Input: 2 polynomials from severl variables in mathematical form (some signs of opertions may be absent). Output: If there is a mistake in expression than the program will show the place of first mistake. If there is no mistakes - it will tell user if polynomials are the same or not after adduction ("Polynomials are the same" or "Polynomials are different").

Key -d for debugging Key -e for configuring of epsilon (used for comparison of numbers e.g. 0.004 and 0.003 are the same if epsilon is 1e-2)
