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). WebAug 16, 2024 · Post-order traversal does the opposite of pre-order traversal, allowing us to explore leaves before roots. In-order Traversal In-order traversal is especially useful for flattening a tree into an array representation.
