A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10. Required:List different ways that this program can be sabotaged so that during execution it computes a different sum, such as 3 to 20.

Given integer values for red, green, and blue, subtract the gray from each value.Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus(255, 0, 0) is bright red, (130, 0, 130) is a medium purple,(0,0,0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50,130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).Given values for red, green, and blue, remove the gray part.

As a twist on the Hello World exercise, you are going to be the end user of the Hello class. This class is designed to greet the user in a variety of world languages. For this task, complete the following:Use the Scanner class to ask the user for their name. Create a Hello object by passing the name to the constructor. Call at least 3 methods from the Hello class to print the greeting in 3 different languages. Remember to write your code in the HelloTester class, but make sure you take a look at the Hello class so that you know the names of the methods you need to use.

Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program:4 of Diamonds8 of SpadesQueen of Clubs8 of HeartsNumber of picks: 9

Scenario: You are part of an IT group managing Active Directory for a mid-size organization. A contracted research group with their own IT team operating from a remote location with a slow network connection has requested that they be able to setup a Child Domain in your organization's domain. The remote IT teams argument is based on their slow network, and their need to access and administer the local server that would need to exist in their remote location. Your team is split between allowing the Child Domain or recommending an Organizational Unit and delegating the remote IT team access. Yours is the deciding vote -- and cost is being considered a deciding factor. What option do you support as the best option in this scenario? What DC configuration for the remotely located server would be the best option? If instead of cost, the deciding factor was the slow speed of their network, what option would you support as the best option?

Easter Sunday is the first Sunday after the first full moon of spring. To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800: 1. Let y be the year (such as 1800 or 2001). 2. Divide y by 19 and call the remainder a. Ignore the quotient. 3. Divide y by 100 to get a quotient b and a remainder c. 4. Divide b by 4 to get a quotient d and a remainder e. 5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder. 6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient. 7. Divide c by 4 to get a quotient j and a remainder k. 8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder. 9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient. 10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder. 11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient. Then Easter falls on day p of month n. For example, if y is 2001: a = 6 h = 18 n = 4b = 20, c = 1 j = 0, k = 1 p = 15d = 5, e = 0 m = 0 g = 6 r = 6Therefore, in 2001, Easter Sunday fell on April 15. Write a program that prompts the user for a year and prints out the month and day of Easter Sunday.Part 1: Problem-Solving PhaseUsing the Design Recipe, write each of the following for this problem:ContractPurpose StatementExamples, making sure to include counter-examplesAlgorithm (based on the above algorithm, completed with input/output steps)Make sure to test your algorithm by hand with the examples to verify it before continuing to Part 2.Part 2: Implementation PhaseUsing Eclipse, write the Java program for the algorithm formulated in Part 1, and test your program with the examples from Part 1.Make sure to incorporate your Contract, Purpose Statement and Examples as one or more comment blocks, and your Algorithm as line comments in your Java source code.
