Description
The depth of an ordered tree.
Map
binary search tree: left to right
Description
Return the shape of the binary search tree of the permutation as a non labelled binary tree.
Map
to ordered tree: right child = right brother
Description
Return an ordered tree of size n+1 by the following recursive rule:
  • if x is the right child of y, x becomes the right brother of y,
  • if x is the left child of y, x becomes the first child of y.
