chapters.(i) Newton's first lawAccording to Newton's first law--the law of inertia, any object should be kept uniform motion or stationary until the force forces it to change the state of motion, and plainly, that is, the motion of an object without any force, its velocity and direction are unchanged, expressed in a formula:With the above formula, we can draw the displacement-time curve of uniform motion:I
How does the Labor Law regulate resignation?
A:
1. The employee must notify the employer in writing 30 days in advance of resignation:
Article 31st of the Labor Law of the People's Republic of China stipulates that "a laborer who terminates a labor contract shall notify the employer in writing 30 days in advance", and clearly gives the employee the right to resign. This right is absolute, the laborer uni
At first, I thought this question was a raw question about the rapid power of the matrix,
Later it was found that it would time out, and the super would exceed M = C ^ (N * n). This operation, and the C itself is a matrix of N * n, with N at the maximum of 1000.
But here is a clever place: the source of C is actually = a * B. A is a matrix of N * k, and B is a matrix of K * n, K is up to 10. Here is the breakthrough. The combination Law of the matrix

birth let them come to live not come over, and this time I was abortion, not to come, these realities I understand, but if people only use rational life Then there is no need to form a family, and there is no love and hate.When my son was born, no one was in control, I refused to pick up the phone from my in-laws after the baby was born, but the joy of the child's birth was watered down by the children at that time. And this abortion, I was angry because they advised my husband not to leave the
the obtained sequence is [1, 2, 1, 3, 1, 2, 1]. The number on the second position is 2. The second sample the obtained sequence is [1, 2, 1, 3, 1, 2, 1, 4, 1, 2, 1, 3, 1, 2, 1]. The number on the eighth position is 4. IdeasTest instructionsThere is a sequence, consisting of a number of 1-n, the first element is 1, then the sequence obtained in the previous step is added to the back and the number of n is inserted in the middle of the number of unused minimum number, ask what is K.ExercisesThe s
This is the story I saw in an article on Tujia:
Sao Paulo, Brazil, has a town named yarama. There is a strange law in the town of yarama: if one of the people living in this town steals food from poverty, all the adults in this town will be fined RMB 5, and All fines will be used for charity. This rule originated from one thing that occurred in the town of yarama in 1968:
In 1968, Arama, an old woman begging on the street was caught while stealing b

Some mathematical symbols
Do not confuse data with computer programming symbols.
For example, in the flip die example, the probability of 2 or 4 points is calculated as: P (2 then 4) = P (2) + P (4 ), this is the Union symbol, which is equivalent to "or", and the intersection symbol is "and", which is different in Chinese and English.
Another example is flip 2 dice, which adds up to seven points. The probability of one point and one six points is obtained, and P (
If you think that success is possible only when you are busy and busy, you are wrong.Things always develop in a complicated direction, and complexity will lead to waste, while efficiency comes from simplicity. Most of the things you have done may be meaningless. A truly effective activity is only a small part, and they are usually hidden in complicated things. Finding the key and removing unnecessary activities is not that complicated.Occam Razor: do not add any entity if necessary.In the 12th c

For more information about the features, concepts, attributes, and implementations of heap, see the above two articles.
What can heap do from the perspective of variable governance and problem simplification?
1) priority queue
2) Heap sorting
On the basis of implementing the heap, these two are also very simple.

In the face of our little experience in software development, this book, software engineering is no longer dull, but it becomes surprisingly lively and interesting. Learn a lot of professional courses, such as algorithms, data structures, compiling principles, software engineering and so on. Our classmates may have this question in mind: what is the use of learning so many lessons? How many of them are actually applied to the job? In other words, we all feel that there is an insurmountable gap b
Thoughts on reading the Law of constructionQuestion: Where can we begin to develop our own development thinking and ability at this stage?Question: How do you know if your innovation will win everyone's approval?Question: In unit testing, do you have to ask for code coverage of up to 100%?Question: Should we be a real software engineer before we graduate?Question: Can the teamwork and development process be divorced?"The
Recently read through the "Construction of the Law", this book from the author and many universities in the country to carry out software engineering co-operative teaching experience accumulated, the book introduces many IT industry is using the theory and technology, and from these new ideas, new technologies to summarize their work in the future useful things. The following is my experience and doubts about reading "Some of the
Thoughts on the first reading of the Law of constructionAfter reading the first two chapters of the Law of construction, I was touched. Chapter One or two is mainly about the introduction of modern software engineering and personal technology and processes. The main idea of the book is "doing High school". First of all, software = engineering + programs, made out of the software has a variety of uses, softw
Read the 11th, Chapter 12 of the Law of constructionToday, I read 11, 12 chapters of the Law of Construction, the 11th chapter mainly discusses the software design and implementation of some knowledge, tell us how specifically to develop a software. and the 12th chapter introduces the user experience of the relevant knowledge, some people think that the user interface is to do some optimization, so that the
Software engineering This discipline has been boring boring, so has not been interested in in-depth research, because this semester opened a software engineering this course, plus Yang GUIFAO Teacher's recommendation, I bought Xin Zou Teacher's "Construction of the law-modern software Engineering", a few days to carry out a rough reading, But it has completely aroused my interest in software engineering, for personal development, two people developmen
