PHIPOWER - Power of Phi |
Vertu was very impressed by the golden ratio φ = (1 + √5) / 2 and about it occurring in nature and all that. He now begins to wonder if any non negative integral power of φ is also special. Since he does not like working with decimals, he decided to approximate the positive integral power of φ to its closest integer. Help him by printing the closest integer to φn, given n.
Input
The first line contains t, the number of test cases. t lines follow, each containing one positive integer n.
Output
For each test case, print the closest integer to φn. If you think there are two closest possible integers, print either of them. Print the answer modulo(109+7).
Constraints
t <= 500
0 <= n <= 106
Example
Input: 2 1 3 Output: 2 4

PS: problem setter should set a new problem (and move this one to tutorial) instead of simply changing the constraints and rejudging. The constraints is a part of the problem. |
