# How much is the fish! (- Scooter )
The ocean is full of colorful fishes. We as programmers want to know the hexadecimal value of these fishes.

## Task
Take all hexadecimal valid characters (a,b,c,d,e,f) of the given name and XOR them. Return the result as an integer.

## Input
The input is always a string, which can contain spaces, upper and lower case letters but no digits. 

## Example

`fisHex("redlionfish") -> e,d,f -> XOR -> 12`
