members, to meet the requirements of the deletion of comments, so, SortedSet is most suitable here (time complexity O (log (N))).
So, the data types I need to use are sortset and hash,sortset for paging, and hash is used to store specific key-value pairs of data, and I've drawn the following chart:
In the sortset structure of the diagram above, the topicid of each topic is used as the key of the set, and the CreateDate and Commentid of the comments associated with the subject are respectively
verify the data sent this, in the receiver we use the data received by using "mode two division" divided by the use of polynomial, if the remainder of 0 indicates that there is no error in the transmission process, if not 0 indicates that there are errors in the transmission.
Step1: Confirm the use of polynomials, usually we will adopt a fixed polynomial, common several kinds of generating polynomials such as:
Crc8=x8+x5+x4+x0
Crc-ccitt=x16+x12+x5+x0
Crc16=x16+x15+x2+x0
Crc12=x12+x11+x3+x2+x0

test and set command BTS, bit test and reset instruction BTR, bit test and take the counter-instruction BTC, bit forward scan instruction BSF, bit backward scan instruction BSR, etc. Conditional setting directives this is not a specific instruction, but rather a command cluster, which includes approximately 30 instructions for setting a 8-bit register or memory operand based on some bit states of the EFlags register. Like Sete/setne/setge and so on.

1. The reserved characters of Erlang include:
After and andalso band begin bnot Bor bsl bsr bxor case catch cond Div end fun if let not of or orelse query receive REM try when XOR
These are basically symbols used for logical operations, bit operations, and special expressions.
2. The types of Erlang include:1) binary, used to indicate an unknown memory areaFor example:1> 2>
# Pragma idata and # pragma udata in PIC:
Idata indicates the initialized data. Udata indicates that no data is initialized.
When a data block does not have enough space to store a continuous data (array), # pragma idata or # pragma udata can be used to define a new region for storing data blocks. However, # pragma idata or # pragma udata application space is still limited. Generally, it cannot exceed 256. If it exceeds, it can only be done with another idea.
Why cannot it be greater than 256?

This plan has been running for a long time. I want to build a single-user Blog system and plan to use VS2003. As a result, I watched a video showing the new features of VS2005 in a few days, we decided to port the original project to the ASPNET2.0 environment.
Some time ago, I finally had the freedom to take control of myself. I always browsed around the Internet and admired others' project works and development documents. start from today, or BSR.
