Consider the following code snippet:
#include <iostream>
using namespace std;
struct Node {
    int data;
    Node* left;
    Node* right;
};
int main() {
    Node* root = new Node;
    root->data = 10;
    root->left = new Node;
    root->left->data = 20;
    root->left->left = NULL;
    root->left->right = NULL;
    root->right = new Node;
    root->right->data = 30;
    root->right->left = NULL;
    root->right->right = NULL;
    cout << root->left->data << endl;
    return 0;
}
What will be the output of the above code?
  • a)
    10
  • b)
    20
  • c)
    30
  • d)
    None of the above
Correct answer is option 'B'. Can you explain this answer?
