Obligation:
need to prove termination of the following program:
package FlattenTreeListRec;

public class FlattenTreeListRec {
  public static void main(String[] args) {
    Random.args = args;
    int listLength = Random.random();
    TreeList list = null;
    for (int i = listLength; i > 0; i--) {
      Tree tree = Tree.createTree();
      list = new TreeList(tree, list);
    }

    flatten(list);
  }

  public static ObjectList flatten(TreeList start) {
      if (start == null) {
        return null;
      } else {
        Tree tree = start.value;
      if (tree != null) {
        Object value = tree.value;
        start = start.next;
        start = new TreeList(tree.left, start);
        start = new TreeList(tree.right, start);
        return new ObjectList(value, flatten(start));
      } else {
        return flatten(start.next);
      }
    }
  }
}


package FlattenTreeListRec;

public class ObjectList {
  Object value;
  ObjectList next;
