I need a very detailed explanation of this problem. please l just dont want the code. every small detail matters. if possibe with diagrams too thanks

using C++

struct

class

A polynomial may be represented as a linked list where each node contains the coefficient and exponent of a term of the polynomial. The polynomial 4 X -3X2-5 would be represented as a linked list given below. Equation! 433 32 5 5 ohi Write a program system that reads two polynomials in any order of exponent from an input file, stores them as linked lists, adds them together, and prints the result as a polynomial to an output file. The result should be a third linked list. Hint: Travers both polynomials. If a particular exponent value is present in either of the two polynomials being summed, then it should be present in the answer. If it is present in both polynomials, then its coefficient is the sum of the corresponding coefficient in both polynomials. (If this sum is zero, the term should be deleted). NOTE: Must write a very general program using Object oriented concept. Do NOT use any library functions. All methods used in the program MUST be written in C++ and included in the program. KEYWORDS: Classes Pointers Submit a. Documented program b. Input file. c. Output file. ALL THREE DOCUEMNTS MUST BE STAPLED. Test run for the following inputs (Do not change the order of exponent in the input file) A) Equation1: Equation2: Result: 8X-7X+6X2 +6 8X - 7X2 + 6X4 +9X3-8 X+6X + 17XX -2 B) Equation1: Equation2: 8 -6 + 5x + 6X + 8X8 - 7X+6X 9X-6X2 + 5x + 18X-9
