#1193 Cabana

Ben are un teren pe care se află o pădure cu arbori seculari. Acolo vrea să-şi construiască o cabană, însă el fiind ecologist nu vrea să taie niciun arbore, ci vrea să găsească cea mai mare suprafaţă dreptunghiulară fără arbori. El caută o suprafaţă dreptunghiulară străjuită doar în colţuri de arbori şi cu laturile paralele cu axele de coordonate. Ben cunoaşte coordonatele tuturor arborilor din pădure şi vă roagă să-l ajutaţi să găsească aria dreptunghiului cu suprafaţă maximă care are arbori doar în cele patru colțuri.

Cunoscând numărul arborilor din pădure şi coordonatele acestora, se cere să se determine aria dreptunghiului de suprafaţă maximă cu copaci doar în cele 4 colţuri, unde Ben intenţionează să-şi construiască cabana.

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 Cabana 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.
