(2) Inserting a new element in an array of elements is expensive, because room has to be created for the new elements and to create room existing elements have to shifted. For example, suppose we maintain a sorted list of IDs in an array id[]. id[] = [1000, 1010, 1050, 2000, 20...

By amortizing space overhead over several elements, an unrolled linked list can achieve very close to the compactness of an ordinary array. The overhead per element is proportional to 1/N, and in practice is at most a few bits per element. We can adjust N to trade off compactness and ...
其中 getArrayLists 函数会返回不同 size 的 ArrayList,getLinkedLists 函数会返回不同 size 的 LinkedList。 loopListCompare 函数会分别用上面的遍历方式 1-5 去遍历每一个 list 数组(包含不同大小 list)中的 list。 print 开头函数为输出辅助函数。
