首先，给你个实现类：/*** SkipList.java ***/import java.util.Random;public class SkipList<T extends Comparable<? super T>> { private int maxLevel;private SkipListNode<T>[] root;private int[] powers;private Random rd = new Random();SkipList() { this(4);} SkipList(int i...
1、Skip list层次的选择:插入列的“高度”较前者来说显得更加重要,也更加难以确定。由于它的不确定性,使得不 同的决策可能会导致截然不同的算法效率。为了使插入数据之后,保持该数据结构进行各种 操作均为O(logn)复杂度的性质,我们引入随机化算法(Randomized Algorithms)。我们定义一个随机决策模块,它的大致内容如下...
A Java implementation ofskip list. 跳表的Java语言实现。 Introduction Skip lists are data structures that use probabilistic balancing rather than strictly enforced balancing. As a result, the algorithms for insertion and deletion in skip lists are much simpler and significantly faster than equivalent alg...
java8新特性-引用流-skip,limit skip跳过指定数量的元素,limit返回指定数量的元素。可以用来对少量数据的分页。 例子 List<User>users=newArrayList<>(); users.add(newUser("张三",30)); users.add(newUser("李四",39)); users.add(newUser("王五",20));...

A search for a target element begins at the head element in the top list, and proceeds horizontally until the current element is greater than or equal to the target. If the current element is equal to the target, it has been found. If the current element is greater than the target, or...
