algorithm using pseudocode and top-down, stepwise refinement. - 3. Write a Java
program. - 4. Test, debug and execute the Java program.
- 5. Process three complete sets of data.
(Sale Commission Calculator) A large company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who sells $5,000 worth of merchandise in a week receives $200 plus 9% of $5,000, or a total of $650. You’ve been supplied with a list of the items sold by each salesperson. The values of these items are shown in Fig. 4.33. Develop a Java application that inputs one salesperson’s items sold for last week and calculates and displays that salesperson’s earnings. There’s no limit to the number of items that can be sold.

Question 4 - Algorithm Design
Imagine you are a treasure hunter standing at one side of the river. There are n (a positive
integer) stones on the river. They are aligned on a straight line and at the nth stone, there is
treasure waiting for you. Your target is to reach the nth stone. For each move, you have the
choice of either walking (move one stone ahead) or leaping (move two stones ahead). Also, you
are not allowed to travel backwards. Design an algorithm that calculates the number of ways
(sequences of walks/leaps) that get you to the treasure stone. You should clearly explain the
algorithm and demonstrate the correctness of the algorithm with a complete proof.
Here is an example. For n =
1
5, there are 8 ways:
Method 1: walk → walk → walk → walk → walk
Method 2: walk → walk → walk → leap
Method 3: walk → walk → leap → walk
Method 4: walk → leap → walk →
walk
walk
Method 5: leap → walk → walk →
Method 6: leap → leap walk
Method 7: leap → walk → leap
Method 8: walk → leap leap

If we represent a graph G = V (V, E) in which set of vertices are home of each Friend and an edge represents a path between two homes. Provide the adjacency matrix of directed graph of the graph G. b. In above directed graph G. You are required to devise an algorithm to find all possible paths.arrow_forwardWhen you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forward(Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:arrow_forward
- 15. Write a program to implement and test the algorithm that you designed for Exercise 15 of Chapter 1. (You may assume that the value of . In your program, declare a named constant PI to store this value.)arrow_forward(Thermodynamics) a. Design, write, compile, and run a program that determines the work,W, performed by a piston engine providing a force of 1000 N over a distance of 15 centimeters. The following formula is used to determine the work performed: W=Fd F is the force provided by the piston in Newtons. d is the distance the piston moves in meters. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the work performed by six pistons, each providing a force of 1500 N over a distance of 20 centimeters.arrow_forward(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.arrow_forward
- (Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft). Eisthemodulesofelasticity( lbs/f t 2 ).Iisthesecondmomentofinertia( f t 4 ). For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ftarrow_forward(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.arrow_forward(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.arrow_forward
