题目描述

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 nn , modulo mm .

Number xx is considered close to number nn modulo mm , if:

  • it can be obtained by rearranging the digits of number nn ,
  • it doesn't have any leading zeroes,
  • the remainder after dividing number xx by mm 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.

输入格式

The first line contains two integers: nn (1<=n<10^{18}) and mm (1<=m<=100)(1<=m<=100) .

输出格式

In a single line print a single integer — the number of numbers close to number nn modulo mm .
