#4244

Autorităţile dintr-o zonă de munte intenţionează să stabilească un plan de urgenţă, pentru a reacţiona mai eficient la frecventele calamităţi naturale din zonă. În acest scop au identificat N puncte de interes strategic şi le-au numerotat distinct de la 1 la N. Punctele de interes strategic sunt conectate prin M căi de acces având priorităţi în funcţie de importanţă. Între oricare două puncte de interes strategic există cel mult o cale de acces ce poate fi parcursă în ambele sensuri şi cel puţin un drum (format din una sau mai multe căi de acces) ce le conectează.
Autorităţile estimează gravitatea unei calamităţi ca fiind suma priorităţilor căilor de acces distruse de aceasta şi doresc să determine un scenariu de gravitate maximă, în care punctele de interes strategic să fie împărţite într-un număr de K grupuri.

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 urgenta 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!
