Problem D. Roman and Numbers

时间限制 4000 ms   内存限制 512 MB

Roman is a young mathematician, very famous in Uzhland. Unfortunately, Sereja doesn't think so. To make Sereja change his mind, Roman is ready to solve any mathematical problem. After some thought, Sereja asked Roma to find, how many numbers are close to number n, modulo m.

Number x is considered close to number n modulo m, if:

  • it can be obtained by rearranging the digits of number n,
  • it doesn't have any leading zeroes,
  • the remainder after dividing number x by m equals 0.

Roman is a good mathematician, but the number of such numbers is too huge for him. So he asks you to help him.
