Clepsidra
#1118

Un graf conex cu N noduri și M muchii poate fi privit ca o clepsidră cu centrul în nodul X, 1 ≤ X ≤ N, dacă putem împărți toate nodurile, mai puțin nodul X, în două submulțimi nevide astfel încât orice drum de la un nod dintr-o mulțime la un nod din cealaltă mulțime trece prin nodul X. Voi trebuie să determinați numărul de moduri distincte în care putem privi graful ca o clepsidră pentru fiecare din cele N noduri alese drept centru, modulo 666013. Două moduri se consideră distincte dacă cele două submulțimi aferente sunt diferite. Ordinea submulțimilor într-un mod este relevantă, dar ordinea nodurilor în cadrul unei mulțimi nu este. Spre exemplu, soluțiile ({1,2,3}, {4,5}) şi ({4,5}, {1,2,3}) sunt distincte, dar soluţiile ({4,5}, {1,2,3}) şi ({4,5}, {1,3,2}) nu sunt distincte.

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 Clepsidra 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.

Du-te sus!
