From 1 to 9, the nine digits form a nine-digit number with no duplicates. If a number is extracted from the left, it must be divisible by 1. The number composed of two numbers can be divisible by 2. The number composed of three numbers can be divisible by 3, and so on... The number of each fetch is obtained from the left. Q: What is this number? Returns the numberAlgorithm.

Question: There are 1, 2, 3, 4 digits, can be composed of a number of different and no duplicate number of three digits? How much are they?
1. Procedure analysis: Can fill in the hundred, 10 digits, single-digit digits are 1, 2, 3, 4. Make up all the permutations and then

Function
When we use MSSQL, sometimes the table has a number of full-width digits, but our system can not use them correctly, then we have to replace them with half-width digits. And SQL itself doesn't seem to have this function.
No, we do it ourselves:
The following is a function I wrote myself, of course, my data volume is small, do not consider the performance!
--Convert full-width data into half-widt

Combine the four digits in the middle of the phone number into a Number * and four digits into a number.
MySql APIs have functions:
INSERT (str, pos, len, newstr)
Returns the str string. Its substring starts from the pos position and is long replaced by the string newstr. If the pos length exceeds the string length, the return value is the original string. If len is longer than other strings, it

Php implementation of adding 0 complement before formatting digits with less digits
Php format the number. when the number of digits is insufficient, add 0 to complement it. This article provides two implementation methods, sprintf and number_format, respectively. If you need it, come and have a look.Example of formatting a number in php.

In C + + programming, sometimes ask us to keep the data after the decimal point, or how many digits to retain the number of valid numbers and so on, then we need to use the setiosflags and setprecision functions, remember to include the header file #include #include #include//need thisusing namespacestd;intMain () {floatA =4, B =3, C =2; coutEndl; coutEndl; cout3) Endl; cout3) Endl; coutfixed) 3) Endl; coutfixed) 3) Endl; return 0;}The output is:1.333
