      "sc1": "Let's look at the data members for class <code>LList</code>.",
      "sc2": "First, notice that class <code>LList</code> implements the <code>List</code> interface. This means that <code>LList</code> is required to give implementations for all of the methods listed as part of the <code>List</code> interface.",
      "sc3": "The first private data member is <code>head</code>, which points to the first node of the list. The header is a link node like any other, but its value is ignored and it is not considered to be an actual element of the list.",
      "sc4": "The second private data member is <code>tail</code>, which points to the trailer node. The trailer is a link node like any other, but its <code>next</code> field is set to <code>null</code>. Like the header node, the trailer node's value is ignored.",
      "sc5": "<code>curr</code> points to the current node of the list. It could be any node on the list other than the <code>head</code> node. If <code>curr</code> points to the same node as <code>tail</code>, then <code>curr</code> is at the end of the list. In this case, a newly inserted node would go to the end (but before the trailer).",
      "sc6": "Since there is no simple way to compute the length of the list simply from these three pointers, the list length is stored explicitly in <code>listSize</code>, and updated by every operation that adds or removes a node.",
      "sc7": "Because <code>head</code>, <code>tail</code>, <code>curr</code>, and <code>listSize</code> are all declared to be <code>private</code>, they may only be accessed by methods of Class <code>LList</code>."
