InputStream and OutputStream are the input and output streams in a byte stream.

question: How to get the median number in a data stream. If you read an unusually number of values from a data stream, the median is the number in the middle after all the values are sorted. If an even number of values is read in the stream, the median is the average of two digits in the middle after all the values are sorted.

The IO stream in Java is divided into byte stream and character stream, and each stream also divides the input stream and the output stream.Let's start with the input and output streams: the input and output are for program memory, so the input is to write data to the memory
BYTE streamIn the I/O class library, Java.io.InputStream and java.io.OutputStream represent byte input streams and byte output streams, which are abstract classes that cannot be instantiated, and the smallest unit in the data flow is bytes, so it is called a byte stream.The method of reading data in InputStream is as follows:1, int read ()Function: Reads a byte of data, and returns the read data, and if 1 is returned, it reads to the end of the input stream
byte stream :A FileOutputStream (file name) creates a file output stream that outputs data to the specified file object.B FileOutputStream (filedescriptor) creates a file output stream that outputs data to the specified file descriptor.C FileOutputStream (String name) creates a file output stream that outputs data to a
Streaming Transmission is widely defined. It is a general term for the technology that transfers media (such as videos and audios) over the network. Its specific meaning is to transmit video programs to PCs over the Internet. There are two methods to implement stream transmission: realtime streaming and progressive streaming ). (Baidu encyclopedia)
Currently, audio/video (A/V) and other multimedia information are transmitted over the network in two wa
1. What is a streamThe stream in Java is an abstraction of a sequence of bytes, and we can imagine a water pipe, except that it is no longer the water that flows in the pipe, but the sequence of bytes. Like currents, streams in Java also have a "flow direction," where an object that is typically read into a sequence of bytes is called an input stream, and an object to which a sequence of bytes can be writte

InputThere are one or more test cases in the input. each case starts with a line giving two integers n and m, where N is the number of rows of the map, and m is the number of columns. the rest of the input will be n lines describing the map. you may assume both N and m are between 2 and 100, aggressive. there will be the same number of 'H's and 'M' s on the map; and there will be at most 100 houses. input will terminate with 0 0 for N and M.
OutputFor each test case, output
will be followed by a line containing zero.
OutputFor each test case, output a single integer on a line by itself-the number of seconds you and your friend need between the time he leaves the jail cell and the time both of you board the train. (assume that you do not need to wait for the train-they leave every second .) if there is no solution, print "back to jail ".

Although the question is for the maximum cost, we can convert it into the minimum cost. Use the difference between a number greater than the maximum value and each number as the cost value. After the final processing, I can do it. Some people simply multiply each value by-1, which is easier.
I have been thinking about this question for a long time and asked some people. Finally, some knowledge is obtained.
