Count Set Bits

Try Problem

You are given a positive integer ‘N’. Your task is to find the total number of ‘1’ in the binary representation of all the numbers from 1 to N.

Since the count of ‘1’ can be huge, you are required to return it modulo 1e9+7.

Do not print anything, just return the number of set bits in the binary representation of all integers between 1 and ‘N’.
Input Format:
The first line of input contains an integer ‘T’ denoting the number of test cases to run. 
Then the next ‘T’ lines represent the ‘T’ test cases.

The first line of each test case contains a single integer ‘N’.
Output Format
For each test case, return an integer that is equal to the count of set bits in all integers from 1 to n modulo 1e9+7.

Output for each test case will be printed in a new line.
You do not need to print anything; it has already been taken care of. Just implement the given function.
1 <= T <= 100
1 <= N <= 10^9
