Tema loves cinnabon rolls — buns with cinnabon and chocolate in the shape of a "snail".

Cinnabon rolls come in different sizes and are square when viewed from above. The most delicious part of a roll is the chocolate, which is poured in a thin layer over the cinnabon roll in the form of a spiral and around the bun, as in the following picture:

 Cinnabon rolls of sizes 4, 5, 6

For a cinnabon roll of size $n$ , the length of the outer side of the square is $n$ , and the length of the shortest vertical chocolate segment in the central part is one.

Formally, the bun consists of two dough spirals separated by chocolate. A cinnabon roll of size $n + 1$ is obtained from a cinnabon roll of size $n$ by wrapping each of the dough spirals around the cinnabon roll for another layer.

It is important that a cinnabon roll of size $n$ is defined in a unique way.

Tema is interested in how much chocolate is in his cinnabon roll of size $n$ . Since Tema has long stopped buying small cinnabon rolls, it is guaranteed that $n \ge 4$ .

Answer this non-obvious question by calculating the total length of the chocolate layer.

The first line of the input contains a single integer $t$ ( $1 \le t \le 10^5$ ) — the number of test cases.

The following $t$ lines describe the test cases.

Each test case is described by a single integer $n$ ( $4 \le n \le 10^9$ ) — the size of the cinnabon roll.

Output $t$ integers. The $i$ -th of them should be equal to the total length of the chocolate layer in the $i$ -th test case.
