Properties of trees

Properties of trees

1. Number of nodes = Total degree + 1
   
2. Degree is m Trees and m The difference between fork trees
   
3. Degree is m The tree of i Layer up to have a m^(i - 1) Nodes （i>=1）;m Fork tree i Layer up to have a m^(i - 1) Nodes （i>=1）
   
4. The height is h Of m Fork trees have at most (m^h - 1) / (m - 1)
   
5. The height is h Of m Fork trees have at least h Nodes ; The height is h, Degree is m The trees of at least h+m-1 Nodes
