Consider the following B+ tree (no duplicates). Start with the original tree index for each question part. Apply the action(s) asked and SHOW the resulting tree. In the case of a split, "push right" the extra value (3 values split1 into 1 and 2, with the 2 values placed in the right node). Node P1 is the root of the tree.

 

insert 42* into the tree, how many reads are done and on which pages, how many writes are done and on which pages and why?

2. insert 47*, 43*, how many reads are done and on which pages, how many writes are done and on which pages and why?
