Some operations of the C # list (whether the two list elements want to be the same, whether the list is contained in another list)

First, the fake has two ListList1.all (list2.contains) List1.count = = List2.countSecond, how to determine whether the list in C # is complete with another listBOOL Iscontainsall (list listb) { return listb.all (b = Lista.any (A = a.equal (b)));If the list contains standard data types, it is easier to change a.equal (b) to a==b.Some operations of the C #

Given a list of linked lists, each node of the list contains three attributes: 1, node value, 2, reference to the next node, 3, a reference to any node in the list, or not to any node. Copy the linked list

Idea: The difficulty of this algorithm is difficult to have a reference to a random node in the list, you can not determine which node the reference points to, but we can use the choice of reference to solve the problem. Using the original linked list as a reference, head is a node of the original list, and the next of this node is the one that is down, but now w

~ sunny 7~ Day */ ? Usage of 2.listLet's see what the API says.Like Array (), this is not a real function, but a language structure. List () assigns a set of variables in one-step operation.Take a look at an example: list($a,$b)=array(10,20);echo$a,'~',$b,'';//返回10~20?> Yes, you can assign values to a set of variables.Let's look at another example:
