题目描述

Amr doesn't like Maths as he finds it really boring, so he usually sleeps in Maths lectures. But one day the teacher suspected that Amr is sleeping and asked him a question to make sure he wasn't.

First he gave Amr two positive integers nn and kk . Then he asked Amr, how many integer numbers x>0 exist such that:

  • Decimal representation of xx (without leading zeroes) consists of exactly nn digits;
  • There exists some integer y>0 such that:
    • ;
    • decimal representation of yy is a suffix of decimal representation of xx .

As the answer to this question may be pretty huge the teacher asked Amr to output only its remainder modulo a number mm .

Can you help Amr escape this embarrassing situation?
