Im Having problems trying to figure out this program i been doing this for a week now and cant seem to get the answer right

1 Description of the Program In this assignment, you are asked to do the following things 1. Read the courses from a file ("courses.txt"), and store them into a sorted linked list of courses 2. Remove all failed courses from the list 3. Add some retaken courses into the list; 4. Find the courses with " A" from the list; After completing each task, you should print the linked list. Your outputs should look like the following screenshot A sorted list of courses taken so far (imported from a file): -CPSC130 Computer_ProgrammingI3 -CPSC131 Computer_ProgramingII 3 -> CPSC141 Computer-organization 3 CPSC232 Assembler_Languages 3 -Math140 Calculus I -Math141 Calculus II A sorted list of courses after removing failed courses: -CPSC130 Computer_ProgrammingI 3 -CPSC131 Computer_ProgramingII 3 -CPSC232 Assembler_Languages 3 ->Math141 Calculus II A sorted list of courses after adding retaken courses
