G(n) is defined as

G(n) = G(n-1) + f(4n-1) , for n > 0

and G(0) = 0

f(i) is ith Fibonacci number. Given n you need to evaluate G(n) modulo 1000000007.

Input

First line contains number of test cases t (t < 40000). Each of the next t lines contain an integer n (0 <= n < 2^51).

Output

For each test case print G(n) modulo 1000000007.

Example

Input:
2
2
4

Output:
15
714

I was waiting for that moment since almost a year !!! It's feasible in Python !!! My code has 888 Bytes, do a small precomp part, then for each n compute flib(n) with only 6 mul(32+32=64bits) and 4 mod operations (and few other small ops). My IO are not magic, so it can be much faster.

-My first submission 8 months ago is using 5x5 matrix and got AC in 0.84s
-Now I try with 3x3 matrix and got AC again in 0.36s
-Then I try again with 2x2 matrix and AC again in 0.26s
-Next step, I reduce modulo operation and AC again in 0.16s
-After that, I use small precomputation and AC in 0.12s
-Finally fixing my fast I/O and submit again, AC in 0.11s
Nice problem, found so many trick for optimization.. and my best is 0.11s, I still curious how to get accepted in ~0.03s...

What is ans for 2^51-1 ?
-------------------------
EDIT: AC.
val for 2^51-1 is 847805763
Very tough to get AC in java

do not use unnecessary modulo it cost me 2 times TLE...

what's the problem here....even 2*2 matrix with log(n) solution is exceeding time limit........:(

Ahh... Done finally!! :)

'0' is not in the input file. My code which stops working if input = 0 , got AC.

bashrc is back: 2011-09-27 16:33:50

2*2 without any optimization....(even with redundancy) gave me AC
Time limit is fair...Just use pen and paper for expanding the series...

fun problem. enjoyed solving it

Can some one provide some big test cases with correct answers .

Thanks in advance.
