Explanation of Solution

Implementation of norm(v):

The norm() method takes the input parameter of “vec” to return the Euclidean norm of “vec” array of coordinates.

//Function definition

public static double norm(double[ ] vec)      

{

/*Call the norm() by passing the “vec” and “2” and return the result of computed value. */

return norm(vec,2);

}

Explanation:

In norm() method,

  • It takes the input parameter of “vec”.
  • Call the norm() method by passing the “vec” and “2” and return the result of computed value of p-norm value of “vec” array of coordinates.

Implementation of norm(v, p):

The norm() method takes the input parameter of “vec” and “pow” to return the p-norm value of “vec” array of coordinates.

//Function definition

public static double norm(double[ ] vec, int pow)

{

//Declare the variables

int sum = 0;

double exp = 1.0/pow;

//Loop executes until from “i” to "vec"

for (double i : vec)

//Add the "sum" and the power of number

sum += Math.pow(i,pow);

//Return the return

return Math.pow(sum, exp);

}

Explanation:

In norm() method,

  • It takes the input parameter of “vec” and “pow”.
  • Loop executes until the “vec” to add the sum and power of input.
  • Return the computed p-norm value of “vec” array of coordinates.

A3Q3.c - You are to write a C program that implements the following disk scheduling algorithms: a. FCFS [10 marks] b. SCAN [10 marks] c. C-SCAN [10 marks] d. SSTF [10 marks] e. LOOK [10 marks] f. C-LOOK [10 marks] • Your program will service a disk with 300 cylinders numbered 0 to 299. • • • • The program will service the requests (a list of 20 cylinder numbers) given in the file request.bin. This file contains (4 byte) integer values representing requests ranging from 0-299. Your program will take the initial position of the disk head as the first command line argument and the direction of the head as the second command line argument. It will then output the requests in the order in which they are serviced, and the total amount of head movements required by each algorithm. In particular, your program needs to do the following: Your program should take two command line arguments a) First command line argument - initial position of the disk head (an integer value) b) Second command line…
