为什么有人想要使用链表而不是数组?
毫无疑问，编码一个链表比使用数组要多一些工作，人们可能会想知道如何才能证明这些额外的工作是合理的。
我认为在链表中插入新元素是微不足道的，但在数组中这是一个主要的任务。与将数据存储在数组中相比，使用链表存储一组数据还有其他优点吗?
这个问题不是这个问题的重复，因为另一个问题是专门问一个特定的Java类，而这个问题是关于一般数据结构的。

Eric Lippert最近发表了一篇关于数组应该保守使用的原因之一的文章。

我也认为链表比数组更好。 因为我们在链表中做遍历，而不是在数组中
对我来说是这样的，
Access Linked Lists allow only sequential access to elements. Thus the algorithmic complexities is order of O(n) Arrays allow random access to its elements and thus the complexity is order of O(1) Storage Linked lists require an extra storage for references. This makes them impractical for lists of small data items such as characters or boolean values. Arrays do not need an extra storage to point to next data item. Each element can be accessed via indexes. Size The size of Linked lists are dynamic by nature. The size of array is restricted to declaration. Insertion/Deletion Elements can be inserted and deleted in linked lists indefinitely. Insertion/Deletion of values in arrays are very expensive. It requires memory reallocation.
合并两个链表(特别是两个双链表)比合并两个数组快得多(假设合并是破坏性的)。前者取O(1)，后者取O(n)。
编辑:澄清一下，我在这里指的是无序意义上的“合并”，而不是归并排序。也许"串联"这个词更合适。
It's easier to store data of different sizes in a linked list. An array assumes every element is exactly the same size. As you mentioned, it's easier for a linked list to grow organically. An array's size needs to be known ahead of time, or re-created when it needs to grow. Shuffling a linked list is just a matter of changing what points to what. Shuffling an array is more complicated and/or takes more memory. As long as your iterations all happen in a "foreach" context, you don't lose any performance in iteration.
在数组中，您有权限在O(1)时间内访问任何元素。所以它适用于二进制搜索、快速排序等操作。链表则适合于插入删除，因为它在O(1)时间内。两者都有优点和缺点，选择一种而不是另一种归结为您想要实现什么。
—更大的问题是，我们能有一个两者的混合体吗?类似于python和perl实现的列表。
