Solution

Binary numbers are rather easy to understand, even if becoming familiar with them requires some time. I expect you to have knowledge of the binary numeral system. If you need to review them just take a look at the Wikipedia entry or one of the countless resources on Internet.
The package we are going to write will provide a class that represents binary numbers (Binary) and a class that represents binary numbers with a given bit size (SizeBinary). They shall provide basic binary operations like logical (and, or, xor), arithmetic (addition, subtraction, multiplication, division), shifts and indexing.
