| "Happy birthday to you... Happy birthday to you... Happy birthday to |
| Grovyle... Happy birthday to you..." |
|
|
| Today is Grovyle's birthday and he is going to invite his friends to his |
| birthday party. To have an awesome party, each of the attendants should get |
| one piece of cake. Your job is to help Grovyle invite as many friends as you |
| can. |
|
|
| However, Grovyle's parents are very mean, and make him use the following rules |
| when cutting his cake: |
|
|
| * There is only ONE cylindrical cake. |
| * Grovyle cuts the cake **N** times, each cut being perpendicular to the surface of the cake. |
| * The **i**-th cut is a broken line with **a**[**i**] vertices. |
| * The knife is only allowed to intersect the edge of the cylindrical cake at the start and end of the cut. |
|
|
| What is the maximum number of pieces Grovyle could get? |
|
|
| ### Input |
|
|
| The first line contains an integer **T**, **T** ≤ 50, indicating the number of |
| test cases. Each test case begins with an integer **N**, 1 ≤ **N** ≤ 100, |
| followed by **N** integers **a**[**i**], 0 ≤ **a**[**i**] < 400, which |
| indicate the number of vertices in the **i**-th cut. |
|
|
| ### Output |
|
|
| For each test case, output "Case #i: " followed by the maximum number of |
| pieces of cake Grovyle can cut. |
