Given a pointer to the head of a linked list and a specific position, determine the data value at that position. Count backwards from the tail node. The tail is at postion 0, its parent is at 1 and so on. Example head refers to 3 → 2 → 1 → 0 → NULL positionFromTail = 2 Each of the data values matches its distance from the tail. The value 2 is at the desired position. Function Description Complete the getNode function in the editor below. getNode has the following parameters:
