Thread: I need some ideas on this problem

Here is the problem: 3.11 Write a function to add two polynomials. Do not destroy the input. Use a linked list implementation. If
the polynomials have M and N terms, respertively, what is the time complexity of your program?

Can anyone give me some insight on how to do this? How could you write this function? I am not looking for code but maybe a explanation of how the code would look like.
