我将添加另一个-列表可以充当纯函数式数据结构。

例如，您可以让完全不同的列表共享相同的结束部分

a = (1 2 3 4, ....)
b = (4 3 2 1 1 2 3 4 ...)
c = (3 4 ...)

例如:

b = 4 -> 3 -> 2 -> 1 -> a
c = a.next.next  

不需要把a指向的数据复制到b和c中。

这就是为什么它们在函数式语言中如此受欢迎的原因，函数式语言使用不可变变量——前置和尾部操作可以自由发生，而无需复制原始数据——当您将数据视为不可变时，这是非常重要的特性。

数组和链表之间的区别在于，数组是基于索引的数据结构，每个元素都与一个索引相关联，而链表是使用引用的数据结构，每个节点都被引用到另一个节点。在数组大小是固定的，而在链表大小是不固定的。

Arrays make sense where the exact number of items will be known, and where searching by index makes sense. For example, if I wanted to store the exact state of my video output at a given moment without compression I would probably use an array of size [1024][768]. This will provide me with exactly what I need, and a list would be much, much slower to get the value of a given pixel. In places where an array does not make sense there are generally better data types than a list to deal with data effectively.

While many of you have touched upon major adv./dis of linked list vs array, most of the comparisons are how one is better/ worse than the other.Eg. you can do random access in array but not possible in linked list and others. However, this is assuming link lists and array are going to be applied in a similar application. However a correct answer should be how link list would be preferred over array and vice-versa in a particular application deployment. Suppose you want to implement a dictionary application, what would you use ? Array : mmm it would allow easy retrieval through binary search and other search algo .. but lets think how link list can be better..Say you want to search "Blob" in dictionary. Would it make sense to have a link list of A->B->C->D---->Z and then each list element also pointing to an array or another list of all words starting with that letter ..

A -> B -> C -> ...Z
|    |    |
|    |    [Cat, Cave]
|    [Banana, Blob]
[Adam, Apple]

Now is the above approach better or a flat array of [Adam,Apple,Banana,Blob,Cat,Cave] ? Would it even be possible with array ? So a major advantage of link list is you can have an element not just pointing to the next element but also to some other link list/array/ heap/ or any other memory location. Array is a one flat contigous memory sliced into blocks size of the element it is going to store.. Link list on the other hand is a chunks of non-contigous memory units (can be any size and can store anything) and pointing to each other the way you want. Similarly lets say you are making a USB drive. Now would you like files to be saved as any array or as a link list ? I think you get the idea what I am pointing to :)

链表

它更可取的时候，它涉及到插入!基本上它所做的就是处理指针

1 -> 3 -> 4

插入(2)

1... 3... 4 ... 2

最后

1 -> 2 -> 3 -> 4

一个箭头指向3点，另一个箭头指向2点

简单!

但是来自Array

| | 1 | 3 | 4

插入(2) | 1 | 3 | | 4 | | 1 | | 3 | 4 | | 1 | 2 | 3 | 4 |

任何人都可以想象出其中的不同! 对于4个索引，我们执行3个步骤

如果数组长度是一百万呢?数组有效吗? 答案是否定的!：）

删除也是一样! 在链表中，我们可以简单地使用指针并将对象类中的元素和next置空! 但对于数组，我们需要执行shiftLeft()

希望有帮助!：）

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
