SDNU 1537.Tiger Eat People

Description

As we all know, lls is the boss of SDNU ACM Training Team, so many team members may be afraid of him.

But this is not the case, lls is very kindly to us. To show his love to us, he plan to give all of us an "Accepted". The problem shows as follows:

There are n numbers ​.Each time you can choose a subset of them(may be empty), and then add them up.Count how many numbers can be represented in this way.

Input

The first line of the input contains an integer T, denoting the number of test cases.
In each test case, there is a single integers n in one line, as described above.
, ​

Output

For each test case, output one line contains a single integer, denoting the answer.

Sample Input

4
9
7
8
233

Sample Output

512
128
