`#2968` conexidad

Fie un graf neorientat cu N noduri și M muchii, care NU este conex. Să i se adauge grafului un număr minim de muchii, astfel încât acesta să devină conex. Fie extra_i numărul de muchii nou-adăugate care sunt incidente cu nodul i, iar max_extra cea mai mare dintre valorile extra₁, extra₂,… , extra_N. Mulțimea de muchii adăugate trebuie să respecte condiția ca valoarea max_extra să fie minimă.

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:

probleme la care rezolvarea presupune scrierea unui program complet
probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.

Problema conexidad face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:

Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.

Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
