Binary Tree Sort Quiz Online Practice Test

1. Given the array 17, 8, 12, 4, 26, how many comparisons are required to build a Binary Search Tree (BST) from this array?

2. In binary tree sort, after constructing the BST, which traversal method is used to obtain the sorted sequence?

Inorder

Postorder

Preorder

Level order

3. What is the time complexity in the worst-case scenario for sorting with a binary tree?

O(n)

O(nlogn)

O(n2)

O(logn)

4. What is the time complexity of binary tree sort in the best-case scenario?

O(n)

O(nlogn)

O(n2)

O(logn)

5. Is binary tree sort classified as an in-place sorting algorithm?

True

False

Only in specific implementations

Depends on the tree structure

6. Which of the following statements is incorrect?

Binary tree sort and quick sort have the same running time

Binary tree sort uses a BST as its working structure

Binary tree sort becomes increasingly efficient as the number of elements grows

Both quick sort and binary tree sort are in-place sorting algorithms

7. Which sorting algorithm can be viewed as an enhancement over binary tree sort?

Heap sort

Quick sort

Selection sort

Insertion sort

8. Which of the following is accurate?

Statement I is true, but Statement II is false

Both Statement I and Statement II are false

Both Statement I and Statement II are true

Statement II is true, but Statement I is false

9. Consider the following insert() function for building a Binary Search Tree (BST) as part of the binary tree sort. Complete the missing condition in the function:

void insert(Tree* node, int newElement)
{
if (node == NULL)
{
node = createNewNode();
node->value = newElement;
node->left = NULL;
node->right = NULL;
return;
}
else if (__________________)
{
insert(node->left, newElement);
}
else
{
insert(node->right, newElement);
}
}

Which condition should replace the blank to ensure correct BST insertion?

newElement > node->value

newElement < node->value

newElement == node->value

newElement != node->value
