One or two binary (original code, anti-code, complement)
The highest bit of binary is the sign bit ("0" represents a positive number, "1" represents a negative number);
There are no unsigned numbers in Java ;
The computer is computed with the complement of integers;
1. Original
Gray code is also an encoding method that can be used for counting. It only changes one bit when adding 1, which simplifies hardware implementation. Therefore, many speed sensors, absolute position sensors and so on will use Gray code count. In addition, due to the characteristics of Ray codes, a change process only changes one bit. Compared with the normal binary
empty, the left subtree of the root node is traversed from the root node, and then the root node is accessed, finally, the right subtree is traversed in the middle order, and the traversal order is CBEGDFA.
Post-sequential binary tree traversal: If the binary tree is empty, it is returned. If the binary tree is not empty, the left-to-right first leaf node access

Method One: The method is very simple, after the RGB color image grayscale, the scanned image of each pixel value, the value is less than 127 The pixel value is set to 0 ( Black ), the pixel valuegreater than or
Use PHP to share binary search algorithm code. Method 1: [binary search requirements]: 1. the sequential storage structure must be used. 2. the values must be sorted by the keyword size. [Advantages and disadvantages] the advantage of the half-lookup method is that the number of times is small. The first method is as follows:

int readbyte = 0; //
int bytestoread = 100; Data buffer size
String fileName = ".. /.. /writexml.xml "; The file to open
This.textBox1.Text = string. Empty;
Open a picture file and use the picture to construct a file stream
FileStream fs = new FileStream (".. /.. /001.jpg ", FileMode.Open);

The first method:
"Two-point lookup Requirements": 1. Sequential storage structure must be used 2. Must be ordered by keyword size.
"Pros and cons" The advantage of binary lookup method is that the number of comparisons is small, the search speed is fast, the average performance is good, the disadvantage is that the unknown Origin table is ordered and the insertion is difficult. Therefore, the binary lookup

Whenever we talk about bits, we usually refer to a certain number of bits. The more bits we have, the more different possibilities we can express;8. In binary, the number of possible encodings is equal to the power of the whole number of 2, and its power exponent is the bit number of bits, and e
