Damages caused by and motivation behind DoS (Denial of Service) and DDoS (Distributed Denial of Service) attacks:
The damaged caused by DoS or DDoS attack is given below:
- Due to the problem in internet connection, the retailer may lose their sales.
- Revenue gained from advertisers with help of search engine goes slow down.
- The information is not delivered in timely manner.
- Frequent attacks take place such as dull reputations, greater sales loss, and so on.
- It may claim political anger to motivate the attacks over internet due to person who disagree the actions which is taken from specific company...

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.
