Write a client program that writes a struct with a privateFIFO name (call it FIFO_XXXX, where XXXX is the pid that you got from the getpid( ) function) to the server. Have the server read the privateFIFO name and write a message back to the client. Read the message and print it on the client side. Take screenshots of the output from your client and server programs. Send the output to Blackboard. What I'm checking for on this homework is that the name got created in the client and passed correctly to the server and the server can respond to the client. Turn the background of your window white and increase the font size.

You are in charge of security at a casino, and there is a thief who is trying to steal the casino's money! Look over the security diagrams to make sure that you always have a guard between the thief and the money!
There is one money location, one thief, and any number of guards on each floor of the casino.

Task in Java, Python and CPP:
Evaluate a given floor of the casino to determine if there is a guard between the money and the thief, if there is not, you will sound an alarm.

Input Format:
A string of characters that includes $ (money), T (thief), and G (guard), that represents the layout of the casino floor.
Space on the casino floor that is not occupied by either money, the thief, or a guard is represented by the character x.

Output Format:
A string that says 'ALARM' if the money is in danger or 'quiet' if the money is safe.

1. Consider the language defined as such:

L = { w$w’ : w is a string of numbers 0-9 and can be of length ≥ 0, and w’ is the reverse string of w}

Write a recursive grammar that defines all strings in the language.

2. Using the language above, write the Java code (using recursion) that will recognize if a string is part of the language or not.

1. A priority queue is a special queue that adjusts the location of items based on some priority value. When inserted, a new value is placed in the queue ahead of every other item that has a lower priority than it. This gives us a queue that removes items from the front removing highest priority first, and from items with similar priority the ones that were inserted first. For example, if we inserted the following items with the priority {A, 1}, {B,2}, {C,2}, {D,3}, {E,1} where the lower number is a lower priority, our queue will have the items from front to back: D,B,C,A,E. Using the partial code below, you are to implement the Enqueue method so that the new node is inserted into the appropriate place in the queue based on the priority. (Assume that a higher number is higher priority, for example 0 is lowest and 10 is highest)

class Node<V,P>

{

      public V value;

      public P priority;

      public Node<V,P> next;

      Node(V value, P priority)

      {

           this.value = value;

           this.priority = priority;

      }

}

class PriorityQueue<V,P>

{

      private Node<V,P> head;

      private Node<V,P> tail;

      ...

      public void Enqueue(V value, P priority)

      {

IN java

Create a New Java Project called LastNameDuplicate.

//Given an array of N elements with each element between 1 and N, write a program to determine whether there are any duplicates.

//You must prompt the user for the array elements.

//Display the contents of the array, along with the values that are duplicated and how many times they appeared in the array.

//NOTE: N should be at least 15. Input Validation: Verify that each element entered has a value between 1 and N. If an incorrect value is entered, continuously prompt for a new value. This should not halt or terminate your program.

Technical reviews can be formal, informal, or somewhere in between. How might you decide which type of review process best fits your project? What specific qualities of your project would help guide this decision?

OBJECTIVE

Upon completion of this exercise, you will have demonstrated the ability to:

OBJECTIVE: In the second assignment, you started coding the NineGaps game by creating the skeleton of the program including the loops, inputs/outputs, and some conditions without going to the details of the game. In this third assignment, we are going to complete the game by coding the details, using what we learned so far, especially working with arrays. YAY! At the end of this assignment, we can actually play with the very first game that we created by ourselves (at least for some of us!). Here You Go…! Complete the NineGaps game: Problem 1: Simulating a two-dimensional array using one-dimensional array. In COMP-1400, we only talk about one-dimensional arrays, and two-dimensional (or more) arrays will be discussed in COMP-1410. However, in NineGaps game, we need to have a table of digits as well as table of operators for the game board. In this problem we would like to simulate a two-dimensional array using a one-dimensional array. For instance, to create a n by m table (a table with n rows and m columns) of digits, we need to create a one-dimensional array with size of n*m. Therefore, row 0 and column 0 of the table (black color) will be represented by position 0 of our array. Or row 1 and column 1of the table (yellow color) will be mapped to the cell#4 in our array. Or row 3 and column 0 of the table (dark blue) is represented by cell#9 in our array. The first step to simulate the process is to find and implement the mapping rule. Assuming we want to add an integer value in a particular row and column of the table, where 0. The language is C.

1. Using a Stack, describe the algorithm below (with pre conditions and post conditions) how you would check a block of code and be sure it has the appropriate amount of curly brackets { }. (java)

Create and test a Windows Console application that displays the following patterns separately, one after the other. You MUST use nested for loops to generate the patterns, like the example in the PowerPoint slides from this chapter. All asterisks (*) should be displayed by a single statement of the form Console.Write("*"); which causes the asterisks to display side by side. A statement of the form Console.WriteLine(); can be used to move to the next line. A statement of the form Console.Write(" "); can be used to display a space for the last two patterns. There should be no other output statements in the application, other than labeling each pattern. The application's output should look like the following: Remember, use Debug, Start Without Debugging (CTRL-F5) to run your Console application. For Pattern C and Pattern D, you will need TWO loops (one after the other) nested inside your outer loop. The first loop will produce a certain number of spaces. The second loop will produce a certain number of stars. One of these numbers will be the current value of your outer loop's control variable. The other number must be calculated using ALGEBRA. Consider, how many spaces and stars are being output on each row? Always the same amount (here, 10 or MAX_ROWS, if using the same named constant as in the PowerPoint slide code given for Pattern A). So, (# spaces) + (# stars) = MAX_ROWS This equation is easy to solve for the number of spaces needed (assuming your outer loop control variable represents that number of stars per row, as in the PowerPoint slide code given for Pattern A): (# spaces) = MAX_ROWS - (# stars) or (# spaces) = MAX_ROWS - row if you name your variables as in the PowerPoint slide code given for Pattern A. So, you can make your first nested loop start at 1 and count up to (MAX_ROWS - row), outputting a single space on each iteration

Finish the calories_burned_functions.py program that we started in class. Take the original calories_burned program and rework it so that it uses two functions/function calls.

Use the following file to get your program started:
