Question
Five node splitting operations occur when an entry is inserted into a B-tree. Then how many nodes are written?
Solution
When an entry is inserted into a B-tree and a node splitting operation occurs, two nodes are written: the original node that is being split and the new node that is created from the split.
So, if five node splitting operations occur, that means 5 original nodes are split and 5 new nodes are created.
Therefore, a total of 5 (original nodes) + 5 (new nodes) = 10 nodes are written.
