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. 1. string

The problem is divided into two parts, preferably with only two pointers.For example, a pointer can be swept back from the head, and the other pointer is swept forward, ensuring that the first pointer always points to an odd number, the last pointer always points to an even number, and then the two are exchanged until the final two pointers are equal, that is, all the elements are scanned.The code looks like this:1 //Adjust the array order so that the odd di
