and any other physical components necessary for the system's operation. The system architect assesses whether the hardware meets the system's performance, scalability, and availability requirements. They examine factors such as processing power, memory, storage capacity, and network bandwidth to ensure that the system can handle the expected workload and data volume.
Another important enabler that a system architect reviews is the software architecture. They examine the system's software components, such as the application code, libraries, frameworks, and APIs. The architect verifies that the software architecture follows best practices and design principles, including modularity, reusability, and maintainability. They also check if the software components interact effectively and efficiently, ensuring proper communication and data flow between modules.
Additionally, a system architect reviews the infrastructure enablers, which include the operating system, middleware, databases, and other supporting software. They evaluate whether the infrastructure components are compatible with the system's requirements and if they provide the necessary services and functionalities. The architect also ensures that the infrastructure is properly configured, optimized, and secured to support the system's performance, reliability, and security goals.
Furthermore, during the system demo, the system architect may review non-functional enablers such as performance metrics, system monitoring and logging capabilities, security measures, and disaster recovery mechanisms. They assess whether the system meets the defined non-functional requirements, such as response time, throughput, security controls, and fault tolerance.
