Problem

You are given an integer P.

Also, you are given Q queries of the following type:

  • N: Determine the count of distinct arrays of size N and 1 such that:
    • Each array element is a prime number
    • Product of the value of all the array elements is P
    • Array formed is palindromic

Note

  • Two arrays are said to be distinct if there exists at least one index where the value of element present in both the arrays is different.
  • An array is said to be palindromic if it reads same from the left to right and right to left direction.
  • Since the count can be very large, print the output in modulo 109+7.
  • Assume 1 based indexing.

Input format

  • The first line contains an integer P.
  • The second line contains an integer Q.
  • The next line contains Q space-separated integers that denotes the value of N for each query.

Output format

Print Q space-separated integers denoting the result for Q queries.
