Their "magnificence" is quantified by the rather simple process of counting the exact number of tail feathers and multiplying this by the difference in the length of the minimum and maximum lengths of tail feather. You are to write a simple program that will allow the user to enter the length of each tail feather individually and keep on entering feathers until a -1 is entered. The program will then return the quantified "magnificence" factor.arrow_forwardStatic Variable: a variable whose lifetime is the lifetime of the program (static int x;) Dynamic Variable: It is a pointer to a variable (int *x;) Is this comparison true?arrow_forward

The program should define and use 3 functions: distance(x1, y1, x2, y2): computes and returns the distance between two points • area(r): computes and returns the area of a circle with radius r • main(): asks user for input, calls the other functions, and prints the answer. The input and output of the program should look similar to this: X for center point: 0 Y for center point: 0 X for perimeter point: 1 Y for perimeter point: 1 Area of circle centered at (0.0, 0.0) with radius 1.414213 is 6.283185. Hint 1: Area of a circle = n? Hint2: Distance between 2 points = sqrt(x2-X12 + (Y2 - Y1)²) Starter code: import math def distance(x1, y1, x2, y2): #Add code to compute and return distance between (x1, y1) and (x2, y2) def area(r): #Add code to compute and return area of circle…arrow_forwardProblem Description: In the Whimsical Library, each book is enchanted with a magical code to ensure the protection of knowledge. The validation process for these magical codes involves a combination of mathematical spells. The validation process is described as follows: Take the sum of the digits at odd positions from left to right. Take the sum of the squared digits at even positions from left to right. If the absolute difference between the results from step 1 and step 2 is a prime number, the book code is considered valid; otherwise, it is invalid. Example 1: Consider the magical book code 86420137. Step 1. Take the sum of the digits at odd positions from left to right. 8+4+0+3=15 Step 2. Take the sum of the squared digits at even positions from left to right. 6^2+2^2+1^2+7^2=36+4+1+49 = 90 Step 3. If the absolute difference between the results from step 1 and step 2 is a prime number. 115-901 75 (not a prime number) Book code 86420137 is invalid. Example 2: Now, let's examine the…arrow_forward

In that case we want to normalize it to 0 so all grades fall into the range [0, 100]. ex: bound_0_to_100(75) returns 75, bound_0_to_100(103) returns 100, and bound_0_to_100(-5) returns 0arrow_forwardPYTHON HOMEWORK QUESTION def area(side1, side2): return side1 * side2 s1 = 12s2 = 6 Select all statements that correctly call the area function.
