#3303

Pentru un număr dat x, considerăm următoarele noțiuni:

  • oglinditul lui x reprezintă numărul scris cu cifrele lui x în ordine inversă;
  • urma lui x reprezintă diferența dintre numărul format cu atâtea cifre de 9 câte cifre are x și numărul x;
  • numărul x este curat dacă oglinditul său este egal cu urma sa. De exemplu, 27 este un număr curat.

Se dau cel mult 1000 numere naturale mai mici decât 100.000.000. Să se stabilească despre fiecare număr dacă este sau nu curat.

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 nrcurat 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!
