The following B- tree has an order of 4 (see figure 1). Explain all the changes to the tree after 7 is inserted: • Why did the leaf node split into two nodes? • Why search-key 5 was added to the root node? • Assume search-key 4 was added instead of 5 by tuistake (see figure 2). When we perform searches on this tree, searching what value will return the wrong result? Explain why.
