Business Case

Your company needs to conduct an analysis of a large dataset that is 10 times bigger than the size of a hard drive of your most powerful computer. This dataset contains data about ATM transactions. The security team has provided a smaller dataset of suspicious transactions. Your task is to identify transactions similar to suspicious ones.

Directions

explain which parallel computing techniques would be appropriate for this case and why. Explain which component of Hadoop ecosystem may be used in this case, and why.

Example of parallel computing could be (distributed calculations vs. MapReduce) or others

key principles of Apache Hadoop environment (Hive, Spark, Pig, etc.) or others

C++

The program you write for this lab will read in the number of nodes and a binary relation representing a graph. The program will create an adjacency matrix from the binary relation. The program will then print the following :

1. The adjacency matrix
2. Determine if there are any isolated nodes and print them
3. Determine if an Euler path exists and said so.

The sample run of the program is as follows. The output should just like this: It starts by asking the user to input the number of nodes, then ask the user to input the adjacency relation and then print out the adjacency matrix first, followed by the node that is isolated and then tells the user if an Euler path exist or not.

This is how the program should run and output

Please input the number of nodes:
6
Please input the adjacency relation:
{(1,2),(1,5),(2,1),(2,3),(3,2),(3,4),(4,3),(4,5),(5,1),(5,4)}

The Adjacency matrix is:
0 1 0 0 1 0
1 0 1 0 0 0
0 1 0 1 0 0
0 0 1 0 1 0
1 0 0 1 0 0
0 0 0 0 0 0

6 is an isolated node
An Euler path does exist in the graph.

Program 1: Stay on the Screen!  Animation in video games is just like animation in movies – it’s drawn image by image (called “frames”).  Before the game can draw a frame, it needs to update the position of the objects based on their velocities (among other things).  To do that is relatively simple: add the velocity to the position of the object each frame.

For this program, imagine we want to track an object and detect if it goes off the left or right side of the screen (that is, it’s X position is less than 0 and greater than the width of the screen, say, 100).  Write a program that asks the user for the starting X and Y position of the object as well as the starting X and Y velocity, then prints out its position each frame until the object moves off of the screen.  Design (pseudocode) and implement (source code) for this program.

In a certain building at a top secret research lab , some yttrium-90 has leaked into the computer analysts' coffee room. The leak would currently expose personnel to 150 millirems of radiation a day. The half-life of the substance is about three days; that is, the radiation level is only half of what it was three days ago. The analysts want to know how long it will be before the radiation is down to a safe level of 0.466 millirem a day. They would like a chart that displays the radiation level for every three days with the message Unsafe or Safe after every line. The chart should stop just before the radiation level is one-tenth of the safe level, because the more cautious analysts will require a safety factor of 10. The program should also print the first day that the room can be entered.

I'm having trouble understanding this concept. I already completed the first part now I need to convert the Second Part into a Control Structure. Please help answering the Problem. The first part will be below.

(Second Part)

Continuing with Control Structures

Control Structures are called such because they control the execution flow during the running of a program. There are 3 basic control structures: Sequence, Selection and Loop. This week let's work with the structures we already know - Sequence and Selection - but now let's add the loop structure to our logical programming toolbox.

Remember (from CIS 103) that the defining factor of a structured programming logic is that each control structure has exactly 1 entry point and 1 exit point. How do the 'break' and 'continue' statements, used in loop structures, that we learn about in Chapter 4, affect structured programming logic? (2 points, write answer in text box)

Submit SalaryCalcLoop.java

Update SalaryCalc.java (Salary Calculator) from last week to now continue to take input for every employee in a company, and display their information until a sentinel value is entered (pg. 219), that exits the loop and ends the program.

(First Part Already completed)

import java.util.Scanner;

public class SalaryCalc {
double Rpay = 0, Opay = 0;

void calPay(double hours, double rate) {
if (hours <= 40) {
Rpay = hours * rate;
Opay = 0;
} else {
double Rhr, Ohr;
Rhr = 40;
Ohr = hours - Rhr;
Rpay = Rhr * rate;
Opay = Ohr * (1.5 * rate);
}
}

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String name;
int shift = 0;
Double rate, hours;
System.out.println("Pay Calculator");
String ch = "";
//added loop here to take the inputs repetedly
do {
System.out.println("Enter Your Name");
name = sc.next();
System.out.println("Enter Your Shift, Enter 0 for Day, Enter1 for Night");
System.out.println("0=Day, 1= Night");
shift=sc.nextInt();
System.out.println("Enter Number of Hours Worked");
hours = sc.nextDouble();
System.out.println("Enter Hourly Pay");
rate = sc.nextDouble();
SalaryCalc c = new SalaryCalc();
c.calPay(hours, rate);
Double Tpay = c.Rpay + c.Opay;
System.out.println();
System.out.println("Calculate Pay");
System.out.println("Employee Name: " + name);
System.out.println("Employee Regular Pay: " + c.Rpay);
System.out.println("Employee Overtime Pay: " + c.Opay);
System.out.println("Employee Total Pay: " + Tpay);
if (shift == 0) {
System.out.println("Employee PayPeriod is Friday");
} else {
System.out.println("Employee PayPeriod is Saturday");

Write a well-documented (commented) program, “ISBN,” that takes a 9-digit integer as a command-line argument, computes the checksum, and prints the ISBN number.

You should use Java’s String data type to implement it. The International Standard Book Number (ISBN) is a 10-digit code that uniquely specifies a book. The rightmost digit is a checksum digit that can be uniquely determined from the other 9 digits, from the condition that d1 + 2d2 +3d3 + ... + 10d10 must be a multiple of 11 (here di denotes the ith digit from the right).

The checksum digit d1 can be any value from 0 to 10. The ISBN convention is to use the character X to denote 10. The checksum digit corresponding to 032149805 is 4 since 4 is the only value of x between 0 and 10 (both inclusive), for which 10·0 + 9·3 + 8·2 + 7·1 + 6·4 + 5·9 +4·8 +3·0 + 2·5 + 1·x is a multiple of 11.

Sample runs would be as follows.

>java ISBN 013376940
The ISBN number would be 0133769402

>java ISBN 013380780
The ISBN number would be 0133807800

A.Write a program that prompts for and reads the user’s first and last name (separately).Then print the initials with the capital letters. (Note that we do not expect that inputs from users are case-sensitive. For example, if the user’s input of the first name is robert and of the last name is SMITH, you should print R.S.)

B.Write a program that creates and prints a random phone number of the form XXX-XXX-XXXX. Include the dashed in the output. Do not let the first three digit contain an 8 or 9 (but don’t be more restrictive than that), and make sure that the second set of three digits is not greater than 655. Hint: Think through the easiest way to construct the phone number. Each digit does not have to be determined separately.
