#4475 Livada3

Fermierul Petrică deține o livadă de formă dreptunghiulară, împărțită în N×M sectoare, dispuse pe N linii și M coloane, in fiecare sector fiind plantat un arbore dintr-o anumită specie, identificată printr-o literă mare a alfabetului englez.

Vecinul său, fermierul Ion dorește să cumpere o zonă dreptunghiulară din livada lui Petrică, care să aibă suprafața S și pentru fiecare specie prezentă în acea zonă numărul de arbori să fie același.

Determinați în câte moduri se poate alege zona dorită de Ion, precum și o modalitate de alegere.

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 Livada3 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.
