- In CORAL LANGUAGE please and thank you! Summary: 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. Ex: If the input is: 130 50 130 the output is: 80 0 80 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasingWrite a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.
- 1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…Write a program that reads student scores, gets the best score, andthen assigns grades based on the following scheme:Grade is A if score is ≥ best -5Grade is B if score is ≥best -10;Grade is C if score is ≥best -15;Grade is D if score is ≥best -20;Grade is F otherwise.The program prompts the user to enter the total number of students, and thenprompts the user to enter all of the scores, and concludes by displaying the grades.Here is a sample run: Enter the number of students: 4 ↵EnterEnter 4 scores: 40 55 70 58 ↵EnterStudent 0 score is 40 and grade is FStudent 1 score is 55 and grade is CStudent 2 score is 70 and grade is AStudent 3 score is 58 and grade is C
- in C# Sometimes figuring letter grades is hard. Write a program that asks for, and reads from the user, a midterm exam grade and a final exam grade. Compute the average of those two grades and ouput a letter grade based on the scale shown below. CHALLENGE PROBLEM: One of my graduate school classes modified the above calculation. This professor said that the final grade would be determined by the simple average of the midterm and the final, however, if the student scored better on the final than they did on the midterm, the professor would weight the midterm exam at 25%, and the final exam at 75% when computing the final grade. Modify your code to use this professors modification in determining letter grade. Here is the grading scale:Write a c++ program to assign passengers seats in an airplane. Assume a small airplane with seat numbering as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D 6 A B C D 7 A B C D The program should display the seat pattern, with an 'X' marking the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like this: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D 6 A B C D 7 A B C D After displaying the seats available, the program prompts for the seat desired, the user types in a seat, and then the display of available seats is updated. This continues until all seats are filled or until the user signals that the program should end. If the user types in a seat that is already assigned, the program should say that that seat is occupied and ask…Exercise III: Catalan numbers For n e N, denote by c, to be the number of ways to form a "mountain range" with n upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance: for n = 1, only UD is allowed, so c = 1; • for n = 2, only UUDD and UDUD are allowed, so c2 = 2. 1. Check that c3 = 5 by writing down or drawing all possible options. 2. Consider the power series +00 g(x) = 2 n=0 (by definition co = 1) called the generating function of the sequence (en). Justify that cn < 4" for each n, and deduce that the radius of convergence of g is at least 1/4. 3. It can be show that for r E (-1/4, 1/4), g(x) = 1+ xg(r)? and therefore 1- VI 4.x g(x) = 2.x Use this formula and the known power series of V1+ x to write the first terms of the power series expansion of g, in the form g(x) = co + c1x + c2x2 + C3x + c4x* + ·.. Show how you obtain a few terms, but you do not need to show all computations and you can use a calculator for fractions. Check that you recover co,…
- Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segmentA fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…4- Write a program that reads the average of 30 students and find the number of pass students , the number of fail students then print the results. 5- Write a program that reads 20 numbers then find the number of negative and positive numbers and the number of numbers equal to zero and print the results. 6- Write a program to read three numbers A,B,C then find whether A,B,C can form the sides of a triangle, if yes compute the parameter of the triangle , if no print the massage ( not a triangle), then determine whether A,B,C form the side of an (a)) equilateral triangle ,b) isosceles triangie ,c)) right angle triangle Hint: ( A,B,C can form a triangle if each side is less than the sum of the other two sides)
