Sparse Polynomial representation and addition

Sparse Polynomial representation and addition: Polynomial is an expression which is composed of terms, wherein terms are composed of coefficient and exponent.  An example of a polynomial is: 4×3+5×2+6x+9.  This polynomial is composed of four terms with the following sets of coefficient and exponent – {(4,3), (5,2), (6,1), (9,0)}.  Thus representation of a polynomial using …
