Today I learned about the Boost file traversal feature, and found that the GNU compiler has the-MM option to automatically generate dependencies, so I wrote a makefile generator with the above two points. You can generate makefile for a generic single executable file, using the Windows+mingw+boost environment. If you're using Linux, you just need to change Del to RM related operations at the two system calls in the program and the Clean Tag generator.

P4035 [JSOI2008] Spherical space generator title
Main topicThe n+1 points on the n-dimensional space are given, and the stores are on a round surface, seeking the coordinates of the circle center.Defined:
Sphere: A point of equal distance to any point on the sphere.
Distance formula between two points
\[A (x_1,x_2,x_3,x_4,\cdots x_n) \]\[B (y_1,y_2,y_3,y_4,\cdots y_n) \]\[Distance:\sqrt[2]{\sum_{i=1}^{n} (x_i-y_i) ^2} \]
rows greater than line I from the main element of this column. It is important to note that the main element should not be 0 and not very small, otherwise it will seriously affect the accuracy (that is, if it is small, it cannot reflect the denominator). So we are going to find the largest of column I, and then exchange it with the current line at each elimination, so that we can get the maximum main element.The problem of determining the non-solution and infinite solutions in Gauss is still to

The upper limit of this problem is 100000, the time to find the smallest generator in 100,000 numbers is too high, and there is a limit to the sample number, even if the algorithm is more concise to write time out. Therefore, the way to solve the problem by using the table method, but there is still a problem, that is, if you find from 1 to 100000 is still very time-consuming, then, Rujia words to understand the direction ——— to find out the

When building a front-end project, using yeoman generator can help us complete repetitive operations such as creating files, installing modules, and class libraries. However, existing generator sometimes cannot meet our needs, so you can use yeoman's API to build your own
Python yield Introduction
What is a generator function?A generator function is a function that remembers where the last function returned, and saves some states of the function at that time, such as variables, objects in the function field, and so on, which can then be executed the next time the function is executed.The builder owns the next method and behaves exactly like an iterator, which means that the
