< p > 内存空间是所有程序的公共资源，排除已被占用的内存空间，空闲内存空间通常散落在内存各处。在上一节中，我们提到存储数组的内存空间必须是连续的，而当我们需要申请一个非常大的数组时，空闲内存中可能没有这么大的连续空间。与数组相比，链表更具灵活性，它可以被存储在非连续的内存空间中。< / p >
< p > 「链表 Linked List」是一种线性数据结构， ， ， < strong > 由于指针记录了下个节点的内存地址，因此无需保证内存地址的连续性< / strong > ，从而可以将各个节点分散存储在内存各处。< / p >

< p > 在编程语言中，数组整体就是一个变量，例如数组 < code > nums< / code > ，包含各个元素 < code > nums[0]< / code > , < code > nums[1]< / code > 等等。而链表是由多个节点对象组成，我们通常将头节点当作链表的代称，例如头节点 < code > head< / code > 和链表 < code > head< / code > 实际上是同义的。< / p >

< p > < strong > 链表访问节点效率较低< / strong > 。如上节所述，数组可以在 < span class = "arithmatex" > \(O(1)\)< / span > 时间下访问任意元素。然而，链表无法直接访问任意节点，这是因为系统需要从头节点出发，逐个向后遍历直至找到目标节点。例如，若要访问链表索引为 < code > index< / code > （即第 < code > index + 1< / code > 个）的节点，则需要向后遍历 < code > index< / code > 轮。< / 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指针（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 < span class = "arithmatex" > \(\text{null}\)< / 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 >
< 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指针（引用）。双向链表的节点定义同时包含指向后继节点（下一节点）和前驱节点（上一节点）的指针。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 >
