Implement a method called display:

static void display$($SinglyLinkedList polynomial$)$

This method should print the polynomial in proper polynomial format.

For example, displaying polynomial $6\mathrm{.}0>0\mathrm{.}0>-5\mathrm{.}3>3\mathrm{.}1$ should result in $6\mathrm{.}0$x$^3-5\mathrm{.}3$x $+3\mathrm{.}1$ being printed.
