Data Structures | Binary Search Trees | Question 12

Consider the same code as given in above question. What does the function print() do in general? The function print() receives root of a Binary Search Tree (BST) and a positive integer k as arguments.

// A BST node
struct node {
    int data;
    struct node *left, *right;
};

int count = 0;

void print(struct node *root, int k)
{
    if (root != NULL && count <= k)
    {
        print(root->right, k);
        count++;
        if (count == k)
          printf(\"%d \", root->data);
       print(root->left, k);
    }
}

(A)

Prints the kth smallest element in BST

(B)

Prints the kth largest element in BST

(C)

Prints the leftmost node at level k from root

(D)

Prints the rightmost node at level k from root
