- For 4.31 (a) Do not use the passing the baton technique. Solve the problem directly using semaphores. Your answer to Question (a) should be similar to the solution to the Reader/writer's Problem. For Exercise 4.31 (b), you must define the following shared variables/semaphores and use the technique of passing the baton: int nN = 0; // number of northbound cars on the bridge int nS = 0; // number of southbound cars on the bridge sem e = 1; // controls entry to critical section n = 0; // used to delay northbound cars s = 0; // used to delay southbound cars int dn = 0; // number of delayed northbound cars ds = 0; // number of delayed southbound carsarrow_forwardPython question please include all steps and screenshot of code.

Implement the following to simulate how websites ensure that everyone has a unique username.a) Make a list of five or more usernames called current_users.b) Request an input of username.c) Print a message, Sorry XXX, that name is taken and also display the current user list if the inputusername has already been used. XXX is the input user name.d) Print a message, Great, XXX is still available and also display the updated user list if the username hasnot been used.e) Make sure your comparison is case insensitive. If 'John' has been used, 'JOHN' or ‘john’ should not beaccepted.Example Output 1Enter your user name: TOMSorry TOM, that name is taken.Current users: [‘admin’, ‘tom’, ‘jerry’, ‘Dora’, ‘GEORGE’] Example Output 2 Enter your user name: curiousGeorge Great, curiousGeorge is still available.

- 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.arrow_forwardConsider the string from Question1 i.e. inputString = ‘Dell Display Manager’s (DDM) Easy Arrange feature lets you quickly tile and view your applications side by side across one or more connected screens for multitasking efficiency. And with the improved DDM, you’ll get even more preset layouts. The auto-restore feature remembers where you left off, so applications will go back to where you left them, even after you’ve unplugged.’ Use Regular Expressions to write the python code for following” a. Search all appearances of ‘DDM’ in inputString. b. Print a substring/characters that starts with ‘And’ and ends with ‘DDM’ c. Print the position of ‘auto’ d. Print the substring after ‘auto’ e. Take the substring of d. as input and split it where ‘,’ is foundarrow_forwardCompTech a. Create a Ꜫ-NFA for the following RE: (a | ba) ? a (b | ab)* b.

- 09.coded in it When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}') Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65..arrow_forward(C PROGRAMMING ONLY) 5. Preserving the Gene Poolby CodeChum Admin In order to make sure that the future generations will grow into great beings, we must make sure that the gene pool consists of the best genes. In order to do that, we must compare genes from each other and find out which one is the best! Instructions: In the code editor, you are provided with a main() function that asks the user for 4 integer inputs and passes these to the getBest() function call.Your task is to declare and define this getBest() function which has the following details:Return type - intName - getBestParameters - 4 integersDescription - returns the highest integer passedDO NOT EDIT ANYTHING IN THE MAINInput 1. First integer 2. Second integer 3. Third integer 4.

He asked his brother Gabriel to teach him how to count, but he requested to do teach it 10 numbers per line. His brother don't know how to teach his brother so he looking for a friend who can help him. Can you help Gabriel to do a program that can teach Troy to count numbers by printing it 10 numbers per line? If the numbers exceed or is equal to 50, the output should display "Number must be below 50!". Input 1. Size of Numbers Description The size of the numbers. Constraints The value is guaranteed to be a positive integer. Sample 17 Output The first line will contain a message prompt to input the size. The succeeding lines will contain the numbers or the message required if the number is greater than 50.

You are to develop a JavaScript file (problems.js) that contains the implementation of 5functions. Each function is represented as one step, b). Each function is independent and solves a unique problem, as such, treat and implement each function in isolation of the others, that is, you should only focus on one problem at a time. 2).
