There are N people in a room.
Your task is to find the number of ways to divide the people of the room into two groups A and B, such that each group contains at-least one member.
As the number of ways can be large, print output modulo \(10^{9}+7\).
Input format
- First line contains the number of test cases, T.
- Next T lines contains N denoting the number of people in a room.
Output format
For each test case, print the number of ways as modulo \(10^{9}+7\) in a new line.
Constraints
\(1 \le T \le 10^{5}\)
\(1 \le N \le 10^{9}\)
