In Java, Byte uses a binary representation of 8 bits, and we know that each character of the 16 binary needs to be represented by a 4-bit bits (23 + 22 + 21 + 20 = 15), so we can convert each byte to two corresponding 16 characters, That is, the high 4-bit and low 4 bits of byte are converted to the corresponding 16-character H and L, and combined to get the resu

I. Problem Description
For 16-color (4-bit) images, VGA uses a bit plane, while Dib uses a linear approach. No matter which method is used, complicated bit splitting operations are required when accessing a single pixel, making it dif
The original objective of Unicode is to use a 16-bit encoding to provide ing for over 65000 characters. However, this is not enough. It cannot cover all historical texts or solve the implantation head-ache problem, especially in network-based applications. The existing software must do a lot of work to program 16-bit data. Therefore, Unicode uses three encoding methods with some basic reserved characters. T
The structure of the classic convolutional neural network generally satisfies the following expressions:
Output layer, (convolutional layer +--pooling layer?) ) +-Full connection layer +
In the above formula, "+" means one or more, "? "represents one or 0, such as" convolutional layer + ", which represents one or more convolutional layers," pooling layer? " "represents one or 0 pooled layers. "--" indicates the forward direction.

When the protocol is resolved. Always encounter a variety of data conversion problems, from binary to Decimal, from byte string to integer, etc.Not much nonsense on. Directly on the sampleBinary conversions between integers:
10-in-turn 16-in: Hex (==>) 0x10
16-in-turn 10-in: Int (' 0x10 ', +) ==> 16

In programming, these three character encoding formats are often converted to each other, so that many third-party libraries fail to call for unknown reasons, in fact, many are because third-party libraries support UTF-8 rather than Windows Default support of the UTF-16 caused.

Unicode is commonly known as unified code, universal code, single code, standard universal code.
Unicode development is under the responsibility of the non-profit organization unified code Alliance, which is committed to replacing the existing character encoding scheme with the Unicode scheme. Because some solutions often have only limited space and are not applicable to multilingual environments.
Unicode is recognized and widely used in the internationalization and localization of computer soft

Basic algorithm: Using complement, simulate the second mechanism subtraction (additive similarity), the difference (complement) is converted to the original code, and then converted to hexadecimal and output.
