IRC is an older application layer protocol which is the ancestor of many modern message applications. While it has greatly declined in popularity, there are still several million people using IRC.

IRC is a text only chat based protocol. There are many IRC clients you can use, and several of them are web based.

Connect to an IRC room of your choice, and post a screenshot and short description of the room and how you found it.

Problem 1:

Given an array A[0 ... n-1], where each element of the array represents a vote in the election. Assume that each vote is given as integers representing the ID of the chosen candidate. Write the code determining who wins the election.

Problem 2:

How do we find the number which appeared maximum number of times in an array?

( Use Java and an original code )

I am not even sure what the question is for the problem below, but I have highlighted what I think the question is further down:

Let v = (v1, v2) and w = (w1, w2) be vectors in 2 space.

The Scalar Product of v and whose notation is v (dot) w, is defined as follows: V (dot) w : = v1*w1 + v2 *w2

The scalar product (aka inner product, or dot product) Scalar product of 2 vectors in 2-space using 4 float parameters (the function scalarProduct 1)

ACTUAL QUESTION (I think ) - Code the following in Python:

Write a docstring; then write some test function calls; then implement the body of the function

Some test data: (1., 1.) · (2,3) = 5 (or, as a function call: scalarProduct1)

(1., 1., 2., 3.) (1.,1.) · (2,0) = 2

(1., 1.) · (0,2) =2

(1., 1.,) · (4,5) =23

For each of the following, describe how to implement the operation of the variable "int x" using only bitwise, addition, and subtraction operators (<<, >>, +, -, &, |, ^, ~)

A) x * 2

B) x * 14

C) x * -44

D) x * 1023

Problem 2. Floating point encoding. Write out the 32 bit IEEE floating point binary representation for each of the following numbers:

A) 1.0

B) -2.0

C) -1000000.00

D) nan

E) -inf

F) 3.402823e38

You work for a bank that has a program with a dependency of the account class. Unfortunately the hard drive that contained the source code for the account class went bad and no backup can be found. Obviously, this means you bank needs to address this issue. However, your task is to recreate the account class. The good news is that your company was able to locate a tester of the account class and one helper function to output the class. Using these two files, you should be able to re-engineer account.h and account.cpp to work as originally designed.

Implement the account class.

main.cpp:

#include <iostream>
#include "account.h"
#include "account_output.h"
using namespace std;
using namespace DS;

int main() {

    cout << "Account Tester" << std::endl;

    //Create an account with 3.0% interest rate
    account savings(0.03);
    //Deposit one dollar
    savings.deposit(1.00);
    //Account should have exactly $1 in it
    cout << savings << endl;

    //Move up a week
    savings.advanceDay(7);
    cout << savings << endl;

    //Deposit $450.55
    savings.deposit(450.55);
    cout << savings << endl;

    //Move up 23 days, should see our first compound
    //However, the average balance not 451.55, since the balance was $1 for 7 of the 30 days
    savings.advanceDay(23);
    cout << savings << endl;

    //Advance a bunch with balance unchanged, two compoudings happen
    savings.advanceDay(65);
    cout << savings << endl;

    //Deposit more
    savings.deposit(1000);
    cout << savings << endl;

    //Advance a bunch with balance unchanged, at least two more interest calculations
    savings.advanceDay(65);
    cout << savings << endl;

    //Will not mutate object, amount must be > 0
    savings.deposit(-1000);
    cout << savings << endl;

    //Will not mutate object, amount must be > 0
    savings.withdraw(-1000);
    cout << savings << endl;

    //Will not mutate object, amount must < balance
    savings.withdraw(-10000);
    cout << savings << endl;

    //lower balance by 50
    savings.withdraw(50);
    cout << savings << endl;

    savings.advanceDay(30);
    cout << savings << endl;

    return 0;
}

account_output.h: Overload of the << operator to display the balance and week number.

#ifndef PROJECT_SAVINGS_ACCOUNT_OUTPUT_H

IN JAVA create a program that has 8 players and ranks them randomly and contains 3 rounds. For each round the highest ranked player plays the lowest ranked one i.e., in quarter-final round, player ranked 1 plays player ranked 8, player ranked 2 plays player ranked 7 and so on. Report the winner of each match, simulating using random values of your choice USING JAVA COLLECTIONS IS NOT ALLOWED

WRITTEN IN C PLEASE.

Write a switch statement that tests the value of the char variable response and performs the following actions: if response is y, the message Your request is being processed is printed if response is n, the message Thank you anyway for your consideration is printed if response is h, the message Sorry, no help is currently available is printed for any other value of response, the message Invalid entry; please try again is printed

Consider a discrete fully observable world with S states. How many distinct simple reflex agents, each with A actions, can be written for such a world? Two agents are distinct if there exists some world state where they take different actions.

Assignment #2*: Build A Report Purpose: Exercise, use, Inputs, Outputs, and perform conditional evaluation Requirements: (Multiple classes/Multiple types of input) • Input: Report Owner’s full name and 7 numbers (at least one double and one integer) o The owner’s name cannot contain any special characters, blank spaces, or numbers • You must use an if statement and at least one switch statement in your program • You are not allowed to have static variables or methods in any class except for the class with the main method. • You have to have at least 2 classes • You are not allowed to use ArrayLists or Vectors, only primitive arrays or string arrays if you want. Application Operation: 1.) Input, via a question in the console, the report owner’s first name as a string and build the last name via input, one character at a time. a. Check, conditionally, to make sure the first name and last name don’t contain any numeric characters, numbers between 0 – 9. If it does you must remove it. The names can not contain any white space either or special characters. 2.) Input report name via a request from the console. 3.) Input, and display, the total of the numeric input after each input is entered. Average the numeric input, indicate lowest numeric input value and the highest numeric input value for the previous numeric inputs, before the next numeric input is asked for. (Example given in class) 4.) Have a program exit input, condition, value available (i.e. if you type -1 the program exits) 5.) Create and display a final report that should have the report name, owner and the following: Numeric output should appear as a table with the following columns: (columns should be underlined) a. Input Number b. Highest Number c. Lowest Number d. Total (by the row) e. Average Number 6.) At the end of the report you must have a grand total for the numeric entries

Develop a C# console application that will implement one method that will return an integer value, one void method that will calculate an average, and one void overload for the calculate method that will compute a total. Please read the requirements below carefully. In Main: You will need four variables: an integer value to hold a random value, a double value to hold an average, a double value to hold a total, and a double value to hold an input entry. Using a for loop that will call a get random method 20 times. In the loop, you will pass a seed value to the get random method to use with the random generator and it will return a random value to be added to (accumulate) to the local integer variable in Main. In the getRandommethod, you will generate a random value between 1 and 100 (see p241, section 7.9) and return that random value to Main. The random value will be generated to get random using a Random class object. Once the loop has completed the 20 method calls you will call a calculate method which returns no value and to which you will pass the total of the random values, the average variable by reference, and the literal value of 20. In the calculate method you will compute an average by dividing the total of the random number passed in by the literal value 20 that was passed into the calculate method. After the calculation method executes you will display the average to the console. Following the writeline statement noted above, you will implement a second for loop that will process 5 iterations. Within this for loop you will prompt the user to enter a double value from the console and then assign that input to the double variable declared to hold the input entry. Also within the loop you will call an overload of the void calculate method and will pass two arguments: the entry taken from the console and the variable to hold the total by reference. The overload of the void calculate method will receive the double entry value and the byref double variable that will receive the total. In the overloaded calculate method you will add the value passed in to the total variable. After the overloaded calculate method executes you will display the total to the console. and I want the screenshot of the output too.

A group of 2 n 1 routers are interconnected in a centralized binary tree, with a router ateach tree node. Router i communicates with router v by sending a message to the root of the tree. The root then sends the message back down to u. Derive an expression for the average number of hops per message for a router to communicate with another router. You do not have to simplify the expression derived. Hint. Use the height of a router from the root the tree.

(a) Consider the following MIPS memory with data shown in hex, which are located in memory from address 0 through 15. Show the result of the MIPS instruction “lw $s0, 4($a0)” for machines in little-endian byte orders, where $a0 = 4.  

(b) )Assume we have the following time, performance and architecture parameters in the specified units.

Ec = execution time in cycles/program

Es = execution time in seconds/program

Pr = performance rate in instructions/seconds

CCT = clock cycle time in second/cycle

CR = clock rate in cycle/second

IC = instructions in instructions/program

CPI = average cycles per instruction in cycle/instruction

Complete the following formulas with the appropriate parameter

      CR = 1/____,                ____ = IC´ CPI,             Es =  ____ ´ CPI ´ CCT

Write a C++ program that uses a de-duplication function that iteratively sanitizes (removes) all consecutive duplicates in a C++ string. Consecutive duplicates are a pair of duplicate English alphabets sitting next to each other in the input string. Example: "AA", "KK", etc., are all consecutive duplicates. This function will internally run as many iterations as needed to remove all consecutive duplicates until there is either no consecutive duplicates left, or the string becomes empty (in which the function returns "Empty" back to the user):

string deduplicate(string input)

Your main() may look like the following, or anything you prefer to put in it as it is not graded:

int main() {
  cout << deduplicate("AABB"); // should output "Empty"
  cout << deduplicate("A"); // "A"
  cout << deduplicate("ABBA"); // should output "Empty"
  cout << deduplicate("AAA"); // "A"
  cout << deduplicate("AKA"); // "AKA" because there is no consecutive pair.
  return 0;
}

-----------------------------------------------------------

Examples:

• "KCCK" -> first iteration results in "KK" by removing "CC" as consecutive duplicates -> second iteration starts with "KK" as consecutive duplicates hence removed. Function returns "Empty".
• "ZZZ" -> first iteration results in "Z" by removing the first "ZZ". There is nothing to be removed after that. Function returns "Z".
• "KKCCD" -> first iteration removes "KK" resulting in "CCD" -> second iteration removes "CC" resulting in "D". There is nothing left to be removed. Function return "D".

-----------------------------------------------------------

Constraints/Assumptions:

• Input string consists of only uppercase English alphabets, "A" - "Z".
• Input string consists of at least 1 English alphabet.
• Input string consists of at most 100 alphabets.
• Function returns the non-reducible string.
• If the reduced string is empty, function returns the string "Empty".

Write the following questions as queries in SQL. Use only the operators discussed in class (no outer joins)

Consider the following database schema:

INGREDIENT(ingredient-id,name,price-ounce)

RECIPE(recipe-id,name,country,time)

USES(rid,iid,quantity)

where INGREDIENT lists ingredient information (id, name, and the price per ounce); RECIPE lists recipe information (id, name, country of origin, and time it takes to cook it); and USES tells us which ingredients (and how much of each) a recipe uses. The primary key of each table is underlined; rid is a foreign key to RECIPE and iid is a foreign key to INGREDIENT

Write the following queries in SQL.

1. Find the names of French recipes that use butter and take longer than 45 minutes to cook.

2. Find the names of recipes that use butter or lard.

3. Find the names of recipes that use butter and lard.
