Using Recursive Programming To solve a complex problem, we can first solve one step of the problem, and then the remaining steps can be represented as a similar but smaller problem We can use the same program to solve the smaller problem (recursive) Jeff Alic e Bob Eric E.g., Print_Manager_Recursive(‘Jeff’) will print out Jeff’s manager and higher level managers We just need to print out Jeff’s manager Alice, and Alice’s manager and higher level mangers. i.e., first print out Jeff’s manager by calling get_manager(‘jeff’) Then call Print_Manager_Recursive(‘Alice’)

Using Recursive Programming The recursion continues automatically Jeff Alic e Bob Eric Similarly, Print_manager_recursive(‘Alice’) will call Get_manager(‘Bob’) And Print_manager_recursive(‘Bob’) Next, Print_manager_recursive(‘Bob’) will call Get_manager(‘Eric’) and Print_manager_recursive(‘Eric’) What happen then?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
