Problem Statement

How many integer sequences A1,A2,,ANA_1,A_2,\ldots,A_N of length NN satisfy all of the following conditions?

  • 0Ai90 \leq A_i \leq 9
  • There exists some ii such that Ai=0A_i=0 holds.
  • There exists some ii such that Ai=9A_i=9 holds.

The answer can be very large, so output it modulo 109+710^9 + 7.

Constraints

  • 1N1061 \leq N \leq 10^6
  • NN is an integer.

Input

Input is given from Standard Input in the following format:
