2. Alterna glasses a. There are 2n glasses standing next to each other in a row, the first n of them filled with a soda drink and the remaining n glasses empty. Make the glasses alternate in a filled-empty-filled-empty pattern in the minimum number of glass moves. [Gar78] b. Solve the same problem if 2n glasses–n with a drink and n empty-are initially in a random order.

Solve the question using java as the programing language.

**2. Alternating glasses** **a.** There are \(2n\) glasses standing next to each other in a row, the first \(n\) of them filled with a soda drink and the remaining \(n\) glasses empty. Make the glasses alternate in a filled-empty-filled-empty pattern in the minimum number of glass moves. [Gar78] **Diagram:** The image shows a row of glasses. The initial arrangement consists of \(n\) filled glasses (depicted as shaded) followed by \(n\) empty glasses. An arrow indicates a transformation to an alternating pattern, where the glasses are rearranged to alternate between filled (shaded) and empty (unshaded) along the row. **b.** Solve the same problem if \(2n\) glasses—\(n\) with a drink and \(n\) empty—are initially in a random order.
