I recently saw some good C speech algorithms on the Internet. Enumerate and use them for your own learning. Some interesting algorithms include different implementations of C. Question 1: How many three numbers can be composed of 1, 2, 3, and 4 numbers that are different from each other and have no repeated numbers? What is it?

existence, then c[2]=true, to C mark trueA[3]=false, there is no. False is marked in CIf you have a maximum of 99999, then this array will be so long you can directly set to 99999, wasting a bit of space;If you can find the maximum value directly in your business, it's the best. Try it yourself. This idea is very simple to understand. The Netizen also quickly understood, after a while to tell me the result of his.Down to about

In addition to the unreliable network, the hybrid transmission of telecommunication and broadband services also brings the risk of network attacks. In addition, LTE requires interconnection between NodeB, while the OLT has a strong L2 aggregation function, and the layer-3 forwarding function between branches

green page will be PageRank swallow. Larry page calls this situation rank Sink.What if the links along the page keep going and find that you're always wandering around the same few pages? Yes, turn off the current page and open a new page. This is just like rank Sink, which means you can use this idea to solve rank Sink. Therefore, in the formula (3) based on the addition of an escape factor E, get:(5)E (i) means of escape factor for page ITo turn (5
