  Problem description: 1. Below are classes for a project that involves the creation, displaying and evaluation of a polynomial in X. Organize the classes into a project and test the program. 2. Based on the project, create a project for the same purpose such that coefficients of polynomial may be numbers with decimal digits and that the literal coefficient in each term must be consistent with the other terms (i.e. A term can be added in an existing polynomial only if the literal is the same as the literal of the existing terms).
