For an integer $n$, let $S(n)$ be the sum of digits in the decimal notation of $n$. For example, we have $S(123) = 1 + 2 + 3 = 6$. Given two $3$\-digit integers $A$ and $B$, find the greater of $S(A)$ and $S(B)$. ## Constraints * All values in input are integers. * $100 \le A, B \le 999$ ## Input Input is given from Standard Input in the following format: $A$ $B$ [samples]

Samples

Input #1

123 234

Output #1

9

We have $S(123) = 1 + 2 + 3 = 6$ and $S(234) = 2 + 3 + 4 = 9$, so we should print the greater of these: $9$.

Input #2

593 953

Output #2

Input #3

100 999

Output #3
