Code and Output:
#include <iostream>
using namespace std;
struct Node {
   int data;
   Node* left;
   Node* right;
};
Node* insert(Node* root, int key) {
   if (root == NULL) {
      Node* newNode = new Node();
      newNode->data = key;
      newNode->left = NULL;
      newNode->right = NULL;
      return newNode;
   }
   if (key < root->data)
      root->left = insert(root->left, key);
   else if (key > root->data)
      root->right = insert(root->right, key);
   return root;
}
int main() {
   Node* root = NULL;
   root = insert(root, 10);
   root = insert(root, 20);
   root = insert(root, 5);
   root = insert(root, 15);
   cout << root->left->right->data << endl;
   return 0;
}
What will be the output of the above code?
  • a)
    10
  • b)
    20
  • c)
    5
  • d)
    15
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Code and Output:#include <iostream>using namespace std;struct No...
The code inserts nodes with values 10, 20, 5, and 15 into a binary search tree. The statement "cout << root->left->right->data << endl;" prints the value of the right child of the left child of the root, which is 20.
