It should be twi dismantions. and it should dyanamically create GTAs and TAs processes based on the the number of the chpaters (you can assume that each chapter will always have two assingments).

The program should have a teacher process that reads the grades ("sample_in_grades.txt" grades file is available under the Assignment 1 section on Myls) of all assignments of all the chapters and creates a two dimensional matrix of grades
