Binary Search Trees MCQ - 2
Consider we have a binary tree T. We now want to check if a binary tree S is a subtree of T. To do this, first, try to check if you find a node in T that is also in S. Once you find this common node, check if the following nodes are also a part of S. If yes, we can safely say that S is a subtree of T. Consider two nodes n1 and n2 that are part of a binary tree. The distance between n1 and n2 is equal to the minimum number of edges that need to be traversed to reach from one node to the other. It is important to note that you traverse the shortest distance between the nodes. A binary search tree BST is a special type of binary tree in which each internal node contains a key. Thus, if n1 is a node that has a key 8, then every node in the left subtree of n1 will contain keys lesser than 8, and every node in the right subtree of n1 will contain keys greater than 8.

Self-balanced binary search trees automatically keep their height as small as possible when operations like insertion and deletion take place. For a BST to be self-balanced, it is important that it consistently follows the rules of BST so that the left subtree has lower-valued keys while the right subtree has high valued keys. An AVL tree is a self-balancing binary tree that checks the height of its left subtree and right subtree and assures that the difference is not more than 1.
Data Structure Questions and Answers-Binary Search Tree
Workspace Answer: a Explanation: The answer is a. The binary tree contains three traversal techniques, preorder, postorder and inorder traversal. The value of the left child should be less than the root node The value of the right child should be greater than the root node. The left and right sub trees should also be a binary search tree None of the above Workspace Answer: d Explanation: The answer is d. All the three options, i. In binary search tree, the left child should be less than the root node and the right child should be greater than the value of the root node. A tree which is binary search tree and height balanced tree. A tree which is a binary search tree but unbalanced tree. An AVL tree is a binary search tree and height balanced tree. AVL tree needs more space to store the balance factor. Both b and c Workspace Answer: d Explanation: The answer is d. Red Black tree requires fewer rotations for inserting or deleting the node whereas AVL tree requires multiple rotations to balance the tree.

Discuss it Question 2 Explanation: Let X be the node to be deleted in a tree with root as 'root'. There are three cases for deletion 1 X is a leaf node: We change left or right pointer of parent to NULL depending upon whether X is left or right child of its parent and we delete X 2 One child of X is empty: We copy values of non-empty child to X and delete the non-empty child 3 Both children of X are non-empty: In this case, we find inorder successor of X. Let the inorder successor be Y. We copy the contents of Y to X, and delete Y. Sp we need inorder successor only when both left and right child of X are not empty. In this case, the inorder successor Y can never be an ancestor of X. In this case, the inorder successor is the leftmost node in right subtree of X. Since it is leftmost node, the left child of Y must be empty. Question 3 We are given a set of n distinct elements and an unlabeled binary tree with n nodes.

TRUE When using "binary search" to search an array, the array must always be sorted in increasing order. FALSE When using "binary search" to search an array, and the arrays is not sorted, then: he program will crash FALSE you will never find the value you are looking for even if it does exist in the array FALSE sometimes the search will be successful, but sometimes it will fail even if the value does exist in the array TRUE Suppose A is an array containing numbers in increasing order, but some numbers occur more than once.
Data Structure MCQ Questions Answer – Computer Engineering CSE
When using a binary search for a value, the binary search always finds the first occurance of a value FALSE the binary search always finds the last occurance of a value FALSE sometimes it finds the first, sometimes the last, and sometimes a value in between. TRUE When you insert the values 40, 30, 60, 40, and 50 into a binary search tree, and then search for, say, 40, the search will find the second occurance of 40, not the first. FALSE Suppose you insert the values 40, 30, 60, 50, and 10 into a binary search tree, and then use the following function: then the output of calling someOrder root would be: 10, 30, 40, 50, then As we have discussed this class, it used single recursion FALSE double recursion TRUE A recursive function is a function that calls itself TRUE If a recursive function does not have a base case it is likely to result in an infinite loop TRUE If a recursive function does have a base case, it will never result in a recursive loop FALSE A double-recursive function is a function that calls itself again, but doubles the input argument when calling itself.

In this tutorial, I will help you understand binary search better by going through some basic problems then applying them in technical questions asked during interviews. Beyond arrays: the discrete binary search Problem: Finding a value in a sorted sequence A sequence or array is really just a function which associates integers that is indices of array with the corresponding values in an array. However, there is no reason to restrict our usage of binary search to just sequences.
Implementing a Binary Search Tree in JavaScript
In fact, we can use the same binary search algorithm on any monotonic function whose domain is the set of integers. The only difference is, we will use function evaluation instead of array lookups. We will find x for which f x is equal to some target value. When working with arrays, time complexity is O log n. But in this problem, it may change because we need to evaluate the function f x at every step although we will be free of any memory constraints that were present while working with arrays. Which problem can be solved using Binary search? If we talk in a less mathematical way, try to break the problem in a yes or no question. If the problem follows the structure below, then binary search can be used don't worry if you don't get it clearly, example problems will make it clearer.

As a consequence, if you were to ask the question for each element in the search space in order , you would get a series of no answers followed by a series of yes answers. It can be easily observed that Yes and No can swap places in the description above, which means we will have a series of yeses followed by nos. In this case, yes for any x will mean that we will get yes for all elements before x and no for any x will mean that we will get no for all elements after x. Example problems Still confusing?

Let's discuss some problems which will make the method clearer. Test your understanding of binary search by clicking the link to the problem, then once you're done answering, click the solution to the code. The explanation for each solution is provided in this tutorial. Explanation: For the problem at hand, let us define a function F x such that. Thus, the problem satisfies the monotonicity condition necessary for binary search. Since we have at least two cows, the best we can do is to push them towards the stalls at the end—so there is no way we can achieve this better. We can do this with a greedy algorithm : Keep placing cows at the leftmost possible stalls such that they are at least x distance away from the last cow placed. For writing the IsPossible x function, we can just start allocating painters to Boards such that it's taken one painter x time, at most, to paint.

If the number of allocated painters is not more than the available, then it is possible to paint the boards in x time else it is not. We use binary search over the answer with limits 0, maximum time it can take , then we find if isPossible x. If it is possible, then we search for the answer in the left half, else we go to the right half. Related tutorials you might be interested in.

Data structure refers to the way data is organized and manipulated. It seeks to find ways to make data access more efficient. When dealing with data structure, we not only focus on one piece of data, but rather different set of data and how they can relate to one another in an organized manner. Basically, the key difference is the memory area that is being accessed.
Binary Search
When dealing with the structure xearch resides the main memory of the computer system, this is referred to as storage structure. When vinary with an auxiliary structure, we refer to it as file structure. A binary search is an algorithm that is best applied quedtions search a list when the elements are adn in order or sorted. The list is search starting in the middle, such that if that middle value is not the target search key, it will check to see if it will continue the search on the lower half of the list or the higher half.

The split and search will then continue in the same manner. A linked list is binary search tree exam questions and answers sequence of nodes bihary which each node is connected to the node following it. This forms a chain-like link of data storage. Data Structures Interview Questions and Answers How do you reference all the elements in questkons one-dimension array? To do this, an indexed loop is used, such that the counter runs from 0 to the array size minus one. In this manner, we are able to reference all the elements in sequence by using the loop counter as the array subscript. Data structure is important in almost every aspect where data is involved. In general, algorithms that involve efficient data structure is applied exak the following areas: numerical analysis, operating system, A. Using this scheme, data that was stored last, should be the one to be extracted first.

This also means that in order to gain access to the first data, all the other data that was stored before this first data must first be retrieved and extracted. A queue is a data structure that can simulates a list or stream of data. In this structure, new elements are inserted at one end and existing elements are removed from the rtee end. A binary tree is one type of data structure that has two nodes, a left node and a right node. In programming, binary trees are actually an extension of the linked list structures. Data Structures Interview Questions and Answers Bihary data structure is applied when dealing with a recursive function? Recursion, which is basically a function that amd itself based on a terminating condition, makes use of the stack. Using LIFO, a call to a recursive function saves the return address so that it knows how to return to the calling function after the call terminates.
