MD5 score

You are given strings $S$ and $P$.

Let $A$ be the concatenation of $S$, the character #, and $P$ in that order.

Let $M$ be the MD5 hash of $A$. $M$ is a hexadecimal string of length $32$ that uses the characters $0$ through $9$ and $a$ through $f$.

The score of $M$ is the sum of its digits read as hexadecimal values.

If the hash were 20af3 (a real MD5 hash has length $32$; this shorter string is only to show the arithmetic), the score is $2_{16} + 0_{16} + \mathrm{a}_{16} + \mathrm{f}_{16} + 3_{16} = 2 + 0 + 10 + 15 + 3 = 30$.

Print the score of $M$.

The first line contains the string $S$.

The second line contains the string $P$.

$S$ and $P$ consist of uppercase letters, lowercase letters, and digits. Each has length from $1$ to $10000$.

Print the score of $M$ on the first line.
