Write a range Query function for a B-tree in pseudo code. (See Exercise 3 of Chapter 19 .) Assume that only the key values are needed (as opposed to the entire data record).
Chapter 19 Exercise 3:
Write a pseudo code function that performs a range query for a 2-3 tree. That is, the function should visit all items that are within a given range of values. For example, your function should visit all values between 100 and 1,000.
