# C++ Program to Find Maximum Element in an Array using Binary Search

This is a C++ Program to find the maximum element of an array using Binary Search Tree. The time complexity of this program is O(log(n)).

## Algorithm

Begin
Construct the Binary Search Tree using the given data elements.
Next traverse the root pointer to the rightmost child node available.
Print the data part of the node as the maximum data element of the given data set.
Print the Depth of the maximum data.
End

## Example Code

#include<iostream>
using namespace std;
struct node {
int d;
node *left;
node *right;
};
node* CreateNode(int d) {
node *newnode = new node;
newnode->d = d;
newnode->left = NULL;
newnode->right = NULL;
return newnode;
}
node* InsertIntoTree(node* root, int d) {
node *temp = CreateNode(d);
node *t = new node;
t = root;
if(root == NULL)
root = temp;
else {
while(t != NULL){
if(t->d < d ) {
if(t->right == NULL) {
t->right = temp;
break;
}
t = t->right;
}
else if(t->d > d) {
if(t->left == NULL) {
t->left = temp;
break;
}
t = t->left;
}
}
}
return root;
}
int main() {
int n, i, a[10] = {86, 63, 95, 6, 7, 67, 52, 26, 45, 98};
node *root = new node;
root = NULL;
cout<<"\nData set:\n";
for(i = 0; i < 10; i++) {
cout<<a[i]<<" ";
root = InsertIntoTree(root, a[i]);
}
cout<<"\n\nThe maximum element of the given data set is\n ";
i = 0;
while(root->right != NULL) {
i++;
root = root->right;
}
cout<<root->d<<"\n"<<"data found at "<<i<<" depth from the root.";
return 0;
}

## Output

Data set:
86 63 95 6 7 67 52 26 45 98
The maximum element of the given data set is
98
data found at 2 depth from the root.
