JS implements the last digit when the ID card number is 15 to 18 charactersAlgorithm According to the provisions on the national identity number in the National Standard GB 11643-1999 of the People's Republic of China, the national identity number is a characteristic combination code consisting of a 17-digit digital ontology code and a digital verification code. The order is from left to right: six-

Now we use all 18-digit ID card numbers, and the previous 15-digit ID card numbers. How can we convert a 15-digit ID card number to an 18-digit ID card number? 1. First, after 6th digits of the 15-digit ID card, "19" is changed to 17 digits, that is, the Year of birth plus 1

ID number 15, 18 digits. ID 18-bit authentication The 18-digit ID standard is clearly stipulated in the gb11643-1999 "citizenship number", which was implemented by the National Quality and Technical Supervision Bureau on July 1, 1999. Gb11643-1999 's "Citizenship number" is a revised version of gb11643-1989 's social Security number, which states that the original standard name "Social Security Number" is renamed "Civil Status Number", and that the "C

100000a+b;The new number after displacement can be expressed as 10b+aEstablishing an equation relationship: 10b+a=nx (100000a+b)by discussion, N = 2, 4, 5, 6 are not available.N when and only if equals 3 equation can be changed: 10b+a=3x (100000A+B)7b=2999999ab=42857aAfter discussion, A can only take 1, b get 42857The original number is: 142857 will move 142857 respectively 1-bit, 2-bit, 3-bit, 4-bit, 5-bit, the new number obtained is not difficult to find their multiple relationship with the o

Question: For multiple groups of data, each group calculates the N number containing '123' (cannot be disconnected), for example, 1: 666, 2: 1666,14: 666. Question: I didn't think about the AC automatic solution, but I didn't know the digital DP. Here there is a digital tree similar to the digital DP, but it is different from the digital DP. Digital tree: Splits the number N into multiple segments like a line segment tree and performs recursive processing to obtain the answer. Details(LUE)Soluti

Recently, when I was working as a health bureau examination network, I needed to implement the function of sending a verification code via SMS. Therefore, I had to use the function of randomly generating 6-digit verification codes, write a random int i=(int)(Math.random()*1000000+100000); String messageCode = String.valueOf(i); After the test was sent, a 6-digit random number was sent, and thought it was co

Python3 digit Number (6), python3 digit number The Python numeric data type is used to store numeric values. The data type cannot be changed, which means that if you change the value of the numeric data type, the memory space will be re-allocated. The Number object will be created when the following instances assign values to variables: 1 var1 = 12 var2 = 10 You can also use the del statement to delete some

Find the nth digit of the infinite integer sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ... Note:N is positive and would fit within the range of a 32-bit signed integer (n Example 1: Input:3 Output:3Example 2: Input:11 Output:0 Explanation:The 11th digit of the sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, one, one, ... is a 0, which are part of the number 10. Here are the practices of C + + We first analyze the rela

Using temporary variables is very simple#include int main (){int a = 1, b = 2, c = 0;printf ("a=");scanf ("%d", a);printf ("b=");scanf ("%d", b);c = A;A = b;b = C;printf ("a=%d,b=%d\n", A, b);System ("pause");return 0;}At this point, I thought I could do the same without adding temporary variables.The method of adding and reducing can be used#include int main (){int a = 1, b = 2;printf ("a=");scanf ("%d", a);printf ("b=");scanf ("%d", b);A = a + B;b = a A;A = a-B;printf ("a=%d,b=%d\n", A, b);Sys
