Given the following linked list and Node definition.

$1\mathrm{.}1[2$ pts$]$ As above shows, prv and current are pointers that are currently pointing to Node $17$ and $5$ respectively. Write a segment of $C++$ code to insert a new Node with value $4$ after the current node and update the two pointers prv and current accordingly $($i$.$e$.$ current should point to Node $4$ and prv should point to $5$ instead$).$
