#1218

În satul vecin există un teren agricol de formă dreptunghiulară împărțit în N*M pătrate elementare identice, dispuse alăturat câte M pe fiecare rând şi câte N pe fiecare coloană. Rândurile sunt numerotate de la 1 la N, iar coloanele de la 1 la M. Un pătrat elementar situat în teren pe rândul R și coloana C este identificat prin coordonatele (R,C).

Suprafețe dreptunghiulare din teren (formate fiecare din unul sau mai multe pătrate elementare alăturate) sunt revendicate de T fermieri din sat, în calitate de moștenitori, pe baza actelor primite de la strămoșii lor. Pentru că au apărut și acte false, s-a constat că pot exista mai mulți fermieri care revendică aceleași pătrate elementare.

În cele T acte ale fermierilor, suprafețele dreptunghiulare sunt precizate fiecare prin câte două perechi de numere (X,Y) și (Z,U), reprezentând coordonatele primului pătrat elementar din colțul stânga-sus al suprafeței (rândul X și coloana Y), respectiv coordonatele ultimului pătrat elementar situat în colțul dreapta-jos al suprafeței (rândul Z și coloana U).

Scrieţi un program care să citească numerele naturale N, M, T, R, C apoi cele T perechi de coordonate (X,Y) și (Z,U) precizate în acte (corespunzătoare suprafețelor dreptunghiulare revendicate) și care să determine:

  1. numărul fermierilor care revendică pătratul elementar identificat prin coordonatele (R,C);
  2. numărul maxim de fermieri care revendică același pătrat elementar;
  3. numărul maxim de pătrate elementare ce formează o suprafață pătratică nerevendicată de niciun fermier.

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 Teren 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!
