Iterator for binary search tree

WebTo convert the above recursive procedure into an iterative one, we need an explicit stack. Following is a simple stack-based iterative algorithm to perform preorder traversal: iterativePreorder (node) if (node = null) return s —> empty stack s.push (node) while (not s.isEmpty ()) node —> s.pop () visit (node) if (node.right != null) WebWe know the binary search tree (BST) structure and the three ways to traverse it: inorder, preorder, and postorder. Now, let's create a class that takes a BST and can traverse it in …

WebBinary Search Trees Data Structures & File Management Mimicking Recursion What if we keep track of the node stack ourselves? – Add a Stack object as a field member of the iterator class. By severing the node history from the call stack, we are no longer “trapped” inside a sequence of recursive calls, so we can pause the traversal at will. Web19 okt. 2024 · The main point of iterator is that it should be "cheap" to make copies. All algorithms that use iterators pass them by value (and all the advice you see on these pages that we give is to pass iterators by value) as a result iterators are copied a lot and as a result need to be "cheap" to copy.
