Implement a method called evaluate:

static Double evaluate$($SinglyLinkedList polynomial, Double x$)$

This method should evaluate the polynomial for the given value of x and return the result.

For example, given polynomial $6\mathrm{.}0>0\mathrm{.}0>-5\mathrm{.}3>3\mathrm{.}1$ and x having value $7\mathrm{.}0$
