Duck 公司在仓库安装了红外报警装置，如图所示，所有红外线互不相交。n 个发射器和 n 个接收器将平面分成 n + 1 个区域，从左到右分别记作 0、1、…、n。现在技术人员正在进行调试，对于每个点，需要快速知道它处于哪个区域。若正好处于红外线上，则视为处于右边的区域。
Duck company has installed infrared alarm device in the warehouse, as shown in the figure, all infrared rays do not intersect each other. N transmitters and N receivers divide the plane into N + 1 regions, and record them as 0, 1, and n. Now technicians are debugging, and for each point, you need to quickly know which area it is in. If it is on the infrared, it is considered to be in the right area. (2020-05-14, C/C++, 1KB, 下载1次)

先入先出队列，这是一种传统的按序执行方法，先进入的指令先完成并引退，跟着才执行第二条指令。是一种先进先出的数据缓存器，他与普通存储器的区别是没有外部读写地址线，这样使用起来非常简单，但缺点就是只能顺序写入数据，顺序的读出数据，其数据地址由内部读写指针自动加1完成，不能像普通存储器那样可以由地址线决定读取或写入某个指定的地址
First-in, first-out queue, which is a traditional sequential execution method, first enter the command to complete and retire, followed by the second instruction before it is implemented. Is a FIFO data buffer, and he is the difference between ordinary no external memory write address lines, so it is very simple, but the disadvantage is that the order can only write data, read data sequentially, the data address by the internal write pointer is automatically incremented to complete, not like ordinary memory address lines that can be read from or written to a decision to the address specified (2013-06-07, C/C++, 1KB, 下载2次)

在段式虚拟存储器中，虚拟空间中能容纳的程序段数要比主存空间中能存放的相同长度的程序段数要多得多。因此，必然会出现当主存中所有页面都被占用，或者所有主存空间都被占用，而又要从磁盘存储器重调入新页（或新段）的情况。这时，必须从主存储器中淘汰一个不常用的页面（或程序段），以腾出主存空间来存放新调入的页面（或程序段），那么，按照什么样的规则替换主存储器中的页面（或程序段）呢？这就是页面替换算法要解决的问题。

利用哈夫曼编码进行通信可以大大提高通信信道利用率，缩短信息传输时间，降低传输成本。这要求在发送端通过一个编码系统将传输数据预先编码；在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双工传输信息的信道），每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。

This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.
