Recent projects used in the need to call the real-name authentication interface, real-name authentication interface price compared to SMS is not a bit higher than a few cents, so that the conditions of the call authentication is strict, so use to JS verify the true name and JS authentication ID number.
Get to the point.
1.js Verify real name
JS Verify the real name, is used to match the Unicode characters, and the Chinese name is generally 2-4, so
This article is about the first step of micro-credit development, public access and Access_token management.
I. Access to micro-credit public number
In the micro-credit Development manual, the section on public number access is more detailed, the document says that access to the public number requires 3 steps, respectively:
1, fill in the server configur
First, is the JavaScript random number function math.random ()
Generate random numbers for a specified range
The Math.random () method has no parameters and returns the number of random numbers between 0~1 if a random between 0~n is to be generated
Number, you can use the following format:
Math.floor (Math.random () *n)
To generate a random

After using Excel to enter the ID number, the bank account and so on the longer number, why becomes has the plus sign and the letter form?
This is a general problem with digital input. The default number format in Excel is "normal", which can display up to 11 digits in a valid number, and more than 11 digi
only one number appears once in a set of data. All other numbers appear in pairs. Please find out the number. (using bit operations)> can understand this: If two numbers are equal, the result of their XOR or after is 0.and 0 is different from any number or is the number itself. (for example, the 00000001^00000001 resul

The maximum number of threads for a single process in a Linux system has its maximum limit Pthread_threads_max
This restriction can be viewed in/usr/include/bits/local_lim.h

The resource of this system is mainly the memory occupied by the thread stac

string as a normal function produces a string (a raw value). As a constructor, an instance of a string object is generated. The latter is rarely used in JavaScript, so basically you can ignore string as a constructor, But be sure to remember that it is a conversion function.

By now you know it. Both +

First class Stirling number S (p,k)
A combinatorial interpretation of S (p,k) is the number of methods that arrange P objects into K-non-empty loops.
Recursive formula for S (p,k): s (p,k) = (p-1) *s (p-1,k) +s (p-1,k-1), 1
Boundary conditions:s (p,0) =0, p>=1 S (p,p) =1, p>=0
Description of recurrence Relationship:
Considering the P item, p can constitute a non-empty loop arrangement, so that the form
