Given a binary search tree, print the elements in-order iteratively without using recursion.Note:Before you attempt this problem, you might want to try coding a pre-order traversal iterative solution first, because it is easier. On the other hand, coding a post-order iterative version is a ...
Brute force dump tree into array method It’s very similar to BST in order traversal. From that train of thought , we can easily have a brute force solution: perform an in-order traversal, dump that order into an array. Then we can have an pointer point to the array and move the poi...
Given two values k1 and k2 (where k1 < k2) and a root pointer to a Binary Search Tree. Find all the keys of tree in range k1 to k2. i.e. print all x such that k1<=x<=k2 and x is a key of given BST. Return all the keys in ascending order. 给定两个值 k1 和 k2(k1 <...
The simplest solution would be to check every element one by one and compare it with k (a so-called linear search). This approach works in O(n) , but doesn't utilize the fact that the array is sorted.Binary search of the value $7$ in an array. The image ...
Binary tree (a) has 8 nodes, with node 1 as its root. Node 1's left child is node 2; node 1's right child is node 3. Notice that a node doesn't need to have both a left child and right child. In binary tree (a), node 4, for example, has only a right child. Furthermor...
Figure 3. Example binary trees with their height computed at each node A BST exhibits log2nrunning times when its height, when defined in terms of the number of nodes,n, in the tree, is near the floor of log2n. (The floor of a numberxis the greatest integer less thanx. So, the ...

For example, we are guessing the number 8888, this is the process: >= 50 Yes >= 75 Yes >= 88 Yes >= 94 No >= 91 No >= 89 No ! 88 Part C— Basic binary search situations Task C1 You've got nn trees, the ii-th tree has the height of hihi meters. You are going to cut...

Given the tree: 4 / \ 2 7 / \ 1 3 And the value to search: 2 1. 2. 3. 4. 5. 6. 7. 8. You should return this subtree: 2 / \ 1 3 1. 2. 3. In the example above, if we want to search the value5, since there is no node with value5, we should returnNULL. ...
