Last year Bob earned by selling memory sticks. During each of n days of his work one of the two following events took place: * A customer came to Bob and asked to sell him a 2x MB memory stick. If Bob had such a stick, he sold it and got 2x berllars. * Bob won some programming competition and got a 2x MB memory ...
