Count Set Bits Problem Statement
Given a positive integer N
, compute the total number of '1's in the binary representation of all numbers from 1 to N. Return this count modulo 1e9+7 because the result can be very large.
Input:
The first line contains an integer T
representing the number of test cases.
Each of the next T
lines contains a single integer N
, the value for each test case.
Output:
For each test case, return an integer denoting the count of set bits from 1 to N
modulo 1e9+7.
Output each result on a new line.
Example:
Input:
2
3
5
Output:
4
7
Explanation:
For N = 3
, the numbers are 1 (0b1), 2 (0b10), and 3 (0b11). Total set bits = 4.
For N = 5
, the numbers are 1 (0b1), 2 (0b10), 3 (0b11), 4 (0b100), 5 (0b101). Total set bits = 7.
Constraints:
1 ≤ T ≤ 100
1 ≤ N ≤ 10^9
- Time limit: 1 second
Note:
Implement the function and return the results, as the output mechanism has been handled.
