Naive Approach: To solve the problem follow the below idea: A simple solution is to traverse the tree using (Inorder or Preorder or Postorder) and keep track of the closest smaller or same element. The idea of binary search is to use the information that the array is sorted and reduce the time complexity to O(Log n). Interval Tree: The idea is to augment a self-balancing Binary Search Tree (BST) like Red Black Tree, AVL Tree, etc to maintain set of The size of the Binary Indexed Tree is equal to the size of the input array, denoted as n. In the code below, we use a size of n+1 for ease of implementation. Construct the standard linked representation of given Binary Tree from this given representation. A perfect binary tree with n levels have 2 (n-1) nodes with all the leaf nodes at same level. In the above binary tree expected output is 2 but the function will give output as 3. This searching helps in optimizing the search technique with every iteration is referred to as binary search and readers do stress over Operations: BINARY TREE is unordered hence slower in process of insertion, deletion, and searching.

General operations performed using binary search: finding an element; lower_bound ; upper_bound; 1. binary_search: binary_search(start_ptr, end_ptr, num): This function returns true if the element is present in the container, else returns false. Since a full binary tree has 2^h 1 nodes, we can count the number of nodes in the binary tree and determine whether it is a power of 2 or not. Both the left and right subtrees must also be binary search trees. Binary Search Approach: Binary Search is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half.
