not self-descriptive, how many bytes it takes?
it takes 2 less chars per for loop? what is the question?
2.may clash with one letter variables
then don't use f for any other variables.
3. is only 1 char shorter to type than u8
yeah but you typed u8 twice in your code but there are lots of for loops.
