A firmware engineer has written a single monolithic script of over 2000 lines of code to control an autonomous survey drone. To improve the code, they decide to refactor it by dividing the code into structured subprograms (functions and procedures) for individual tasks, such as read_gps(), calculate_bearing(), and adjust_thrusters().
Explain two distinct benefits that restructuring the program into subprograms provides for the development and maintenance of this drone system.
