An application programmer can prevent accessing an empty queue by using the isEmpty method in an if-statement to prevent such access

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

def ppv(tp, fp): # TODO 1 return   def TEST_ppv(): ppv_score = ppv(tp=100, fp=3) todo_check([ (np.isclose(ppv_score,0.9708, rtol=.01),"ppv_score is incorrect") ])   TEST_ppv() garbage_collect(['TEST_ppv'])

When you move the pointer too quickly, a phenomena known as submarineing happens when the cursor vanishes.

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 . The problem’s difficulty is represented by (the higher the integer, the more difficult the problem).ai-tha[i] 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 is any list you can obtain by…
