In modern physics, temperature and humidity data are very important in many fields, and the calculation and analysis of various temperature parameters are particularly important, such as average temperature, maximum temperature, minimum temperature, average kinetic temperature, etc., the calculation of various temperature data can not be separated from the analysis of a large number of temperature data, And how to get a lot of temperature data, in tod
My answer, but the complexity is not very satisfied, is an exponential level of complexity. But the test data is weak, or AC. Found on the Internet, are brute force solution, do not know whether there is a better solution.Two errors were made in the solution, the first, map#include Programming-challenges Crypt Kicker (110204)
This problem is much easier than its brother, "843-crypt Kicker ". just find the key line and get the translate table from it will do all the job. I generate a "signature" for the key line to make the search easier. by the way, pay attention to blank line cases.

Then create a new/SRC under the/arbotix_ros folder, cut all other files to/SRC, and then use Catkin_make to compile the sourc
I wrote a demo to simulate the elastic collision of small balls and posted it first.
Scenario Description:
Randomly generate n balls, random initial speed, initial direction, quality, size, and color.
Each ball is regarded as a particle. The collision between the ball and the ball, the ball and the wall is elastic (I .e., after the collision, the X and Y axes are reversed, and the size remains unchanged), and kinetic energy conservation.
