CF1809B.Points on Plane
Points on Plane
You are given a two-dimensional plane, and you need to place chips on it.
You can place a chip only at a point with integer coordinates. The cost of placing a chip at the point is equal to (where is the absolute value of ).
The cost of placing chips is equal to the maximum among the costs of each chip.
You need to place chips on the plane in such a way that the Euclidean distance between each pair of chips is strictly greater than , and the cost is the minimum possible.
Input
The first line contains one integer () — the number of test cases. Next cases follow.
The first and only line of each test case contains one integer () — the number of chips you need to place.
Output
For each test case, print a single integer — the minimum cost to place chips if the distance between each pair of chips must be strictly greater than .
Note
In the first test case, you can place the only chip at point with total cost equal to .
In the second test case, you can, for example, place chips at points , and with costs , and . Distance between each pair of chips is greater than (for example, distance between and is equal to ). The total cost is equal to .
In the third test case, you can, for example, place chips at points , , , and . The total cost is equal to .
