- Just need some assistance with number 3 please, in C#arrow_forwardHow do we find the possible final values of variable x in the following program. Int x=0; sem s1=1, s2 =0; CO P(s2); P(s1); x=x*2; V(s1); // P(s1); x=x*x; V(s1); // P(s1); x=x+3; V(s2); V(s1); Ocarrow_forwardLab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…arrow_forward
- If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a) Give an example of when an application might want to receive such ICMP messages. (b) Find out what an application has to do, on the operating system of your choice, to receive such messages. (c) Why might it not be a good idea to send such messages directly back to the originating port P on A?arrow_forwardDiscuss how business intelligence and data visualization work together to help decision-makers and data users. Provide 2 specific use cases.arrow_forwardThis week we will be building a regression model conceptually for our discussion assignment. Consider your current workplace (or previous/future workplace if not currently working) and answer the following set of questions. Expand where needed to help others understand your thinking: What is the most important factor (variable) that needs to be predicted accurately at work? Why? Justify its selection as your dependent variable.arrow_forward
- According to best practices, you should always make a copy of a config file and add a date to filename before editing? Explain why this should be done and what could be the pitfalls of not doing it.arrow_forwardIn completing this report, you may be required to rely heavily on principles relevant, for example, the Work System, Managerial and Functional Levels, Information and International Systems, and Security. apply Problem Solving Techniques (Think Outside The Box) when completing. should reflect relevance, clarity, and organisation based on research. Your research must be demonstrated by Details from the scenario to support your analysis, Theories from your readings, Three or more scholarly references are required from books, UWIlinc, etc, in-text or narrated citations of at least four (4) references. “Implementation of an Integrated Inventory Management System at Green Fields Manufacturing” Green Fields Manufacturing is a mid-sized company specialising in eco-friendly home and garden products.

Create a Book record that implements the Comparable interface, comparing the Book objects by year - title: String > - author: String - year: int Book + compareTo(other Book: Book): int + toString(): String Submit your source code on Canvas (Copy your code to text box or upload.java file) > Comparable 2. Create a main method in Book record. 1) In the main method, create an array of 2 objects of Book with your choice of title, author, and year. 2) Sort the array by year 3) Print the object. Override the toString in Book to match the example output: @Javadoc Declaration Console X Properties Book [Java Application] /Users/kuan/.p2/pool/plugins/org.eclipse.justj.openjdk.hotspo [Book: year=1901, Book: year=2010]arrow_forward

Consider the following pseudocode for partition: function partition (A,L,R) pivotkey = A [R] t = L for i L to R-1 inclusive: if A[i] A[i] t = t + 1 end if end for A [t] A[R] return t end function Suppose we call partition (A,0,5) on A=[10,1,9,2,8,5].

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forward
