We perform the following steps: Recursively traverse the node’s left subtree in post-order; Recursively … Web9 Mar 2024 · For the pre-order, the root will be visited first after any recursion. With the in-order, the root always is visited after the left subtree and before the right subtree. For post-order traversal, the root is visited last in contrast with pre-order. Each one has its own perks and can be applied in many applications.
