gives the number of subtrees of tree.

Details

  • The number of subtrees of a Tree object is also the number of its nodes because each node is the root of a subtree of the original tree.
  • TreeSize[tree] is equivalent to TreeCount[tree,_].

TreeSize[tree] is equivalent to TreeCount[tree,_]:

TreeSize[Tree[{tree1,tree2,…}] gives 1+TreeSize[tree1]+TreeSize[tree2]+…:

TreeSize[Tree[data,None]] gives 1:

TreeSize[Tree[data,{}]] also gives 1:

TreeLeafCount[Tree[data,{}]] gives 0:
