Set up a binary tree using the array method

Description: Create a binary tree using the array method

For example there is an array of int p[7] = {0, 1, 2, 3, 4, 5, 6}; So how do you build this array into a binary tree? Take a look at the following code.

/**************************************************************************** @file: main.cpp* @author: ugly_chen* @date: 2015.1.3* @remark: This code was for the binary tree with array* @note ************************************************* /#include <iostream>using namespace std;struct binary_tree_node{int data;binary_ tree_node* left_child;binary_tree_node* Right_child;}; void Create_tree (binary_tree_node* &tree, int a[], int len, int index) {if (index >= len) return;tree = new Binary_tr Ee_node;tree->data = A[index];tree->left_child = Null;tree->right_child = Null;create_tree (Tree->left_ Child, A, Len, 2 * index + 1); Create_tree (Tree->right_child, A, Len, 2 * index + 2);} void Print (binary_tree_node* p) {if (NULL = = p) return;cout << p->data; Print (P->left_child); Print (p->right_child);} int main () {int p[7] = {0, 1, 2, 3, 4, 5, 6};binary_tree_node*tree;create_tree (tree, p, 7, 0); Print (tree); return 0;}
