void CLL::removeNext(SNode *n) {
// Longest method – given node n, remove the next node in thelinked list.
// you have 4 conditions:
//1: there’s only one node in the list, in which case you deletethat node and set the size to 0
//2: n’s next node is a last node, in which case n becomes the newlast node and n’s next must point // to the first node in the list(remember to decrease the size of the list)
//3: n’s next node is the first node in the list (i.e., n is thelast node in the list), in which case
// n’s next becomes first’s
