Hint

Definition of “reverse” in this problem

Suppose the original number has $f$ digits: the highest digit is $a_1$, the second digit is $a_2$, $\ldots$, and the $f$-th digit is $a_f$.

Then the reversed number also has $f$ digits: the highest digit is $a_f$, the second digit is $a_{f - 1}$, $\ldots$, and the $f$-th digit is $a_1$.

Constraints

For $100\%$ of the testdata, $100 \le a, b \le 999$, and $a, b$ do not contain the digit $0$.
