Explanation of Solution
Describe the method of phishing:
Phishing is a process of using fake email to try to have access or steal user’s personal information without having the permission of the user.
- The sensitive information that is usually phished is usually credit card details, user passwords, bank account information.
- Users commonly using electrical communication media are prone to this type of attack.
- For example:
A user receives a generic mail about a transaction that was cancelled in a reputed branch where the user has his or her accounts.
In order to secure the account a link is attached to verify that the transaction was made by the user...

- 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 <= narrow_forwardTrace 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.
