Solve problem on 79 Project Euler. This is a Graph problem in disguise, so the key is to figure out what is node and what is an edge. In other words, what are the things that have relationships in this problem and what defines their relationships? Once you figure that out, you can use topological sort to solve the problem. Create an account on the site to confirm your answer. You can do this in any language, but a key to solving the problem is finding the indegree of each node. The indegree of a node in a directed graph is the number of edges that have that node as a destination,1 or the number of edges that lead into the node. JUNG has a built in method for graphs to do this. The other thing to keep in mind for JUNG is that you can’t make two edges with the same value. So if you’re using a String to represent edges, you can’t have two edges with the value of "A".

9. average = total/5 10 endwhile 11 print average, highest Exercise 3 Write a program for a system that checks for user authentication. The user must provide a username and password for upto three attempts. The system must check if the username exists in the system. If it exists, display a "Welcome" message. If the username is wrong display the approriate message, "Incorrect username" and allow the user to try again. If the user attempts more than three times, exit the loop and display the message "Login attempted too many times. Please contact your administrator". N.B: Assume the username and password are already pulled from external file as: Username : "XXXX" Password : 2018
User accounts on a computer network require passwords that contain 6 characters: The first character must be an upper-case letter (A-Z), the last character must be a digit (0-9), and the 4 middle characters can be either a lower-case letter (a-z), upper-case letter, or a digit. How many passwords are possible is allowed (repetition of characters is allowed based on the given requirements)? Enter your answer in the box below. Answer =
Q2: Secret Courses Dan's recently announced that he's teaching n top-secret courses next semester. Instead of enrolling in them through ACORN, students need to email Dan to express their interests. These courses are numbered from 1 to n in some arbitrary order. In particular, if a student named s is interested in taking a course c, they need to send an email to Dan containing the message c s. Note that if a student is interested in taking multiple courses, they need to send multiple emails, one per course. Upon receiving a message c s, Dan looks at the list of students already enrolled in course c. If there's already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course. Dan considers two names too similar if and only if they have the same length and differ in at most one letter (note that "a" and "A" are considered the same letter). For example, "Josh" and "Josh" are too similar. "Sam" and…
Lab 02: Splitting a URL into pieces URLS are composed of five pieces: The scheme, also known as the protocol The authority (may further be divided into the user info, the host, and the port) The path The fragment identifier, also known as the section or ref The query string Read-only access to these parts of a URL is provided by nine public methods: getFile(), getHost(), getPort(), getProtocol(), getRef(), getQuery(), getPath(), getUserinfo(), and getAuthority(). Write a Java program which uses these methods to split URLS entered on the command line into their component parts.

A Web site validates a 16-digit ID number based on the following rules - 1. Starting with the leftmost digit, double it and then double every other digit after it. However, if any of the doubled digits is a two-digit number, subtract 9 from it. Then sum these new digits. For instance, if the ID card number is 5866793610024475, then the digits considered are 5, 6, 7, 3, 1, 0, 4, 7, their new replacements are 1, 3, 5, 6, 2, 0, 8, 5 and the sum of the replacement is 30. 1 2 3 4 6. 7 8 9 10 11 12 13 14 15 8. 6. 7 9 3 6 1 4 4 7 5 6 7 1 4 7 5*2-9 6*2-9 7*2-9 3*2 1*2 0*2 4*2 7*2-9 =1 =3 =5 =6 =2 =0 =8 =5 2. Sum together the remaining sever digits from the ID card number. That is, the digits in the odd-numbered positions. With the ID card number above, we obtain 8+6+9+6+0+2+4+5 = 40. 3. Add together the two sums. If the result is a multiple of 10, then accept the ID card number. Otherwise, reject it. We accept the ID card number since 30+40=70, a multiple of 10.

Kroger Co., a large nationwide grocery chain, maintains a customer reward system titled the “Kroger Plus” card. Customers who enroll in this system are entitled to discounts on products at Kroger stores and on gasoline. To earn discounts and other rewards, the shopper must use the “Kroger Plus” card at the time of checkout. The card has a bar code that identifies the customer. This system allows Kroger to determine customer buying patterns and to use the data for data mining. Using a Web search engine, search for “data mining” and “grocery.” In a one (1) page response, describe what types of information grocery stores collect that they can use for data mining purposes. Also, describe how grocery chains use data mining to improve performance.

An ISBN (International Standard Book Number) is a 10 digit number that is used to identify a book. The first nine digits of the ISBN number are used to represent the Title, Publisher and Group of the book and the last digit is used for checking whether ISBN is correct or not. To uniquely identify a book a 10-digit ISBN number is used. The rightmost digit is checksum digit. This digit is determined from the other 9 digits using condition that 10d, + 9dz + 8dg + + d4o must be a multiple of 11 (where d, denotes the i" digit from the right). The checksum digit d; can be any value from 0 to 10: the ISBN convention is to use the value X to denote 10. Write a C program using pointers that receives a 10- digit ISBN, and computes the checksum, and reports whether the ISBN number is correct or not. Example: 007462542X = 10°0 + 9*0 + 8*7 + 74 + 6*6 + 5*2 + 4*5 + 3"4 + 2*2 + 110 = 176 Since 176 leaves no remainder when divided by 11, hence it is a valid ISBN. Note: When the check digit turns out…
