It would be a fairly simple task to write a StringBuilder or FastCat

A better choice would be

But wasn't the point to work with byte[] instead of String/char[] ?
Was it?
He said that the task is "to write a StringBuilder or FastCat".
Not really.
That was the first part of what he said that you just arbitrarily
truncated.
I don't know what a
"FastCat" is, but a 'StringBuilder' needs encodings.
True. But byte[] does not.
So 'byte[]' is a case of
being
focused on implementation rather than goal,
It asked for a StringBuilder for byte[]. That is a goal.
It seems weird to me to assume that he want something else than
what he asked for.
So I have to ask, if your goal is to build a 'String', why would you
use 'byte' when 'char'
is for that purpose?
There are not really any indication that he want to build a String.
There is every indication that he want to build a byte array.
When somebody ask for "Type1Something for Type2" it seems
natural to assume that they want "Type2Something" and a
ByteArrayBuilder would produce a byte array.
I presume to conclude that Roedy screwed up on that one.
It happens.
But I doubt it is the case this time.
