Open your computer every day. The first thing you need to do is to open the most common software: contact your friends, Open QQ, receive emails, open outlook, and listen to music, you opened the cool dog ...... But you don't want to be a robot. You repeatedly open these software every day, so you let them start up. Congratulations, you have the basic idea of not making robots. These simple and repetitive operations should be thrown to the computer. Yo
Given a square, each point in the grid is composed of an open space, lawn, and a wall. A robot can be placed in each blank space, and each robot can scan the laser in four directions, therefore, a solution should be given to place enough robots on the board. The laser can pass through the lawn but cannot pass through the wall.
Solution: in fact, this is a classic binary match diagram. The practice is to split rows and columns, that is, if a row contai
Our robots are different from our products. Basically, they are non-standard and customized based on different users. They are basically newly developed, so they have not been honed for a long time. A common phenomenon has recently been found. That is, we tend to be good in the debugging process. But at the crucial moment-when leaders or foreign guests visit, machines will be like the magic at that time, and such problems will occur. You must know tha

This is because coordinates are used only when robots are defined, and coordinates are not used in commands.
Then I thought like this, in terms of process processing, I still use the array coordinate system, while doing some conversions during input and storage.
