WebIn-order traversal is very commonly used on binary search trees because it returns values from the underlying set in order, according to the comparator that set up the binary search tree (hence the name). Post-order traversal while deleting or freeing nodes and values can delete or free an entire binary tree.

WebDec 28, 2010 · In-order, Pre-order, and Post-order traversals are Depth-First traversals. For a Graph, the complexity of a Depth First Traversal is O (n + m), where n is the number of nodes, and m is the number of edges. Since a Binary Tree is also a Graph, the same applies here. The complexity of each of these Depth-first traversals is O (n+m).
