Code Binary Tree

Construct a full Binary Tree from an array

Constructing a full binary tree from an array means taking a collection of data elements (the array) and organizing them into a specific type of tree structure. A binary tree is a tree structure where each node has at most two child nodes, and a full binary tree is a binary tree where every node has either zero or two child nodes.

construct full binary tree using array

To construct a full binary tree from an array using the given hints, we can follow the following steps:

  1. Start with the root node, which is the first element in the array.

  2. To create the left subtree of a node, we need to find the index of the left child in the array. We can calculate this index by using the formula (location * 2) + 1, where location is the index of the current node. If the calculated index is less than the size of the array, we can create a new node as the left child of the current node, and repeat steps 2-4 for the left child.

  3. To create the right subtree of a node, we need to find the index of the right child in the array. We can calculate this index by using the formula (location * 2) + 2, where location is the index of the current node. If the calculated index is less than the size of the array, we can create a new node as the right child of the current node, and repeat steps 2-4 for the right child.

  4. If both the left and right subtrees have been created for a node, we can move on to the next node in the array and repeat steps 2-4.

  5. Once we have processed all nodes in the array, we will have constructed a full binary tree.
