Please help me with this problem:

What is the Big-O time complexity of verifying B-tree rule #5 for a tree with N key values? B-tree rule #5 states: For any non-leaf node: (1) An element at index i is greater than all the elements in subtree number i of the node, and (2) an element at index i is less than all the elements in subtree number of the node. Explain your answer by justifying the Big-O time of all of the main steps in the algorithm.
