WebbNo recursion is necessary, because instead of relying on backtracking through a stack, a link back to the root of the (sub)tree is moved to the point at which it would be accessed in a recursive inorder tree traversal algorithm anyway — after its left subtree has finished. WebbHere we will discuss another way to traverse the tree data structure, i.e., inorder traversal. There are two approaches used for the inorder traversal: Inorder traversal using …
