Matrix Admin Background Template notes

A background template I want to change it for a long time. The Matrix Admin was found last time. Like Ace, it's bootstrap style and easy to get started with. The matrix needs to be more robust. It is also possible to feel the user interface.Overall style:1. Form validationValidation is aided by the jquery.validate.js. There are rich authentication methods, more A

Matrix Multiplication Template Class header file C ++

This is followed by an implementation of the multiplication sequence of the query matrix in the previous article. This class can accept input and calculate the final result. Because I recently learned C ++, I naturally wrote this thing as a class and implemented it in template mode. It is indeed very neat. // Matrix. h

[Ultraviolet A] 11992-Fast Matrix Operations (line segment tree template)

The basic line segment tree should be noted that, due to the set and add operations, when the push-down is marked as lazy, the set is given priority, and then the ADD is given priority. Each time you execute the set operation, the ADD is marked as 0. Wa has been used several times because of a problem during the Computing period. The funny thing is that I found the template for more than an hour. # Include [Ultraviolet A] 11992-Fast
