Map
runsort
Description
The permutation obtained by sorting the increasing runs lexicographically.
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
right rotate
Description
Return the result of right rotation applied to a binary tree.
Right rotation on binary trees is defined as follows: Let T be a binary tree such that the left child of the root of T is a node. Let C be the right child of the root of T, and let A and B be the left and right children of the left child of the root of T. (Keep in mind that nodes of trees are identified with the subtrees consisting of their descendants.) Then, the right rotation of T is the binary tree in which the left child of the root is A, whereas the right child of the root is a node whose left and right children are B and C.
