#1187 Roboti1

O firmă de construcţii imobiliare a achiziţionat recent un teren dreptunghiular de dimensiuni N×M. Terenul este împărțit în parcele de dimensiune 1x1. Pe unele dintre cele N×M parcele sunt plantați copaci. Firma dorește construirea unui grandios complex comercial și este necesară defrișarea întregului teren. În acest scop sunt utilizați roboți, fiecare robot având baza un pătrat de latură L. Suprafața defrișată de fiecare robot la un moment dat este chiar aria de acoperire a robotului, L×L. Fiecare robot pătrunde prin colțul stânga sus de coordonate (1, 1), se poate deplasa doar în dreapta și în jos și poate părăsi suprafața numai prin colțul dreapta jos, de coordonate (N, M).

Cunoscând dimensiunile N, M ale terenului și coordonatele parcelelor în care sunt plantați copaci se cere:

1. Numărul minim de roboți necesari defrișării întregului teren.
2. Să se răspundă la Q interogări de forma k, unde k este un număr natural. Pentru fiecare interogare de această formă va trebui determinată latura minimă a unui robot astfel încât să fie necesari pentru defrișare cel mult k roboți.

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 Roboti1 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.
