Three r there are's in strawberry.
You are given an array $b$ of length $m$. You can perform the following operation any number of times (possibly zero):
- Choose two distinct indices
$i$and$j$where$\bf{1\le i \lt j\le m}$and$b_i$is even, divide$b_i$by$2$and multiply$b_j$by$2$.
Your task is to maximize the sum of the array after performing any number of such operations. Since it could be large, output this sum modulo $10^9+7$.
Since this problem is too easy, you are given an array $a$ of length $n$ and need to solve the problem for each prefix of $a$.
In other words, denoting the maximum sum of $b$ after performing any number of such operations as $f(b)$, you need to output $f([a_1])$, $f([a_1,a_2])$, $\ldots$, $f([a_1,a_2,\ldots,a_n])$ modulo $10^9+7$ respectively.
Input
The first line contains a single integer $t$ ($1\le t\le 10^4$) — the number of test cases.
The first line of each test case contains a single integer $n$ ($1 \le n \le 2 \cdot 10^5$) — the length of $a$.
The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \le a_i \le 10^9$) — the starting values of array $a$.
It is guaranteed that the sum of $n$ over all test cases will not exceed $2 \cdot 10^5$.
Output
For each test case, output $n$ integers representing the answer for each prefix of $a$ modulo $10^9+7$.
Note
For each prefix in the first example, a possible array after operations is:
$[1]$and the sum is$1$;$[1, 2]$and the sum is$3$;$[1, 1, 6]$and the sum is$8$;$[1, 1, 3, 8]$and the sum is$13$;$[1, 1, 3, 1, 40]$and the sum is$46$;$[1, 1, 3, 1, 5, 48]$and the sum is$59$;$[1, 1, 3, 1, 5, 3, 112]$and the sum is$126$;$[1, 1, 3, 1, 5, 3, 7, 128]$and the sum is$149$;$[1, 1, 3, 1, 5, 3, 7, 1, 1152]$and the sum is$1174$;$[1, 1, 3, 1, 5, 3, 7, 1, 9, 1280]$and the sum is$1311$.
