In this lab, you are going to complete $2$ missing functions in the attached lab$2.$c$.$

Function makeListCircular updates the input$-$linked list into a circular$-$linked list.

There is no end to circular linked lists, function printCircularLinkedList prints the "numNodes" number of nodes in the circular linked list.

The sample output with "numNodes" $=20$ will be as follows:

Linked list:

$123456$

Circular linked list $20$ items

$12345612345612345612$

Linked list:

$1$

Circular linked list $20$ items

$11111111111111111111$

Linked list:

Circular linked list $20$ items

Please note that you will also add your implementation to the functions makeListCircular and printCircularLinkedList
