Expert Solution & Answer
Chapter 8, Problem 1SG
Explanation of Solution
Secondary storage:
The secondary storage is also referred as storage medium and its plural form is storage media; it is a physical device that saves data, information, codes, and applications to a computer.
- It is used to place, save, and recover the electronic data.
- It stores the non-critical data, which does not require frequent access.
- Data can be accessed with less frequency that can be migrated with secondary storage devices to free up the space and enhance the primary storage device performance and reduce the cost for overall storage.
Types of storage media:
The types of storage media are given below:
- Hard disk.
- Memory cards.
- Magnetic strip cards.
- Smart cards.
- USB flash drives.
- Optical discs and so on.
Another advanced secondary storage option is “cloud storage”; it is used to save data on servers in internet because the user can access the files on cloud storage through search engine and the files that are stored in actual media are translucent to the user.

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.
