Well, very good questions... At least the idea is clever.First, we can obtain the property: for the adjacent two heap A B, it is meaningless for A to give B and then B to give... That is to say, only one-way transmission is allowed.Then we will write down the heap of hay a [I] each point.At the same time, we can calculate the del [I], which indicates that if the heap I transmits only to the right and the heap n does not run any hay to the heap 1st, the number of hay that I-1 transmits to IDel [

We know the ranking updated these days, the search engine spider crawling frequency will increase several times than usual. If the server stops updating in this time, will cause the spider cannot crawl your website, the search engine will think the website is out of trouble, even think this website already does not exist. Imagine the server if the search engine rankings update the duration of the stop update how serious the consequen
depth of the two nodes consistent, and then find the nearest common ancestor of Node 3 and node 5 (this operation will certainly not affect the result ). In this way, we perform path calculation on the two nodes at the same time. Their first pair of the same path points (still Node 2) is the closest common ancestor.
In fact, we can directly use a multiplier array to find the nearest common ancestor. (The following code is actually for the two nodes under the recent common ancestor. The recent
