`#2527` hanoi

Turnurile din Hanoi este un joc matematic sau, dacă vreți, un puzzle. Este format din trei tije A, B și C și un număr variabil de discuri, de diferite diametre. Inițial discurile sunt așezate în ordine descrescătoare a diametrelor pe tija A, de la vârf către bază, astfel încât să formeze un turn.
Scopul jocului este acela de a muta toate discurile de pe tija A pe tija C folosind ca tijă intermediară tija B, respectând următoarele reguli:

doar un singur disc poate fi mutat, la un moment dat
fiecare mutare constă în luarea celui mai de sus disc de pe o tija și mutarea acestuia pe o altă tijă
un disc cu diametrul mai mare nu poate fi poziționat deasupra unui disc cu diametrul mai mic.

Cerința

Dacă se cunoaște numărul n de discuri aflate pe tija A, să se determine șirul mutărilor necesare pentru ca toate discurile să fie mutate pe tija C.

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 hanoi 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.
