Question
The rules for deleting a key k from a node n:
 
Rule 1. If n has more than the number of keys and the k is not the largest in n, simply delete k from n.
Rule 2. If n has more than the minimum number of keys and the k is the largest in n, delete k and modify the higher level indexes to reflect the new largest key in n.
Rule 3. If n has exactly the minimum number of keys and one of the siblings of n has few enough keys, merge n with its sibling and delete a key from the parent node.
Rule 4. If n has exactly the minimum number of keys and one of the siblings of n has extra keys, redistribute by moving some keys from a sibling to n, and modify the higher level indexes to reflect the new largest keys in the affected nodes (if necessary).
