#1052 Chibrituri

Lui Gigel, elev în clasa a V-a, îi place grozav de tare să se joace cu cifrele, cu numerele şi creează tot felul de probleme pe care apoi încearcă să le rezolve. Acum se joacă cu o cutie de chibrituri şi formează cu ele cifre. Apoi privirea i-a căzut pe cadranul unui ceas electronic şi a văzut că cifrele sunt formate din segmente orizontale şi verticale şi a început să formeze cu chibriturile cifrele care indică ora (vezi figura). Şi imediat şi-a pus o întrebare: “oare dacă am n chibrituri puse vertical şi m chibrituri puse orizontal, care este ora minimă pe care o pot forma cu aceste chibrituri?”

Fiind date un număr n de chibrituri verticale şi un număr m de chibrituri orizontale, să se scrie un program care determină numărul de ore posibile, ora minimă şi ora maximă care se pot forma cu aceste chibrituri, în modul indicat mai sus, utilizând toate chibriturile respective şi nemodificând orientarea acestora.

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 Chibrituri 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.
