Technological obsolescence threat to
- It is a security threat and the reason is management’s drawback in planning and unsuccessful to foresee the technological advancements in the business.
- Technological obsolescence is experienced when the infrastructure becomes old and outdated, which leads to untrustworthy and unreliable systems, which may further lead to the loss data from attacks...

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.
