How many cases are considered for deleting a node from a binary search tree?
There are three primary cases to consider when deleting a node from a binary search tree (BST): Leaf Node: If the node is a leaf (has no children), it can simply be removed. Single Child: If the node has one child, it can be removed, and its child can take its place. Two Children: If the node has two children, it is typically replaced with its in-order predecessor (maximum value in the left subtree) or in-order successor (minimum value in the right subtree), followed by deleting the predecessor or successor node.
How insertion sort is best by binary search?
Insertion sort can be optimized using binary search to find the appropriate position for each element being inserted into the sorted portion of the array. While traditional insertion sort has a linear search time of O(n) for finding the insertion point, using binary search reduces this to O(log n). This hybrid approach maintains the overall O(n^2) time complexity of insertion sort but improves the efficiency of locating the insertion index, making it faster in practice for larger datasets. However, the overall performance gain is more noticeable in smaller datasets where the overhead of binary search is minimal.
What assumption about the list is made when binary search is conducted?
Binary search requires that the list be in search key order.
What is the difference between extended binary tree and a binary search tree?
A strictly binary tree is one where every node other than the leaves has exactly 2 child nodes. Such trees are also known as 2-trees or full binary trees. An extended binary tree is a tree that has been transformed into a full binary tree. This transformation is achieved by inserting special "external" nodes such that every "internal" node has exactly two children.
A binary search of an orderd set of elements in an array or a sequential search of the elements.Which one is faster?
A binary search is much faster.
What is binary search in data structure using c?
a tree which has atmost two nodes is called binary tree binary search tree is a binary tree which satisfies the following 1.every node in tree must be distinct 2.values in right subtree > value at root 3.values in left subtree < value at root 4.left,right subtrees must be binary search trees

What are the differences between a heap and a binary search tree in terms of their structure and operations?
A heap is a complete binary tree where each node has a value greater than or equal to its children, and it is typically used for priority queue operations like inserting and removing the maximum element. On the other hand, a binary search tree is a binary tree where each node has a value greater than all nodes in its left subtree and less than all nodes in its right subtree, and it is used for efficient searching, insertion, and deletion operations.

What is a multiway serach tree?
Multiway search tree of degree n. A generalization of a binary search tree to a tree of degree n where each node in the ordered tree has m ← n children and contains (m-1) ordered key values, called subkeys. For some given search key, if the key is less than the first subkey then the first subtree (if it exists) is searched for the key; if the key lies between the i th and (i + 1)th subkey, wherei = 1,2,…, m-2then the (i + 1)th subtree (if it exists) is searched; if the key is greater than the last subkey then the m th subtree (if it exists) is searched.
What is the difference between avl tree and binary tree?
A binary tree is a tree data structure in which each node has at most two children. Typically the child nodes are called left and right. One common use of binary trees is binary search trees; another is binary heaps. A binary search tree (BST) is a binary tree data structure which has the following properties: ->each node has a value; ->a total order is defined on these values; ->the left subtree of a node contains only values less than the node's value; ->the right subtree of a node contains only values greater than or equal to the node's value. An AVL tree is a self-balancing binary search tree. In an AVL tree the heights of the two child subtrees of any node differ by at most one, therefore it is also called height-balanced. Lookup, insertion, and deletion all take O(log n) time in both the average and worst cases. Additions and deletions may require the tree to be rebalanced by one or more tree rotations.

What are the key differences between a binary search tree and a heap data structure?
A binary search tree is a data structure where each node has at most two children, and the left child is smaller than the parent while the right child is larger. It is used for efficient searching, insertion, and deletion of elements. A heap is a complete binary tree where each node is greater than or equal to its children (max heap) or less than or equal to its children (min heap). It is used for priority queue operations like finding the maximum or minimum element quickly. The key differences between a binary search tree and a heap are: Binary search trees maintain a specific order of elements based on their values, while heaps maintain a specific hierarchical structure based on the relationship between parent and child nodes. Binary search trees are used for efficient searching and sorting operations, while heaps are used for priority queue operations. In a binary search tree, the left child is smaller than the parent and the right child is larger, while in a heap, the parent is greater than or equal to its children (max heap) or less than or equal to its children (min heap).
What assumption about the list is made when binary search is conducted?
Binary search requires that the list be in search key order.
How can you merge two binary search trees into a single binary search tree?
To merge two binary search trees into a single binary search tree, you can perform an in-order traversal on each tree to extract their elements, combine the elements into a single sorted list, and then construct a new binary search tree from the sorted list. This process ensures that the resulting tree maintains the binary search tree property.

An extended binary tree is a tree that has been transformed into a full binary tree. This transformation is achieved by inserting special "external" nodes such that every "internal" node has exactly two children.
What is the use of binary?
Binary trees are commonly used to implement binary search tree and binary heaps.
