Jun 6, 2013 · So, when you declare array like int tree [2^ (H+1)-1] it means that elements numbered from 0 to 2^ (H+1)-2 while you want them be numbered from 1 to 2^ (H+1)-1.

Oct 25, 2024 · Given a binary tree, the task is to find the size of the tree. The size of a tree is the number of nodes present in the tree. Examples: Input: Explanation: The number of nodes in the above binary tree is 6. Approach: The idea is to recursively calculate the size of tree.

Feb 13, 2023 · For the array representation of binary tree, we will form an array of size 2*n+1 size where n is the number of nodes the binary tree. Now we will move step by step for the array …

Oct 16, 2024 · Simple formulas can be derived for calculating the array index for each relative of a node R R from R R ’s index. No explicit pointers are necessary to reach a node’s left or right child.

Given a perfect binary tree, we store all nodes in an array according to the order of level-order traversal, where each node corresponds to a unique array index.

The size of the array TREE can be determined using the property of binary tree according to which a binary tree of height h can have atmost 2 h+1 -1 nodes.Therefore, the size of array tree is 2 h+1 -1. We can store the nodes of binary tree as follows: The root node A will be stored at index 1 i.e. at TREE [1].

The size of the array (tree) must be tracked. The size can be used to answer the question, "does some node have a left/right child?" To answer this question, the above formulas would be used to calculate the child index. If the index < array size, then the child exists! A node in a full tree will never have a right child without having a left ...
