#2187 expand

Ana şi Bogdan au inventat un nou joc, pe care l-au numit Expand. Jocul are N cartonaşe, pe fiecare cartonaş fiind scrisă o literă şi o secvenţă formată din două sau trei litere. O mutare constă în utilizarea unui cartonaş prin care o singură apariţie a literei scrisă pe cartonaş va fi înlocuită în cuvântul curent cu secvenţa corespunzătoare de pe cartonaş. Apoi cartonaşul este repus în joc, astfel că acelaşi cartonaş poate fi utilizat de oricâte ori. Iniţial Ana alege o literă şi un cuvânt. Bogdan trebuie să obţină cuvântul spus de Ana, plecând de la litera respectivă, efectuând un număr minim de mutări. Scrieţi un program care determină numărul minim de mutări necesare pentru a obţine din litera aleasă de Ana cuvântul dat.

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 expand 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.
