CF2170A.Maximum Neighborhood
Maximum Neighborhood
Consider an grid filled with numbers as follows:
- the first row contains integers from to from left to right;
- the second row contains integers from to from left to right;
- this pattern continues until the -th row, which contains integers from to from left to right.
Let's define the cost of a cell as its value plus the sum of its neighboring cells' values. Two cells are considered neighboring if they share a side.
Your task is to calculate the maximum cost among all cells in the grid.
The grid for and the optimal answer for it. The yellow cell has the maximum possible cost; the green cells are its neighbors. The cost of the cell is .
Input
The first line contains a single integer () — the number of test cases.
The only line of each test case contains a single integer ().
Output
For each test case, print a single integer — the maximum cost among all cells in the grid.
Note
In the first example, there is only cell with the cost .
In the second example, the cell with value has the maximum cost: .
In the third example, the cell with value has the maximum cost: .
In the fourth example, the cell with value has the maximum cost: .
In the fifth example, the cell with value has the maximum cost: .
