Grading FPRO

Write a Python program that, given the four components of the FPRO grade, 
by user input, returns the student's grade, an integer from 0 to 20, 
by using the formula:

grade = (LE + RE + 5 * PE + 3 * TE) / 50

The program returns:

 - "Input error", if the any of the components is not between 0 and 100
 - "RFC", if the PE < 40 or the TE < 40
 - the grade as an integer, otherwise
