#2971

Se dă un arbore cu N noduri, numerotate de la 1 la N. Arborele se va transforma astfel: la oricare etapă fiecare nod de gradul 1 diferit de rădăcină din arborele actual se înlocuiește cu un arbore identic cu cel dat inițial, iar la următoarea etapă procedeul se va relua pentru arborele obținut, formându-se astfel un arbore infinit. În imagini se prezintă un exemplu de arbore dat inițial, arborele obținut după prima etapă de prelungire a frunzelor și arborele obținut după două etape de prelungire a frunzelor. Să se determine câte noduri se află la distanță D de rădăcina arborelui infinit.

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 tairos 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.

Du-te sus!
