To improve her mathematical knowledge, Bessie has been taking a graph theory course and finds herself stumped by the following problem. Please help her!

You are given a connected, undirected graph with vertices labeled $1\dots N$ and edges labeled $1\dots M$ ($2\le N\le 2\cdot 10^5$, $N-1\le M\le 4\cdot 10^5$). For each vertex $v$ in the graph, the following process is conducted: ​

1. Let $S=\{v\}$ and $h=0$.
2. While $|S|<N$, ​
   1. Out of all edges with exactly one endpoint in $S$, let $e$ be the edge with the minimum label.
   2. Add the endpoint of $e$ not in $S$ to $S$.
   3. Set $h=10h+e$.
   ​
3. Return $h\pmod{10^9+7}$.

Consider starting at $i=3$. First, we choose edge $2$, after which $S = \{3, 4\}$ and $h = 2$. Second, we choose edge $3$, after which $S = \{2, 3, 4\}$ and $h = 23$. Third, we choose edge $1$, after which $S = \{1, 2, 3, 4\}$ and $h = 231$. Finally, we choose edge $5$, after which $S = \{1, 2, 3, 4, 5\}$ and $h = 2315$. The answer for $i=3$ is therefore $2315$.
