Lele now is thinking about a simple function f(x). If x < 10 f(x) = x. If x >= 10 f(x) = a0 * f(x-1) + a1 * f(x-2) + a2 * f(x-3) + …… + a9 * f(x-10); And ai(0<=i<=9) can only be 0 or 1 . Now, I will give a0 ~ a9 and two positive integers k and m ,and could you help Lele to caculate f(k)%m.
Input
The problem contains mutiple test cases.Please process to the end of file.
In each case, there will be two lines. In the first line , there are two positive integers k and m. ( k<2*10^9 , m < 10^5 )In the second line , there are ten integers represent a0 ~ a9. OutputFor each case, output f(k) % m in one line.Sample Input10 99991 1 1 1 1 1 1 1 1 120 5001 0 1 0 1 0 1 0 1 0
Sample Output
