The process of checking errors using CRC can be simply described as follows: the sender follows certain rules based on the K-bit binary code sequence to be transmittedGenerates an R-bit supervision code (CRC Code) for verification, which is attached

Daily question: the third variable is not applicable and two input parameters are exchanged. Problem description: Write a function swap and input two parameters A and B. The third variable cannot be used in the function, and the and B after

Several bit operations: >>: Shift right (the direction of the arrow), discard the removal of the low position, and add the high position to the symbol bit (if it is a positive number, add 0, if it is a negative number, Add 1 ). >>>: The

PrefaceI noticed that some people are confused about bitwise operations, so I decided to write this simple tutorial to illustrate how bitwise operations are performed. Bit IntroductionBit. What is it? You may ask. In short, the bit is 1 and 0,

How does delphi use basic drawing functions to draw statistical charts? A drawing tool that comes with Windows cannot meet our drawing needs in any way. Many effects need to be implemented in other tools. How are these advanced functions

Question State compression Dynamic Planning (DP) is a dynamic planning that uses binary numbers to represent states. We often use 1 in binary to select the State represented by this bit, and 0 to indicate the opposite meaning. For example, if there
