For my current project, I have to write a method that checks to see if one linked list is equal to another. They must be the same length, but the nodes don't have to be in the same spot. AKA 1 3 8 is equal to 1 8 3 But the problem is I can't think up a wa...
也就是说我们是用数组实现的Stack,今天我们学习一个和Stack同样重要的数据结构Queue,前面学习LinkedList 的时候我们注意到了LinkedList它其实实现了Queue 接口的,所以我们可以将LinkedList当做Queue来使用,那么其底层实现就是LinkedList的实现,也就是链表。 Queue 的定义 我们看到List ,Set 和 Queue 都是Java 集合框架的顶...
