- Suppose a biking environment consists of n ≥ 3 landmarks,which are linked by bike route in a cyclical manner. That is, thereis a bike route between landmark 1 and 2, between landmark 2 and 3,and so on until we link landmark n back to landmark 1. In the centerof these is a mountain which has a bike route to every single landmark.Besides these, there are no other bike routes in the biking environment.You can think of the landmarks and the single mountain as nodes, andthe bike routes as edges, which altogether form a graph G. A path is asequence of bike routes.What is the number of paths of length 2 in the graph in termsof n?What is the number of cycles of length 3 in the graph in termsof n?What is the number of cycles in the graph in terms of n?Each person in a group of n persons (n >= 4) has independent information known only to themselves. Whenever a person calls another person in the group, they exchange all the information they know at the time of calling. Design a sequence of calls (specifying the persons involved in each call) that they have to make in order to ensure that everyone knows all the information. How many calls are there in your scheme?. Draw the ERD for the following scenario. In a university, a Lecturer can teach many different courses and even the same course numerous times. Courses can also be taught by many lecturers. A student is enrolled in only one program but a program can contain many students. Students can be rolled in many courses at the same time and the courses have many students enrolled.
- Exercise 2: We have two lists of the same length representing sensors data. The second sensor is supposed to be redundant, so that the two lists should have identical values. But for practical reason there are going to be small differences. In order to evaluate the quality of data collected with our sensors, we want to calculate the total absolute values of differences between the values. For instance: Sensor 1 reading: Sensor 2 reading: 15, -4, 56, 10, -23 14, -9, 56, 14, -23 1, Differences: 5, 0, 4, The total absolute differences is 1+5+0+4+0 = 10 Write a python program that takes two lists of values and computes the total absolute values of differences between the valuesA dispatcher of RTOS has the following three resources, A, B, and C. A has 7 instances, B has 5 instances, and C has 6 instances. At this time, the allocation, request and available map is shown in table Q1 below. a. Is this system in a safe state? Execute necessary algorithm to show your result. b. Is there a valid sequence that can work for this map? If so show it and state if it is the only one or not. c. Given the allocation table below, if PO requests 1 more resource from A and it is granted, will the system be in a safe state? d. Given the allocation table below, if C has a total of 5 slots that will leave C with only 1 available instance, will the system be in a safe state? If not, suggest a solution to overcome deadlock.

I want a python code of a force directed graph of a user like CABI_Plantwise, where i can see the interactions with that accountLet us go back to the network we have been studying in the previous few homework assignments. Only, this time, it is a social network involving people who are connected by a friend relation- ship, represented below: as Prolog code on the left, and a graphical representation on the right. Note that this friend relationship is symmetric, since, on the left, for each pair X, Y of people, if friend(X,Y), then friend(Y,X), and in the graphical representation on the right, the “edges” do not have direction. friend(abi, bea). friend(abi, cory). friend(bea, cory). friend(bea, dina). friend(cory, dina). friend(dina, eva). friend(dina, fei). friend(eva, fei). friend(fei, gil). friend(bea, abi). friend(cory, abi). friend(cory, bea). friend(dina, bea). friend(dina, cory). friend(eva, dina). friend(fei, dina). friend(fei, eva). friend(gil, fei).

- Question 2: Suppose you have the following scenario: People who use the Palm Tree System are either farmers or experts. They both have name and phone number. The farmer has an address and has the ability to search and buy a product, reserve an appointment and add comments.
