`#1045` Imprimanta

Cif-Oji6 este o imprimantă matriceală numită şi imprimantă cu ace, deoarece tipărirea se realizează prin impactul acelor capului de imprimare pe o bandă cu tuş.
Acele sunt aranjate într-o grilă dreptunghiulară formată din 5 rânduri de ace, pe fiecare rând aflându-se la distanţe egale câte 3 ace, aşa cum se observă în figura alăturată.
Prin acţionarea diferitelor combinaţii de ace din grilă, se defineşte forma fiecărei cifre ce permite tipărirea acesteia prin puncte, în felul următor:

De exemplu, cifra 2 va fi tipărită prin 11 puncte ca rezultat al acţionării a 11 ace din grilă: din primul rând de ace al grilei se vor acţiona toate cele 3 ace, din următorul rând doar acul din dreapta, apoi de pe următorul rând toate cele 3 ace, apoi acul din stânga de pe penultimul rând iar din ultimul rând toate cele 3 ace.

a) Ştiind că imprimanta Cif-Oji6 a tipărit numărul N, determinaţi care este cea mai mare cifră a numărul N pentru care s-a acţionat un număr minim de ace ale grilei.
b) Ştiind că imprimanta mai are tuş pe bandă doar pentru imprimarea a K puncte, determinaţi cel mai mare număr natural ce poate fi tipărit prin exact K puncte.

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 Imprimanta 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.
