How will you create a binary search tree using linked list?
Algorithm
- Define Node class which has three attributes namely: data left and right.
- When a node is created, data will pass to data attribute of the node and both left and right will be set to null.
- Define another class which has an attribute root.
- insert() will add a new node to the tree:
Can sorted data be added to a binary tree?
A sorted linked list is used to construct a binary tree from the leaves to the root. The idea is to insert nodes in a binary tree in the same order as they appear in the linked list so that the tree can be constructed with the time complexity of O ( n ) O(n) O(n).
Can you binary sort a linked list?
Yes, Binary search is possible on the linked list if the list is ordered and you know the count of elements in list. But While sorting the list, you can access a single element at a time through a pointer to that node i.e. either a previous node or next node.
How to convert sorted list to binary search tree?
Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. A height balanced BST : a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1.
How to sorted linked list to balanced BST?
1) Get the Middle of the linked list and make it root. 2) Recursively do same for the left half and right half. a) Get the middle of the left half and make it left child of the root created in step 1. b) Get the middle of right half and make it the right child of the root created in step 1.
How to create a balanced binary search tree?
A balanced binary tree is a tree whose height is , where is the number of nodes inside the tree. For each node inside the balanced tree, the height of the left subtree mustn’t differ by more than one from the height of the right subtree.
How to create nodes from a linked list?
Two traversal of the linked list is all we need. First traversal to get the length of the list (which is then passed in as the parameter n into the function), then create nodes by the list’s order.
