POWFIB - Fibo and non fibo
The problem is simple.
Find (a^b) % MOD
where,
a = Nth non-fibonacci number
b = (Nth fibonacci number) % MOD
MOD = 10^9+7
Consider fibonacci series as 1,1,2,3,....
Note: It is guaranteed that Nth non-fibonacci number will always be less than MOD value for every value of N used.
Input
First line contains T, the number of test cases.
Each next T lines contains a number N.
Output
Print T lines of output where each line corresponds to the required answer.
Announcement: Constraints are updated. Sorry for inconvenience occurred.
Example
Input: 3 3 2 1 Output: 49 6 4
Explanation
For N=3 : 3rd non fibo number = 7, 3rd fibo number = 2. ans = (7^2) %MOD = 49
For N=2 : 2nd non fibo number = 6, 2nd fibo number = 1. ans = (6^1) %MOD = 6
For N=1 : 1st non fibo number = 4, 1st fibo number = 1. ans = (4^1) %MOD = 4
For N=1 : 1st non fibo number = 4, 1st fibo number = 1. ans = (4^1) %MOD = 4
Constraints
1<=T<=100000
1<=N<=9*10^8
Note: Test cases have been updated and constraints are changed. Those who get TLE or WA are suggested to resubmit. GOOD LUCK there.

@wisfaq I mean with hard constraints we can get more elegant solution.

As this seems to easy we can create another version of this with higher constraints with n <=1e16 ~ 1e18 what other thinks. |
