Answer:

A) False

Explanation:

Extranet

An extranet acts as a shared network, disseminating information present on the intranet. That is, if a private intranet shares some of its content with other users (be they sellers, customers, etc.), this shared network is what we call the extranet.

Intranet

Today, companies are looking for tools and methods to align internal communication, reduce costs, and centralize information and files. The intranet is one of these tools, which works restricted to a specific audience, such as a company. This way, collaborators can access it with their specific username and password.

The intranet is, then, a closed and internal network, and still allows the use of more communication protocols besides HTTP. Intranet access is typically done on a local server and a local network, which we call LAN, which means Local Area Network installed within the company.

This internal network connects users, allowing information exchange, file and document management, centralizing communication between users. With this tool, you can quickly and securely and efficiently connect companies and departments.

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.

What's the problem with this code ?
Svet_ta [14]
Hi,

I changed your program using some of the concepts you were trying to use. Hopefully you can see how it works:

#include <string>
#include <iostream>
#include <sstream>
#include <vector>
#include <algorithm>

using namespace std;

int main()
{
   short T;
   cin >> T;
   cin.ignore();

   string str[100];

   for(int i=0; i<T; i++)
   {
      getline(cin, str[i]);
   }

   for (int i = 0; i < T; i++)
   {
      stringstream ss(str[i]);
      string tmp;
      vector<string> v;

      while (ss >> tmp)
      {
          // Let's capitalize it before storing in the vector
          if (!tmp.empty())
          {
              transform(begin(tmp), end(tmp), std::begin(tmp), ::tolower);
              tmp[0] = toupper(tmp[0]);
           }
           v.push_back(tmp);
        }

        if (v.size() == 1)
        {
           cout << v[0] << endl;
        }
        else if (v.size() == 2)
        {
           cout << v[0][0] << ". "  << v[1] << endl;
        }
        else
        {
            cout << v[0][0] << ". " << v[1][0] << ". " << v[2] << endl;
        }
    }

     return 0;
}
