IF YOU SEE THIS PLEASE HELP ME QUICK Think about real-world examples of problems whose solutions do—and do not—scale well. Additionally, think about a problem that is so complex that there is no computational solution to feasibly solve the problem in a reasonable amount of time.

Complete a short written response to the following question:

Identify two real-world examples of problems whose solutions do scale well.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
