1. Tree structure: a tree is a finite set T of n (n > = 0) nodes. When n=0, it is called an empty tree; When n > 0, the set satisfies the following conditions: (1) there must be a specific node called root, which has no direct precursor but 0 or more direct successors. (2) the remaining n-1 nodes can be divided into m (M > = 0) disjoin ...
