Rezumat problemă

Undeva, în deșertul Sahara, ilustrul biolog Sahraa Gaea a conceput și construit un sistem de irigații ingenios, sistem cu care își propune să irige o zonă deșertică dreptunghiulară bogată în nutrienți minerali. Zona deșertică este împărțită în N*M pătrate de latură unitate. În fiecare pătrat se află un dispozitiv de picurare ce asigură o anumită cantitate de apă în funcție de comanda primită de la centrul de control al sistemului.

Sistemul de irigare este astfel conceput încât să irige (ude), pe baza unor comenzi automatizate, parcele dreptunghiulare ale regiunii deșertice.

Orice parcelă are laturile paralele cu laturile zonei deșertice și este identificată prin coordonatele colțurilor stânga-sus (x1,y1), respectiv dreapta-jos (x2,y2). La fiecare comandă se specifică parcela care va fi udată și cantitatea de apă (exprimată în litri) cu care va fi irigat fiecare pătrat al acesteia.

Un pătrat al zonei deșertice devine fertil dacă acumulează cel puțin Q litri de apă.

Să se determine aria maximă a unei suprafețe conexe fertile. Prin aria unei suprafețe înțelegem numărul de pătrate ce compun suprafața. Orice două pătrate fertile care au o latură comună fac parte din aceeaşi suprafaţă conexă fertilă.

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 Sahara 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!
