Chapter 1, Problem R27RQ
Program Plan Intro
Botnet:
Botnet is the aggregation of internet accessing devices like Personal Computers (PC), servers, cellular components and many such. Every computer system in a botnet is considered as bot. These bots are formed together as a specific group which is managed by third parties to operate the spam data.
Distributed Denial of Service (DDoS) attack:
Distributed denial of service is a type of Denial of Service (DoS) attack that includes multiple computer systems which are affected by trojans. It increases the complexity in accessing the internet.

Construct an npda that accepts the language L = {a"b":n≥0,n‡m}.arrow_forwardYou are given a rope of length n meters and scissors that can cut the rope into any two pieces. 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.
