CERI2018E - A recurrence relation

Our task is to print some terms of the sequence defined by :

$u_0 = 0$ ;

$u_1 = 1$ ;

for $n\geqslant 0$, $u_{n+2} = 5u_{n+1}^2 - 3u_n$.

The first line of the input consist of a single integer number t which determines the number of tests.

In each of next t lines there is a single integer number n.

Print u_n modulo 1 000 000 007

Input:
3

10

Output:
5
122
