Char (n) is a fixed-length format. The field in the format of char (n) occupies a fixed width of n characters. If the actual length of the stored data exceeds n, the excess data is truncated, if the length is less than n, it will be filled with null characters. Varchar (

Idea: Preliminary view it is difficult to analyze the meaning of the expression at a glance, we might like to analyze the example, assuming that n = 5, the binary is represented as 101, then n-1 = 4, the binary is expressed as, 5 4 = 101 100 = 100 = 4! = 0, let's look at more examples below5 4 101 - 4 6 5 the 101 4 7 6 111 the 6 8 7 + 0111 0We will find that to make the expression equal to 0,

I. background of the Byzantine issue I will not describe algorithms directly here: The following is taken from Lamport's paper: Note the following for this algorithm: (1) In the first round, the general will send the message to all the deputy officers, and the I-th deputy officer will receive the message as Vi. For example, 1 (Attack) (2) In the second round, Li (the I-th deputy officer) will doubt whether the message Vi sent by the General is correct or wrong, so he will ask the remaining depu

Using formula (n-1) 3=N3-3n2+ 3n-1 Set S3 =13+ 23+ 33+ 43+... + N3 And S2 =12+ 22+ 32+ 42+... + N2 And S1 = 1 + 2 + 3 + 4 +... + n D: S3-3S2 + 3s1-n = (1-1) 3+(2-1) 3 +(3-1) 3+ (4-1) 3+... +(N-1) 3= S3-N3 Therefore, 3S2 = 3s1 + N3-N Bring S1 =

Question: programming, input two integers n and m, from the series 1, 2, 3 ,...... N is random, so that the sum is equal to M. All possible combinations are required. Analysis: the idea of sub-governance. You can split the problem (m, n) into (m-N, N-1) and (m,

integer n-th square Suppose an integer is 10, and how to solve the 10 of the 75-way quickest.1.75 binary number in the form of 10010112.10 of 75 Square =10^64x10^8x10^2x10^1 In this process, we first find out the 10^1, and then according to the 10^2, and then according to 10^2 to find out 10^4, ..., finally, according to 10^32 to find out 10^64, that is, 75 of the binary number form a total number of bits, we will be on the original basis of the squa

Description of the meaning of N and M in MySQL Data Type DECIMAL (N, M), mysqldecimal My colleague asked me what the meaning of N and M in the MySQL Data Type DECIMAL (N, M). Needless to say, M is obviously the DECIMAL place, but is N the maximum number of digits before the

Explore n in char/varchar (n): number of characters or bytes, number of varchar bytes [Problem source] When I display the database table designed, yu asked me, why is the top_info field of your top_info defined type varchar (100) 100, how many Chinese characters can be stored in the length of 100? At that time, the idea was that there was a correlation between how much text can be stored in this 100 databas
