- Introduction Some number of teams are participating in a race. You are not told how many teams are participating but you do know that: Each team has a name, which is one of the uppercase letters A-Z. No two teams have the same name, so there are a maximum number of 26 teams. Each team has the same number of members. No two runners cross the finish line at the same time – i.e. there are no ties. At the end of the race we can write the results as a string of characters indicating the order in which runners crossed the finish line. For example: ZZAZAA We can see there were two teams: A and Z. Team A’s runners finished in 3rd, 5th and 6th place. Team Z’s runners finished in 1st, 2nd and 4th place. Scoring the race Each runner is assigned a score equal to their finishing place. In the example above team Z’s runners achieved scores of 1, 2 and 4. Team A’s runners scores were 3, 5, and 6 respectively. The team’s score is the sum of the members score divided by the number of people on…arrow_forwardThe simplest income tax calculation for a single person filing federal income taxes in the United States involves applying a standard deduction, personal exemption and marginal tax rates to the annual income of the taxpayer. For tax year 2015, the standard deduction for an individual was $6300 and the personal exemption was $4000. The 2015 tax rates vary by income bracket and are given in the table below. Tax Rate 10% 15% 25% 28% 33% 35% 39.6% which equals $6203.50. You can calculate an "effective tax rate" based on the original income as Income Range $0.01-$9,225.00 $9,225.01-$37,450.00 $37,450.01-$90,750.00 $90,750.01-$189,300.00 $189,300.01-$411,500.00 $411,500.01-$413,200.00 Over $413,200 To compute the tax liability on a given income, first the deduction and exemption amounts are subtracted, then each portion of the income is taxed at the marginal rate according to the table. For example, for an income of $51,939 (US median income in 2014) you first apply the standard $6,300…arrow_forwardQuestion2: Write a program to determine a student's final grade for (Structure, Strength of materials, and Engineering Mathematics) indicate whether it is passing or failing.

- Age Write a program that requests your date of birth as input and tells your age. Hint:Use the DateDiff function with the DateInterval.Year option, and then use an If block tomodify the result. See Fig. 4.23 and the note in Exercise 40.arrow_forwardProblem Description: Standard telephone keypads contain the digits zero through nine. The numbers two through nine each have three letters associated with them (Fig. 1). Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers. For example, a person whose telephone number is 686-2377 might use the correspondence indicated in Fig. 1 to develop the seven-letter word “NUMBERS.” Every seven-letter word corresponds to exactly one seven-digit telephone number. A restaurant wishing to increase its takeout business could surely do so with the number 825-3688 (i.e., “TAKEOUT”). Fig. 1: Telephone keypad digits and letters. Every seven-letter phone number corresponds to many different seven-letter words, but most of these words represent unrecognizable juxtapositions of letters. It’s possible, however, that the owner of a barbershop would be pleased to know that the…arrow_forwardModify the BarChart program from Chapter 6 Exercise 13 to accept the number of points scored by each player in a season. The bar chart displays one asterisk for each 10 points scored by a player. For example, if a player has scored 48 points, then display 4 asterisks. An example of the program is shown below: Enter points earned for the season by Art >> 10 by Bob >> 20 by Cal >> 30 by Dan >> 40 by Eli >> 50 Points for Season (each asterisk represents 10 points) Art * Bob ** Cal *** Dan **** Eli ***** import java.util.Scanner; public class BarChart2 { public static void main (String[] args) { Scanner input = new Scanner(System.in); int artPoints; int bobPoints; int calPoints; int danPoints; int eliPoints; final int AMT_EACH_ASTERISK = 10; System.out.println("Enter points earned for the season"); System.out.print(" by Art >> "); artPoints = input.nextInt();…arrow_forward
- Task using C language Two spacecrafts are traveling at different speeds from Earth to Mars. While spacecraft A doubles its speed every day, spacecraft B triples its speed in the same period. Given their initial speeds, your task is to determine how many days spacecraft B will take to travel faster than spacecraft A. If the initial speed of spacecraft A is 7, it will be 14 after 1 day, 28 after 2 days, and so on. If the initial speed of spacecraft B is 4, it will be 12 after 1 day, 36 after 2 days, and so on. If the initial speed of spacecrafts A and B are 7 and 4, respectively, B will be faster than A after 2 days, as the speed of A will be 28 and the speed of B will be 36. Requirements Follow the format of the examples below. You will be given several test cases in a single run, and you must provide an answer for all of them. Use #define Examples (your program must follow this format precisely) Example #1 Number of cases: 3Speed of A: 7Speed of B: 4Case #1: 2 day(s)Speed of A:…arrow_forwardGrowth of an Investment Suppose a fixed amount of money is deposited at the beginning of each month into an investment paying 6% interest compounded monthly. After each deposit is made, [new balance]=1.005∗[previous balance one month ago]+ [fixed amount].

- Software Sales (see Chapter 3, Programming Exercises 12): A software company sells a package that retails for $99. Quantity discounts are given according to the following table: Quantity Discount 10–19 10% 20–49 20% 50–99 30% 100 or more 40% Write a program that asks the user to enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount. Submit: Algorithm, Python code with documentation, Outputarrow_forwardInterest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.arrow_forward10. The algorithm shown in Figure 1-13 should calculate and print the gross pay for five workers; however, some of the instructions are missing from the algorithm. Complete the algorithm.
