Overview of the first phase of algorithm
As the first phase of algorithm training, it is not difficult. But as a normal algorithm learner. We should not be bound by the present, so we will talk about as many ways as possible. As a review of previous algorithm learning. The methods used here will be described in detail in other documents.

Give an undirected graph with \ (n \) points \ (m \) edges, and then ask \ (Q \) times. Each time you ask, \ (k \) edges will be given. You need to answer whether the undirected graph is connected or not after deleting the \ (k \) edges.
\(n\le 10^5,m\le 5\times 10^5,k\le 15\)
First, find out a \ (dfs \) tree, and co ...

Only two numbers in an array appear once, and all other numbers appear twice. Write a function to find the two numbers that only appear once. LeetCode: Once only numbers, title links
Output: 4, 5
Method 1: sort the array first, and then compare the adjacent numbers to see if they are the same. Figure:

Object oriented design
Like face detection and face recognition, face tracking consists of two parts: data and algorithm. The algorithm trains the model by storing (i.e. offline) data in advance, and then performs some operations on the new (i.e. online) data. Therefore, object-oriented design is a good choice.
In opencv 2.x version, it is conv ...

Now the math problems in primary school are not so interesting. Look at this winter vacation assignment. Each box represents a number from 1 to 13, but it can't be repeated.
□ + □ = □ □ - □ = □ □ × □ = □ □ ÷ □ = □
For example: and: 6 ...

We all know that the ray in UE is very important. We will use blueprint to add components
But I will not use C + + to add. Today, I will teach you how to use C + + code to realize it
UE version: 4.17
We create a C + + project to give empty
After startup, press F8 to select the default pawn and add a blueprint script
