Problem Statement

Let's define the cost of a simple undirected graph as the sum of the costs of its nodes. The cost of a node is defined
as D^K, where D is its degree.

You are given N and K. You need to find the sum of the costs of all possible simple undirected graphs with N nodes.
As this number may be very large, output the sum modulo 1005060097.
