#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 extrai numărul de muchii nou-adăugate care sunt incidente cu nodul i, iar max_extra cea mai mare dintre valorile extra1, extra2,… , extraN. 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.
