LOVINGPW - Loving Power |
Angel Luis is now getting math class. His teacher is teaching to him the XOR operation:
- 0 XOR 0 = 0
- 0 XOR 1 = 1
- 1 XOR 0 = 1
- 1 XOR 1 = 0
When a number has more than one bit, the operation is applied to all bits. The teacher write two numbers x, y (0 <= x, y <= N) and make the XOR operation between x and y, Angel Luis would like to know how many pairs x, y such x XOR y = 2z where z >= 0.
See that for N = 3:
- 0 XOR 1 = 20
- 0 XOR 2 = 21
- 3 XOR 1 = 21
- 2 XOR 3 = 20
So there are 4 pairs.
Given N you should return the number of pairs modulo 1000000007.
Input
First line contains number t - the number of cases. Following t lines will each have a number N.
t <= 100
N <= 1000000000000000 (1015).
Output
For each case the number of pairs modulo 1000000007.
Example
Input: 3 1 2 3 Output: 1 2 4

Not reading the problem correctly caused me many WAs, the sequence is indeed very nice... :) O/P for 10^15 is 227182119. Finally AC in 0.00s. :) Last edit: 2013-07-18 15:39:53 |
