A script stores information on potential subjects for an experiment in a vector of structures called subjects. The following shows an example of what the contents might be: > subjects (1) ans = name: 'Joey' sub_id: 111 height: 6.7000 weight: 222.2000 For this particular experiment, the only subjects who are eligible are those whose height or weight is lower than the average height or weight of all subjects. The script will print the names of those who are eligible. Create a vector with sample data in a script, and then write the code to accomplish this. Don't assume that the length of the vector is known; the code should be general.

Attention>>>>>>>>> project should written in C languages In the project, a student affairs information system simulation is requested to be made using structures (“struct”), linked lists (“linked list”) and files (“file”). According to this; a) Create a structure called a course. The members of this structure are code, name, instructor, term (can take Spring or Fall values), year, and a course pointer. Functions with prototype void insertCourse(CourseNodePtr* cr, CourseNodePtr* inscr, char* code), char* deleteCourse(CourseNodePtr* cr, CourseNodePtr* inscr, char* code) that will operate on course data structure elements, since the courses taken by the students are to be kept with a linked list. write. While writing the insertCourse() function, prevent the same student from taking the same course more than once. b) Create a structure called student. Let the members of this structure be id, name, surname, department, class (can take B.Sc., M.Sc., Ph.D.),…
Python question Analysis: Invariants (Q16-17) For each of the following functions, identify the loop invariant, exit condition and post condition. Question 16 (Invariant 1) This function returns the list of integers that are multiples of both 3 and 7 that occurs within a given list. Identify the loop exit condition, the loop post-condition, and the loop invariant at the end of the loop, which shows the algorithm’s correctness. def multiples_count(lst): """ Input: a list of integers, lst Output: the list of integers in lst that are multiples of both 3 and 7 """ res = [] for i in range(len(lst)): if lst[i]%3 == 0 and lst[i]%7 == 0: res.append(lst[i]) # Identify the loop invariant here return res Question 17 (Invariant 2) This function checks if a given list (of comparable elements) is sorted in ascending order. Identify the loop exit condition, the loop post-condition, and the loop invariant at the end of each iteration of the loop, which…

Q1: Assignment Difficulty Dan has a list of problems suitable for Assignment 4. The difficulties of these problems are stored in a list of integers a. The i-th problem’s difficulty is represented by a[i] (the higher the integer, the more difficult the problem). Dan is too busy eating saltines to worry about Assignment 4 decisions, so he asks Michael the TA to select at least two problems from the list for the assignment. Since there are many possible subsets of the problems to consider and Michael has a life, he decides to consider only sublists (definition follows) of the list of problems. To make grading the assignment easier, Michael wants to pick problems that don’t vary too much in difficulty. What is the smallest difference between the difficulties of the most difficult selected problem and the least difficult selected problem he can achieve by selecting a sublist of length at least 2 of the original list of problems? Definition: A sublist of a list a is any list you can obtain…
a) Write a program that asks user to enter number of vertices in an undirected graph and then the adjacency matrix representing the undirected graph. The program, then, must display whether the given graph is connected or not. You will find two sample runs of the program below. Sample 1 Sample 2 Enter number of vertices: 3 Enter number of vertices: 3 Enter adjacency matrix: 0 1 1 1 0 0 1 0 0 Enter adjacency matrix: 0 1 0 1 0 0 0 0 0 The graph is connected. The graph is not connected.
Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…
