## Problem Description

Mice are lazy. But if you think about it, lazy people get more things done than those who laborously do things. Such as trying to encrypt a string. Others will take a pen and paper and slowly work though the steps to encrypt it. But Squeaky Mouse will create a program to do the job for him.

So, as it seems, Squeaky has found a huge stash of cheese, and he wants to tell his best friend Squealy about it. As this is a top-secret mission, Squeaky uses a custom method to encrypt his message. Since other advanced encryption methods are hard to understand and usually comes with a bunch if Wikipedia-ish gibberish, he will derive his encryption method from the simple ROT-13 method.

ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the letter 13 letters after it in the alphabet. ROT13 is an example of the Caesar cipher, developed in ancient Rome.~ Wikipedia

So A gets replaced by N and N gets replaced by A, and so on.

Squeaky will supply the message in chunks, and occasionally, you will be asked to encrypt the message so far using ROT-13 encryption.

As the resulting encrypted message may be very long, you will convert each character to a number (A = 1, B = 2, ..., Z = 26) and output the sum of all the numbers.

## Input

There is only one line. It will be in this format:

<*char*_{1}>[*length*_{1}][!]<*char*_{2}>[*length*_{2}][!]...<*char*_{n}>[*length*_{n}][!]

"<>" denotes a required field, "[]" denotes an optional field.

*char* is a single lowercase character from *a* to *z*.

*length* is a integer which is the number of copies of *char* to add to the back of the message string. If it is not specified, it means only one copy of *char* is added to the message string. *length* will be at most 1000000.

An exclamation mark (!) denotes that ROT-13 encryption should be applied onto the whole message so far.

Examples are below.

## Output

The output should contain exactly one integer, the sum of all the numbers after converting each character to a number.

## Limits

Let *L* be the length of the input string.

0 < *L* ≤ 10^{6} for all subtasks.

Subtask 1 (10%): *length* will never be specified; there will be no exclamation marks.

Subtask 2 (30%): *length* will never be specified.

Subtask 3 (20%): there will be no exclamation marks.

Subtask 4 (40%): no further restructions.

Subtask 5 (0%): Sample

## Sample Input 1

ab3!c!d4t!

## Sample Output 1

137

## Sample Input 2 (satisfies subtask 2)

ter!hello!p

## Sample Output 2

150
