#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.
