It is not very difficult to see an algorithm question on the Internet. There are also solutions for searching, but there are usually several layers of for loops. I tried to write it down.

Running result:
Obtain a solid root of the high equation 2x ^ 4-4x ^ 3 + 6x ^ 2-8x-8 = 0 (accuracy requirement: 10 ^-3)
Algorithm analysis is as follows: There are many real-root algorithms for High-Level equations. Here we introduce a kind of bipartite method.
If the higher-order equation f (x) is set to 0, a real root algorithm is obtained using the bipartite method as follows
[Boiled ASP. NET Web API2 methodology] (3-2) Direct routing/attribute routing, api23-2
Problem
How can I define a route in a way closer to a resource (Controller or Action.
Solution
You can use Attribute routing to directly declare a route at the resource level. You only need to simply use RouteAttribute on the Action, and then pass a relevant routing template.
permissioned setting, but his communication is at least squared, and obviously is hard to support large network nodes, even in permissioned setting. According to colleague Test, the Hyperledger 100 nodes are about to finish the egg ... PBFT is the abbreviation of practical Byzantine Fault tolerance, which means a practical Byzantine fault-tolerant algorithm. This algorithm is proposed by Miguel Castro (Castro) and Barbara Liskov (Liskov) in 1999, which solves the problem of inefficient origin

What is the result of a certain convincing pen question in a certain year? The answer is 4. Why?
My understanding (do not know if it is correct ):
A is an array pointer of the int type [5], so a plus 1 is actually a + sizeof (int) * 5, that is, a [5], forced conversion to int
