May 17 '14 at 8:29 comment D.W., this is not a duplicate. This is a completely different question to the problem with similar input conditions.

May 15 '14 at 12:09 comment Your solution seems to be right, but you also use 'concatenation' and 'or' in your solution.. so I do not understand why we can use everything except priority brackets. But if you want to do so, your expression seems to be fine.
May 15 '14 at 11:51 comment Because I was told to use only the star-operator. So there's no solution without using the star-operator only? My solution seems to be Okay. If you see any kind of mistake in my solution, I would be grateful if you tell me about it.
May 15 '14 at 11:38 comment Why should we just use parens in combination with the star-operator?
May 15 '14 at 11:35 comment But how to do this without priority parens ()? Using only iteration parens ()* is allowed.
