Expert Solution & Answer
Chapter 8, Problem 13CSQ
Explanation of Solution
Security and control weaknesses:
- Equifax reported on 7th September 2017 an unprecedent breach to its security by hackers, that resulted in loss of large amount of sensitive and personal data of its customers.
- Report states that for the period between mid-May to July 2017, information of 143 million customers were gained access by the hackers including 209,000 credit card details, personal information related to disputes, social security number and driver’s license numbers.
- This personal data can be misused in a lot of fraudulent ways as the hackers have access to private information of bank accounts, medical histories and financing.
- This enormous privacy disruption was reported by Equifax to local enforcement and also as necessary action, a
cybersecurity firm was hired to investigate on the cause...

Just wanted to know, if you had a scene graph, how do you get multiple components from a specific scene node within a scene graph? Like if I wanted to get a component from wheel from the scene graph, does that require traversing still?
Like if a physics component requires a transform component and these two component are part of the same scene node. How does the physics component knows how to get the scene object's transform it is attached to, this being in a scene graph?
How to develop a C program that receives the message sent by the provided program and displays the name and email included in the message on the screen?Here is the code of the program that sends the message for reference:

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
