串口通信(支持字符串以及十六进制)

TCP和UDP socket编程，向固定服务器发送学号姓名信息，用udp从服务器获得一个随机字符串(TCP and UDP socket programming, Student ID Name information sent to the fixed server udp from server to obtain a random string)

SYN Flood是当前最盛行的DoS（拒尽服务进攻）与DDoS（散布式拒尽服务进攻）的方法之一，这是一种利用TCP协议缺点，发送大批伪造的TCP连接请求，从而使得被进攻方资源耗尽（CPU满负荷或内存不足）的进攻方法。(SYN Flood is one of the most popular DoS (refuse to do service attack) and DDoS (Distributed refuse to do service attack), which is a Use the TCP protocol shortcomings, sending a large number of forged TCP connection requests, making the offensive resource exhaustion (CPU full load or memory) Offensive....)

网络重传选择协议，可以检查传输信息的正确性。通过接受方的校检，通知发送方重新发送。 ( Network retransmission protocol, you can check the correctness of the transmission of information. By accepting the prosecution s school to notify the sender to resend.)

说明：  迷宫求解：用二维矩阵表示迷宫，自动生成或者直接输入迷宫的格局，确定迷宫是否能走通，如果能走通，输出行走路线。(Labyrinth Solution: Use two-dimensional matrix to represent the maze, automatically generate or directly input the maze pattern, determine whether the maze can pass, if it can pass, output the walking route.)
