(i) The height of the tree remains the same.
(ii) The node (disregarding the links) is present in the tree.
(iii) The root node remains unchanged (disregarding the links).
Which one of the following options is true?

Statements (ii) and (iii) are true
|
|
|
Statements (iii) and (i) are true
|
|
|
All the statements are false

Question 43 Explanation:
The B+ tree in previous question we get was,
Now after deleting 50 we get B+ tree as
Hence, correct statement is only (i) & (ii).
Now after deleting 50 we get B+ tree as
Hence, correct statement is only (i) & (ii).
