Many people regard it as a symptom of I/O problem, I myself every once in a while will encounter to%iowait nervous of customers, have to try to explain repeatedly, in fact, this indicator contains very little information, can not
The iteration of a node in a non-permission graph gets all the paths from the starting node to the end node and obtains the shortest path from the node. Because it is a power-not graph, all the path weights can be treated as 1. Just need to get all the possible paths with the smallest number of nodes is the shortest pa
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 n

The NextSibling property returns the node immediately following a node (in the same tree hierarchy) PreviousSibling property returns the node immediately before a node (in the same tree hierarchy).
