Question
Chapter 14, Problem 40E
Program Plan Intro
Meteorological model:
- Meteorological models are used to predict the weather report.
- This weather prediction is a continuous simulation because there is a continuous change in the weather. So the changes are to be updated periodically.
- Meteorological models use set of differential equations, which measure the rate of changes in weather.
- Computing equations in meteorological models are much costlier

What is the number of derangements of size k from the set {1,2,...n} to the set {1,2,...n} so that f(x) != x exactly k times with 1 <= k <= n
Trace a State Space Tree introduced in the Chapter 5.1 using algorithms depth_first_search (page 205), checknode (page 207), and expand (page 210).
Assume that State Space Tree is a two-level full binary tree (root is level 0). Node #2 (according to notation used in the Figure 5.1, page 204) is non-promising.
Count the number of steps performed by each of those three algorithms. Consider execution of instructions like "visit node" or execution of "promising function" as one step, "write a solution" as an exit call.
Note: no need to print or a draw a whole tree. Just provide three numbers as an answer
