Ghiocel

#4064

Într-un oraș sunt n case numerotate de la 1 la n. Între anumite case sunt străzi bidirecționale. În casa cu indicele g locuiește Ghiocel. El are k colege ale căror numere de casă îi sunt cunoscute și Ghiocel dorește să le ducă ghicei la inceputul lunii martie. Pentru că este leneș, Ghiocel se decide să ducă ghiocei colegei sau colegelor care stă (stau) la o casă până la care Ghiocel are de parcurs un număr minim de străzi. Ajutați-l pe Ghiocel să determine numerele acestor case.

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 Ghiocel 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!
