Title DescriptionA linked list contains the ring, please find the link to the list of the entry node.Thinking Analysis:The first step is to find the loop in the meeting point. Using P1,P2 to point to the list head, p1 each step, p2 each walk two steps, until P1==P2 find the meeting point in the ring.Step two, find the
Today this has been playing for a long time, it was thought that the data structure is that, but a kind of thinking, but actually the actual play and imagine the gap is very large, need to take into account various details.Today's question has a more interesting application, that is, "Joseph Ring problem."Specifically, you can see Baidu Encyclopedia:Http://baike.baidu.com/link?url=poA1Aanlptc6yzP1puYhSw_0RQjRAplhPfHwk6eoiqMNxw6WigCEbexxZ8a9SUbrMGokpPb

Add a link to a list groupBy using anchor tags instead of list items, we can add links to list groups. We need to use Bootstrap experience Example: adding a link to a list group

For single-linked lists, we use pointers most of the time (refer to a single linked list based on pointer implementations). Now let's see how to use arrays to implement single-linked lists.1. Define data structures for nodes in a single-linked list1typedefintElementType;2 classNodeType3 {4 Public:5 ElementType data;6 intNext;7};The node consists of two elements, one of which is the data, and the other refers to the "pointer" to the next node (in
, with a constructor below: Public link () { thisnull; }The head node is created, and when the object references the tool class, the head node is defined, so here's a way to create a circular list: Public voidFun () {Scanner s=NewScanner (system.in); System.out.print ("Please enter a list length, enter as a pure number:"); intValue =Integer.parseint (S.
essence of these problems is how to find the node with "edge. We can solve this problem by using a deformation in method 3: Boolean has_loop(Node *head) { Node *pf = head; /* fast pointer */ Node *ps = head; /* slow pointer */ while(true) { /* step 1, is there a loop? */ if(pf pf->next) pf = pf->next->next; else return FALSE; ps = ps->next; if(ps == pf) break; } /* step 2, how long is the loop */ int i = 0; do
