of the loop will continue to exit recursively, the value of board[i][j] will change, so the results are very strange when the recursion is rolled out.In fact, there is a method at night, the idea is similar, just to change the DFS () function to return the value, but no longer void.

belong to the SOCKS protocol, but they are different because they support different applications. The socks4 proxy only supports TCP applications, while the SOCKS5 proxy can support TCP and UDP applications. However, because the SOCKS5 Proxy also supports various authentication mechanisms, such as server-side domain name resolution, but the socks4 proxy does not, Socks proxy is usually open to the outside. Therefore, generally, UDP applications are not supported. That is to say, socks4 can work

Solution The result outputs a line of magnetic induction intensity curve, and all the results are stored in the result_linein.dat file, while the curve name is defined as the value of linein + nvalue, through this, we can easily distinguish the meaning of each curve.
