#870
Se consideră un depou de cale ferată precum cel din imagine:
Pe linia A se află n vagoane, numerotate cu valori distincte de la 1 la n, într-o ordine oarecare. Vagoanele trebuie mutate pe linia C, în ordinea 1 2 .. n. Pentru aceasta se poate muta câte un vagon de pe o linie pe alta, în ordinea indicată de săgeți:
A -> B, A -> C sau B -> C.
Să se determine o succesiune de operații care să mute toate vagoanele de pe linia A pe linia C în ordinea dorită.

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 Depou 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.
