#2168 dir

Costel trebuie să realizeze, împreună cu echipa sa, o aplicaţie software pentru gestiunea fişierelor de pe hard-disc, sarcina sa fiind aceea de a scrie un modul pentru determinarea căilor tuturor fişierelor de date aflate în structura arborescentă a folderelor de pe disc. Membrii echipei au stabilit o codificare proprie pentru memorarea structurii fişierelor de pe disc, utilizând un şir de caractere. Scrieţi un program care, cunoscând şirul de caractere ce codifică o structură de fişiere de pe disc, determină calea pentru fiecare fişier de date din structură. Prin cale a unui fişier se înţelege o succesiune de foldere, fiecare folder fiind urmat de caracterul \(backslash), începând de la folderul aflat pe cel mai înalt nivel al structurii (primul specificat în şirul ce codifică structura de fişiere), până la subfolderul în care se află fişierul de date respectiv şi terminată cu numele fişierului. Căile determinate vor fi afişate în ordine lexicografică.

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 dir 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.
