/*OUTPUT


 How Many Degree: 3

 Enter The Polynomial Order:

 Enter Coeff of Degree x^3: 2


 Enter Coeff of Degree x^2: 4


 Enter Coeff of Degree x^1: 3


 Enter Coeff of Degree x^0: 1


 Polynomial is: 2x3 + 4x2 + 3x1 + 1x0

 Enter Value For x : 2


 Evaluation of Polynomial: 39



 How Many Degree: 2

 Enter The Polynomial Order:

 Enter Coeff of Degree x^2: 2


 Enter Coeff of Degree x^1: 3


 Enter Coeff of Degree x^0: 1


 Polynomial is: 2x2 + 3x1 + 1x0

 Enter Value For x : 2


 Evaluation of Polynomial: 15 */
