Suppose that we have numbers between 1 and 100 in a binary search tree and want to search for the number 55. Which of the following sequences CANNOT be the sequence of nodes examined?
- a){10, 75, 64, 43, 60, 57, 55}
- b){90, 12, 68, 34, 62, 45, 55}
- c){9, 85, 47, 68, 43, 57, 55}
- d){79, 14, 72, 56, 16, 53, 55}
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Suppose that we have numbers between 1 and 100 in a binary search tree...
In BST on right side of parent number should be greater than it, but in C after 47, 43 appears that is wrong.

Suppose that we have numbers between 1 and 100 in a binary search tree...
Explanation:
To search for the number 55 in a binary search tree, we start at the root node and move down the tree, comparing the value at each node to 55. We can eliminate any sequence of nodes that does not follow the rules of a binary search tree, such as visiting a node with a value smaller than the current node when searching for a larger value.
Sequence that cannot be the sequence of nodes examined:
C) {9, 85, 47, 68, 43, 57, 55}
This sequence starts at the root node with a value of 9, which is smaller than the value we are searching for (55). The sequence then moves to a node with a value of 85, which is larger than the value we are searching for. This violates the rules of a binary search tree, where we should only move to the left subtree if the value is smaller than the current node and move to the right subtree if the value is larger.
The other sequences follow the rules of a binary search tree and could be valid sequences for searching for the number 55.
