< p > 内存空间是所有程序的公共资源，在一个复杂的系统运行环境下，空闲的内存空间可能散落在内存各处。我们知道，存储数组的内存空间必须是连续的，而当数组非常大时，内存可能无法提供如此大的连续空间。此时链表的灵活性优势就体现出来了。< / p >
< p > 「链表 Linked List」是一种线性数据结构， ， ， ， < / p >

< p > 观察上图，链表中的每个「节点 Node」对象都包含两项数据： < / p >
< ul >
< li > 链表的首个节点被称为“头节点”，最后一个节点被称为“尾节点”。< / li >
< li > 尾节点指向的是“空”，它在 Java, C++, Python 中分别被记为 < span class = "arithmatex" > \(\text{null}\)< / span > , < span class = "arithmatex" > \(\text{nullptr}\)< / span > , < span class = "arithmatex" > \(\text{None}\)< / span > 。< / li >
< li > 在 C, C++, Go, Rust 等支持指针的语言中，上述的“引用”应被替换为“指针”。< / li >
< / ul >
< p > 如以下代码所示，链表以节点对象 < code > ListNode< / code > 为单位，每个节点除了包含值，还需额外保存下一节点的引用（指针）。因此在相同数据量下，< strong > 链表通常比数组占用更多的内存空间< / strong > 。< / p >

< p > < strong > 单向链表< / strong > 。即上述介绍的普通链表。单向链表的节点包含值和指向下一节点的引用两项数据。我们将首个节点称为头节点，将最后一个节点成为尾节点，尾节点指向空 < span class = "arithmatex" > \(\text{None}\)< / span > 。< / p >
2023-04-09 04:35:05 +08:00
< p > < strong > 环形链表< / strong > 。如果我们令单向链表的尾节点指向头节点（即首尾相接），则得到一个环形链表。在环形链表中，任意节点都可以视作头节点。< / p >
2023-08-17 05:12:16 +08:00
< p > < strong > 双向链表< / strong > 。与单向链表相比，双向链表记录了两个方向的引用。双向链表的节点定义同时包含指向后继节点（下一个节点）和前驱节点（上一个节点）的引用（指针）。相较于单向链表，双向链表更具灵活性，可以朝两个方向遍历链表，但相应地也需要占用更多的内存空间。< / p >

< p > 单向链表通常用于实现栈、队列、散列表和图等数据结构。< / p >
< ul >
< li > < strong > 栈与队列< / strong > ：当插入和删除操作都在链表的一端进行时，它表现出先进后出的的特性，对应栈；当插入操作在链表的一端进行，删除操作在链表的另一端进行，它表现出先进先出的特性，对应队列。< / li >
< li > < strong > 散列表< / strong > ：链地址法是解决哈希冲突的主流方案之一，在该方案中，所有冲突的元素都会被放到一个链表中。< / li >
< li > < strong > 图< / strong > ：邻接表是表示图的一种常用方式，在其中，图的每个顶点都与一个链表相关联，链表中的每个元素都代表与该顶点相连的其他顶点。< / li >
< / ul >
< p > 双向链表常被用于需要快速查找前一个和下一个元素的场景。< / p >

2023-07-19 16:10:17 +08:00
< li > < strong > 浏览器历史< / strong > ：在网页浏览器中，当用户点击前进或后退按钮时，浏览器需要知道用户访问过的前一个和后一个网页。双向链表的特性使得这种操作变得简单。< / li >
< li > < strong > LRU 算法< / strong > ： （ ） ， ， < / li >
< / ul >
< p > 循环链表常被用于需要周期性操作的场景，比如操作系统的资源调度。< / p >
< ul >
< li > < strong > 时间片轮转调度算法< / strong > ：在操作系统中，时间片轮转调度算法是一种常见的 CPU 调度算法， ， ， < / li >
< li > < strong > 数据缓冲区< / strong > ：在某些数据缓冲区的实现中，也可能会使用到循环链表。比如在音频、视频播放器中，数据流可能会被分成多个缓冲块并放入一个循环链表，以便实现无缝播放。< / li >
