Large Digits

题目描述

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 $S(B)$.

输入格式

Input is given from Standard Input in the following format: $A$ $B$

输出格式

Print the value of the greater of $S(A)$ and $S(B)$.
If these are equal, print $S(A)$.

123 234

9

593 953

17

100 999

27

提示

All values in input are integers. $100 \le A, B \le 999$We have $S(123) = 1 + 2 + 3 = 6$ and $S(234) = 2 + 3 + 4 = 9$, so we should print the greater of these: $9$.
