ConclusionLinklist *l and Linklist *lThe reference L is to change the value of L, and L points to the address of the head node of the list, that is, to change the address of the head node, but the general change chain is the node after the first node to operate, so the address of the head node has not changed, so remove the function can still be normal execution. is added, in case there is no link list is the case without a head node, because the fi

Elem,l.elem L->next, (*l) the difference between->nexttypedef struct node{int elem;struct node * NEXT;}node,*linklist;For linklist L:l is a pointer to the defined node struct, you can access the struct member by using the-e operator, that is, L->el

1. Brief introductionThe bottom of the linklist is actually a doubly linked list, the so-called list is a linklist internal static static class (node), all operations on linklist are essentially through the new Node object in LinklistMaking an association reference2, the implementation of a, construction method:Linklist provides a total of two construction method

In the previous article, I learned "sequence table (seqlist)". In this article, I will refer to "single-chain table (linklist )". At the end of the previous article, we pointed out that the sequence table requires a set of continuous memory space, and to ensure the sequence of elements, when inserting/deleting elements, the following elements must be moved. If you need to insert or delete elements frequently in your application, the overhead will be h

List is an interface, ArrayList and LinkedList are two implementation classes, they implement the same way, in fact LinkedList is the real chain list (if not clear what is linked list, need to understand the knowledge of related data structure, this is not one or two words can be said clearly), And ArrayList is implemented by an array, which is not a real linked list, it sets an initial capacity of an array at initialization time, and when there is not enough space, it will reconstruct a larger

When a single linked list is processed, the result is an ordered listSolution:Query the original linked list one by one, insert a new linked list, and sort the linked list at the same time as you insert it.

unsynchronized (unsynchronized). SummarizeIf it involves operations such as stacks, queues, and so on, you should consider using the list, for quick insertions, for deleting elements, should use LinkedList, and if you need to quickly randomly access elements, you should use ArrayList.Try to return the interface rather than the actual type, such as returning a list instead of ArrayList, so that if you need to change ArrayList to LinkedList later, the client code does not have to be changed. This
