WebApr 20, 2024 · Preorder traversal is a type of depth-first search (DFS) approach, and DFS problems are generally best solved with a recursive function. In this case, we can even make the main function its own recursive function, rather than having to define a separate recursive helper. WebPreorder traversal is a depth first algorithm. We first print the value of the node,them move to the left subtree and finally to the right subtree. If we need to explore more about the node itself before inspecting its leaves, we use preorder traversal. Preorder traversal is used to find the prefix expression of an expression tree. tax attorneys mobile al
