Which technique is used for binary search Mcq?
Explanation: Using the divide and conquer master theorem.
What is the traversal strategy used in binary tree?
Explanation: The traversal technique used in a binary tree is breadth first traversal, also known as level order traversal.
Which is true for binary search Mcq?
This set of Data Structure Multiple Choice Questions & Answers (MCQs) focuses on “Binary Search Tree”. 1. Explanation: In order sequence of binary search trees will always give ascending order of elements. Remaining all are true regarding binary search trees.
Which of the following codes will check if a given binary tree is a full binary tree or not?
1) If a binary tree node is NULL then it is a full binary tree. 2) If a binary tree node does have empty left and right sub-trees, then it is a full binary tree by definition. 3) If a binary tree node has left and right sub-trees, then it is a part of a full binary tree by definition.
How do you check if a binary tree is BST?
Check if a Binary Tree is BST : Simple and Efficient Approach 1 The left subtree of a node contains only nodes with keys less than the node’s key. 2 The right subtree of a node contains only nodes with keys greater than the node’s key. 3 Both the left and right subtrees must also be binary search trees.
What is the difference between binary tree and binary search tree?
The binary tree is a tree where each node (except the leaves) has two children. Each node can have one parent and a maximum of two children. A binary search tree extends upon the concept of a binary tree. A binary search tree is set such that:- At the time of insertion of nodes, the decision about the position of the node is made.
How do binary search algorithms work?
In binary search we start with ‘n’ elements in search space and then if the mid element is not the element that we are looking for, we reduce the search space to ‘n/2’ and we go on reducing the search space till we either find the record that we are looking for or we get to only one element in search space and be done with this whole reduction.
What is the worst case time complexity of binary search?
Time Complexity: The worst-case time complexity of search and insert operations is O(h) where h is the height of the Binary Search Tree. In the worst case, we may have to travel from root to the deepest leaf node. The height of a skewed tree may become n and the time complexity of search and insert operation may become O(n).
