Consider a set of mobile computing clients in a certain town who each

poizon [28]

Answer: answer given in the explanation

Explanation:

We have n clients and k-base stations, say each client has to be connected to a base station that is located at a distance say 'r'. now the base stations doesn't have allocation for more than L clients.

To begin, let us produce a network which consists of edges and vertex

Network (N) = (V,E)

where V = [S, cl-l, - - - - cl-n, bs-l - - - - - - bs-k, t]

given that cl-l, - - - - - cl-n represents nodes for the clients

also we have that bs-l, - - - - - bs-k represents the nodes for base station

Also

E = [ (s, cl-i), (cl-i,bs-j), (bs-j,t)]

(s, cl-i) = have capacity for all cl-i (clients)

(cl-i,bs-j) = have capacity for all cl-i clients & bs-j (stations)

⇒ using Fond Fulkorson algorithm we find the max flow in N

⇒ connecting cl-i clients to bs-j stations

like (cl-i, bs-j) = 1

if f(cl-i, bs-j) = 0

⇒ say any connection were to produce a valid flow, then

if cl-i (clients) connected f(s,cl-i) = 1 (o otherwise)

if cl-i (clients) connected to bs-j(stations) f(cl-i,bs-j) = 1 (o otherwise)

f(bs-j,t) = no of clients (cl-i) connected to bs-j

⇒ on each node, the max flow value (f) is longer than the no of clients that can be connected.

⇒ create the connection between the client and base station i.e. cl-l to base bs-j iff f(cl-i, bs-j) = 1

⇒ when considering the capacity, we see that any client cannot directly connect to the base stations, and also the base stations cannot handle more than L clients, that is because the load allocated to the base statsion is L.

from this, we say f is the max no of clients (cl-i) that can be connected if we find the max flow, we can thus connect the client to the base stations easily.

The Speed of Sound (Java Project. Please make it easy to understand. I'm a beginner at this. I believe we are supposed to use a

Ilya [14]

Answer:

The program of this question can be given as:

Program:

//import pacakge for user input.

import java.util.Scanner;

//define class

public class SpeedofSound

{

public static void main(String a[]) //define main function

{

//define variable.

String medium;

double distance,time=0;

//creating Scanner class object for input from user.

Scanner s=new Scanner(System.in);

//print message.

System.out.printf("Enter medium(air,water or steel) : ");

medium=s.nextLine(); //taking input.

//print message.

System.out.printf("Enter the distance that the sound will travel : ");

distance=s.nextDouble(); //taking input.

switch(medium) //checking condtion between range.

{

case "air":

time=distance/1100; //apply formula

break;

case "water":

time=distance/4900; //apply formula

break;

case "steel":

time=distance/16400; //apply formula

break;

default:

System.out.printf("Sorry, you must enter air,water or steel"); //error for invalid input of medium

System.exit(0);

}

System.out.printf("It take "+time+" seconds"); //print final answer.

}

Output:

Enter medium(air,water or steel) : air

Enter the distance that the sound will travel : 200

It take 0.18181818181818182 seconds

Explanation:

In this program first, we import packages for user input. Then we declare the class in the class we declare all the variables and then we create the scanner class object. It is used for taking input from the user. Then we use the switch statement It is used for condition. It works between the ranges. In the switch statement, we apply all the formula that is given in the question. and at the last, we print the output using printf function in java.

. Consider the problem of finding the largest element in a list of n elements. What will be the basic operation of an algorithm

natali 33 [55]

Answer:

Comparison.

Explanation:

When we have to find a largest in a list of n elements.First we have to iterate over the list so we can access all the elements of the list in one go.Then to find the largest element in the list we have to initialize a variable outside the loop with the minimum value possible and in the loop compare each element with this value,if the element is greater than the variable assign the element to the variable.Then the loop will find the largest element and it will be the variable.
