The level order traversal will traverse the above tree in ... Space Complexity of Iterative Inorder Traversal of a Binary Tree The space complexity is O(N). Considering the worst case, where the tree can be a skewed one, space complexity will be equal to the number of nodes in the binary tree. Apache drill bitandspecft100x75Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys Let's ask what's the best-case and worst-case scenarios for the successor function are when we have an inorder traversal of a binary search tree: Remember that in inorder traversal, the left subtree is visited, then the parent node, then the right subtree. As each node of the binary tree is visited at least once, time complexity O(n) along with space complexity of O(2 (l-1)) where l is the number of levels in the binary tree. The method explained above has an additional space complexity, is there a way to avoid that? Binary search Growth of functions Linked lists For any of the above algorithms must be able to: write code give time and space complexity (inlcuding the code you write) sorting and binary search - be able to show the data after each iteration of the [outter/inner] loop without seeing the code. Binary search tree property For every node X, all the keys in its left subtree are smaller than the key value in X, and all the keys in its right subtree are larger than the key value in X Binary Search Trees A binary search tree Not a binary search tree Binary search trees Average depth of a node is O(log N); maximum depth of a node is O(N ... //Description: Binary Search Tree with array implementation, it has inorder, postorder and pre order traversals. //Note: it is not advisable to use array in binary search tree because it consumes a lot of memory in the long run // instead use linked list this is just a reference to understand more about BST. Cute aesthetic text symbolsAn algorithm A is of polynomial complexity is there exist a polynomial p( ) such that the computing time of A is O(p(n)). Definition: P is a set of all decision problems solvable by a deterministic algorithm in polynomial time. NP is the set of all decision problems solvable by a nondeterministic algorithm in polynomial time. P NP An AVL tree is still a binary search tree. So, if you want to visit every node, that's O(n) (it's true of any binary search tree). Now, if you were to do a search/find operation on each value of the tree (rather than use recursion from the root), then, it would be O(n lg n).
