#4096

Un palilindrom este un număr natural pentru care există o bâlbâială a regelui care îl transformă într-un palindrom. Spre exemplu, 25373552 este un palilindrom, pentru că după o bâlbâială poate deveni 255373552, acesta fiind un număr palindrom. Fiind dat un număr natural nenul X să se determine:

• Câte numere diferite poate genera X după o bâlbâială și câte numere diferite pot deveni X după o bâlbâială.
• Cel mai mare număr palilindrom care se poate forma cu cifrele lui X. Nu este obligatoriu să se folosească toate cifrele lui X.
