Space complexity:Amount of memory cells required in order to finish program or algorithm
Inplace: It is that doesn't requires extra space and produces output in memory that contains data however it contains small constant extra space.
A binary search tree includes n nodes and has an height h. Check all that applies...
Show that the tree height of a height-balanced binary search tree with n nodes is O(log n). (Hint: Let T(h) denote the fewest number of nodes that a height-balanced binary search tree of height h can have. Express T(h) in terms of T(h-1) and T(h-2). Then, find a lower bound of T(h) in terms of T(h-2). Finally, express the lower bound of T(h) in terms of h.)
Java : This function is to search through a binary tree left and right and return a count of the nodes above depth k. This is what I have so far, but I'm getting a Null pointer exception. public class MyIntSET { private Node root; private static class Node { public final int key; public Node left, right; public Node(int key) { this.key = key; } } public int sizeAboveDepth(int...
In regards to binary search tree, can you answer why a BST with N nodes has at least log2N levels and at most N levels. so the runtime complexity is best case 0(logN) and worst case 0(N). Can you explain this with the following numbers in this order? 7,1,64,28,77
Suppose a binary search tree has a preorder traversal of E B A D C H G F and an inorder traversal of A B C D E F G H. List all the leaf nodes of the binary tree, separated by a space. (Suppose the leaf nodes were A, B, and C. Then put A B C for your answer.)
A binary tree is a complete binary tree if all the internal nodes (including the root node) have exactly two child nodes and all the leaf nodes are at level 'h' corresponding to the height of the tree. Consider the code for the binary tree given to you for this question. Add code in the blank space provided for the member function checkCompleteBinaryTree( ) in the BinaryTree class. This member function should check whether the binary tree input by the...
Prove this Lemma. Lemma 2.2 A binary tree with height h has at most 2h+1-1 nodes. □
fill in the blank Binary Search Tree AVL Tree Red-Black Tree complexity O(log N), O(N) in the worst case O(log N) O(log N) Advantages - Increasing and decreasing order traversal is easy - Can be implemented - The complexity remains O(Log N) for a large number of input data. - Insertion and deletion operation is very efficient - The complexity remains O(Log N) for a large number of input data. Disadvantages - The complexity is O(N) in the worst case...
In general, assuming a balanced BST with n nodes (A balanced binary tree has roughly the same number of nodes in the left and right subtrees of the root), what is the maximum number of operations required to search for a key? Please notice that the tree in this exercise is not balanced. Trace the algorithm for creating a parse tree for the expression (((4 x 8)/6)–3 Please help me understand :(
(20 points) Suppose you are given a binary search tree T of n nodes (as discussed in class. each node v has v.left, v.right, and v.key). We assume that no two keys in T are equal. Given a value x, the rank operation rank() is to return the rank of x in T, which is defined to be one plus the number of keys of T smaller than 2. For example, if T has 3 keys smaller than r, then...
Java eclipse question. Given a binary search tree -------------M ---------G ---------N ------D----- H ---B----F How would you find the farthest from the root and most right side of the node? So, in this case, farthest nodes are B and F with height of 4 But the most right side of the node is F Therefore answer is F. I have //Will call helper method. public T findRightmostLowest(){ int lv = height();//This is the maxium height of the tree(4 in this...
