... The depth (height) of the tree is the maximum depth of any node in the tree; in other words, it is the length of the longest path from the root to any node. A node with no children is called a leaf of the tree. All nonleaves are internal nodes. A forest is an acyclic graph (not necessarily connected ...

BINARY SEARCH TREE VISUALIZATION ALGORITHM
... From computational perspective this method is quite good, but it has a serious disadvantage. It uses a canvas in the least efficient way. If a tree is close to balanced6 or even complete7 this deficiency becomes less obvious. However, if a tree has its leaves distributed across all levels, the algor ...
