Expert Solution & Answer
Chapter 1, Problem 4E
Explanation of Solution
Phreaker’s Manual:
- This phenomenon first came into focus in late 1950s where the phreaks could easily switch the calls from phone handset; this allows making free calls around the world.
- In initial days, this term was used to refer the group of people who had reversed engineered the system of tones that are used to route long-distance calls.
- By 1980s, this method was stated as similar to that of computer hacking. Thus was sometimes referred as H/P culture (H stands for hacking and P stands for phreaking).
- Phone phreaking is also defined as a mischievous act that includes many illegal methods in order to avoid paying for a telecommunication invoice, order, transfer, or any other service...

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. What is the benefit of using dynamic programming for this problem? What are the key principles of dynamic programming used in your algorithm?arrow_forward
