Given a positive integer N denoting the length of a stick, return the number of ways to split a stick into four parts so that it's possible to form a rectangle using these parts, but is impossible to form a square.

**Input:**

The first line contains T denoting the number of testcases. Then follows description of testcases. Each case contains a single positive integer N denoting the length of a stick.

**Output:**

For each test case, output a single line containing the number of ways to form rectangle by splitting given stick.

**Constraints:**

1<=T<=100

1<=N<=10^9

**Example:**

Input :

2

10

20

Output :

2

4

**Explanation:**

In the first example, the 2 ways to split the stick are {1,1,4,4} , {2,2,3,3} .

In the second example, the 4 ways to split the stick are {1,1,9,9} , {2,2,8,8} , {3,3,7,7} and {4,4,6,6}.

Note that {5,5,5,5} forms square so it is not considered.
