BSPRIME - Binary Sequence of Prime Number |
Binary Sequence of Prime Number is a binary sequence that created by converting prime number to base-2 (without leading zeros):
- (2)10=(10)2
- (3)10=(11)2
- (5)10=(101)2
- (7)10=(111)2
- ...
If all base-2 of prime number joined, then we get the binary sequence like this: 10111011111011110110...
Now your task is to count how many digit '1' appear in the first N terms of the sequence, example:
- If N=3, digit '1' appear 2 times: 101110...
- If N=10, digit '1' appear 8 times: 1011101111101...
Input
The first line is an integer T (1 ≤ T ≤ 50,000), denoting the number of test cases. Then, T test cases follow.
For each test case, there is an integer N (0 ≤ N ≤ 150,000,000) written in one line.
Output
For each test case, output the number of digit '1' appear in the first N terms of the sequence
Example
Input: 3 3 10 50 Output: 2 8 36

Wow, @Tjandra, Thanks for this problems. It showed me how I can optimize my Sieve algos. By the way, if you like Number theory problems, you should be interest in HS12PRIM ;-)) Ans: Congratulations, and Thanks for your appreciation :-) Last edit: 2013-01-06 23:18:30 |

Good problem, but unfortunantly Atkin Sieve gets TLE (( |
