This looks odd. Why is it computing something so specific? You will
want to read 5 numbers on every line so surely there will be a function
to read 5 numbers. The various calculations will then be separate
functions that are passed the numbers in an array.

Why are you interested in non-spaces? Nothing in your specification
seems to need non-spaces. Can you write out what the input should look
like in general? I.e. what will you permit and what won't you permit?
