#1101 Project Management

La o firmă de software se lucrează la un mare proiect. Proiectul constă în executarea a n (n număr natural) faze de dezvoltare, numerotate cu numerele 1, 2, …, n. Unele faze pot fi executate în paralel (în acelaşi timp), însă executarea altor faze nu poate fi începută până când nu se finalizează executarea anumitor faze.

Să se scrie un program care să se determine:

a) timpul minim t în care se poate finaliza executarea proiectului
b) pentru fiecare fază k (k din {1,2,…,n}), momentul de timp ck la care poate începe faza k cel mai devreme, respectiv momentul de timp dk la care poate începe faza k cel mai târziu, fără a influenţa durata totală de executare a proiectului.

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 Project Management 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.
