- Task 03: Read the concept of Binomial coefficient given in chapter-6. Write a method that takes two parameters n and k and returns the value of Binomial Coefficient C(n, k). For example, your function should return 20 for n = 6 and k = 3, and it should return 35 for n= 7 and k = 4. ( confirm it through the Pascal's triangle as given below). 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 15 10 10 5 1 15 (20) 15 6 1 1 7 21 35 (35 21 7 1 1arrow_forwardPlease write in detail.

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_forward
- What is meant by Regular Expression? Why we used it? What is the difference between a regular expression and a descriptive method? Kindly give some examplesarrow_forwardWhat do you mean by "extension" and "intention"?arrow_forwardjava Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.) Design: (Describe the major steps for solving the problem.) Coding: (Go over your code step by step) Testing: (Describe how you test this program). In other words run your code with sample outputs.arrow_forward
- What error message do you see in the Code Pad if you type the following? nd.setValue(int 5); The error message is not actually very helpful at all. Can you work out what is incorrect about this call to setValue, and correct it? It would also be worth remembering this error message because it results from an easy error to make in the early stages of learningarrow_forwardUse the pseudocode methods below to answer the questions starting on the next page.

- Implement the following questions using Python. Make use of conditional and print statements.Make sure to clearly define your variables and don’t forget to indent your code. The logician Raymond Smulyan describes an island containing two types of people:knights who always tell the truth and knaves who always lie. You visit the island and are approached bytwo natives who speak to you as follows:• A says: B is a knight.• B says: A and I are of opposite type.What are A and B?arrow_forwardStatements: Some dogs are bats. Some bats are cats. Conclusions: Some dogs are cats. Some cats are dogs. Group of choices: A. Only (1) conclusion follows B. Only (2) conclusion follows C. Either (1) or (2) follows D. Neither (1) nor (2) follows E. Both (1) and (2) followarrow_forwardWhat are the next three actions you can take if you've tried debugging and are still experiencing problems?arrow_forward
