Square Free Number
A Square free number is a number whose sum of every adjacent two digits is not a perfect square and dosen't contain digit 0. For example, 123 is a square free number cause sum of first two adjacent digits 1 + 2 = 3 is not a perfect square and sum of last two adjacent digits 2 + 3 = 5 is not a perfect square.
You are given an integer n. You have to calculate the number of n-digit square free number.
As the result can be very big, output the result modulo 1000000007 (1e9 + 7) ;
Input
First line of the input contains a number T, the number of testcase.
Each of the next T lines will contain an integer n .
Output
Output the number of square free numbers of length n .
Constraints:
T <= 1000.
1 <= n <= 1018 .
