Definition of "Reversing" in This Problem

Let the original number have $f$ digits, with the highest digit being $a_1$, the second digit being $a_2$, and so on, with the $f$-th digit being $a_f$.

The reversed number will also have $f$ digits, with the highest digit being $a_f$, the second digit being $a_{f-1}$, and so on, with the $f$-th digit being $a_1$.
