WebJul 30, 2024 · In the earlier article on preorder traversal, we saw that preorder traversal is one of traversal which is based on depth-first search traversal. The basic concept for preorder traversal lies behind its name. "pre" means first/before and that's why the root is traversed before its left & right subtree. The basic rule is: First, traverse the root WebAug 23, 2024 · The initial call to the traversal function passes in a pointer to the root node of the tree. The traversal function visits rt and its children (if any) in the desired order. For example, a preorder traversal specifies that rt be visited before its children. This can easily be implemented as follows. Java Java (Generic) Toggle Tree View
