Rezumat problemă

#4357 Oxford

Premierul Marii Britanii, Rishi Sunak, a decis să reorganizeze structura administrativă a comitatului Oxfordshire. În Oxfordshire sunt prezente N orașe numerotate de la 1 la N, conectate prin M autostrăzi (drumuri unidirecționale ce conectează două orașe). Rishi a hotărât ca toate orașele cu proprietatea că cetățenii tuturor celorlalte orașe pot ajunge în ele prin intermediul autostrăzilor să devină reședințe. Deoarece numărul de orașe și autostrăzi din Oxfordshire este foarte mare, Rishi vă cere ajutorul în rezolvarea a două probleme cheie.
1. Care sunt indicii orașelor reședință din Oxfordshire.
2. Care este distanța minimă de la fiecare oraș până la cea mai apropiată reședință de acel oraș.

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 Oxford 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.
