Inorder traversal visits nodes in this order: left child, current node, then right child. It is often used to get nodes in ascending order for binary search trees.
Preorder traversal visits nodes in this order: current node first, then left child, then right child. It is useful for copying trees or getting prefix expressions.
Postorder traversal visits nodes in this order: left child, right child, then current node. It is often used to delete trees or evaluate postfix expressions.
Because inorder traversal visits nodes in ascending order, it helps retrieve sorted data from a binary search tree.
Preorder traversal is best for copying a tree because it visits the root node before its children, preserving the structure.
Preorder traversal visits the root node first, then left and right children.
Inorder traversal visits nodes in ascending order in a binary search tree.
Postorder traversal visits the root node last, after its children.
Postorder traversal visits children before the parent, making it safe to delete nodes.
Preorder traversal prints the root node before its children.
