#2309 Competitie

La o competiție au participat N concurenți. Fiecare dintre ei a primit un număr de concurs astfel încât să nu existe concurenți cu același număr. Numerele de concurs aparțin mulțimii {1,2,...,N}. Din păcate, clasamentul final a fost pierdut, iar comisia își poate aduce aminte doar câteva relații între unii participanți (de genul “participantul cu numărul 3 a ieșit înaintea celui cu numărul 5”). Șeful comisiei are nevoie de un clasament final și vă cere să-l ajutați determinând primul clasament în ordine lexicografică ce respectă relațiile pe care și le amintește comisia.

ONI 2001, clasa a IX-a

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 Competitie 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.
