How do I traverse a tree without using recursion?

Below is an algorithm for traversing binary tree using stack. See this for step wise step execution of the algorithm. 1) Create an empty stack S. 2) Initialize current node as root 3) Push the current node to S and set current = current->left until current is NULL 4) If current is NULL and stack is not empty then a) Pop the top item from stack. WebThe time complexity of postorder traversal is O(n), where 'n' is the size of binary tree. Whereas, the space complexity of postorder traversal is O(1), if we do not consider the stack size for function calls. Otherwise, the space complexity of postorder traversal is O(h), where 'h' is the height of tree. Implementation of Postorder traversal philippines shortageWebYour task is to complete the function inOrder () which takes the root of the tree as input and returns a list containing the inorder traversal of the tree, calculated without using recursion.

WebA threaded binary tree is an adapted representation of binary trees where some nil-pointers are used to link to successor nodes in the tree. This extra information can be … WebApr 8, 2024 · Successful recursion requires branching at some point, a division of the code path into at least two cases, one of them the base case. Whether or not a return statement is required follows the same rule as that for non-recursive functions – a function that returns void is not required to have an explicit return statement.
