. Personally, DI should be a more specific name. I can imagine that in many cases when I use IOC, the final mode is focused on solving dependencies (for example, from a console application to a window event loop ). However, if you are more familiar with IOC, you can basically replace di in the following article with IOC. There are multiple types of IOC, such as category 1, Category 2, and category 3. The differences between these categories are notWithin the scope of this article.Note that I hav

The connect function will send all network protocol stacks until the data is sent to the network by the network adapter, and then sleep waiting for the confirmation signal sent back from the distance, and then send a signal to the remote end that receives the confirmation signal, this completes the establishment of a link. After that, all the data of this so
You can use common virtual functions to provide default behavior.To prevent new Derived classes from having different behaviors but forgetting to override, you can declare pure virtual functions and provide default implementations.This implementation must be explicitly called through the class domain.(If the pure virtual function is not implemented, other derived classes with common behaviors must write redundant duplicates.Code.)

from Nanjing to Guangzhou: berth pass (adult), 367 (middle Shop), and 458 (lower shop + handling fee) for train tickets from Beijing to Guangzhou ). That is to say, the fare of China Southern Airlines is already lower than that of train tickets. However, with the airport tax and the airport bus price in two locations (50 + 18 + 16 = 84), it is about 50 yuan more expensive than the train ticket.

participle, such as we can join domain Knowledge, you can add a known dictionary information, and so on.Maximum entropy Markov model MEMM (maximum-entropy Markov model)One problem of the maximum entropy model is that the labeling problem of each word is divided, so the wise man combines the Markov chain and the maximum entropy to get the maximum entropy Markov model, which can not only utilize the characteristics of the maximum entropy of various feature, but also add the serialized information
random process: My understanding is a collection of random variables. For example, X (t) =acos (wt+θ), T>=0,a,w is constant, and θ is a random variable that is evenly distributed on [0,2π]. For a fixed t,x (t) is a random variable, It is the function of theta. Since θ is a random variable, its function is also a random variable. For different t, such as T1,T2. X (T1), X (T2) is two different random variables. So you just need to understand the concept of random variables, the stochastic process

1. How many planes are required (it is said that it is Microsoft's interview question)
Each plane has only one fuel tank, and the planes can refuel each other (note that there is no fuel dispenser). A box of oil can be used for an airplane to fly around the Earth for half a lap.
Q: How many planes are required to take at least one plane round the earth and return to the airport when it starts to fly?
(All planes take off from the same
