Usage:Width:calc (100%-(20px + 2px) * 2); /* Use 100% minus two 20px padding and 2px border*/For Calc (), summarize the following points:1. Compatibility: In ie9+, ff4.0+, chrome19+, safari6+ support is good, mobile side support is not ideal;2. The expression supports addition, subtraction, multiplication and subtraction, and also supports mixed use of units (%, px, EM, etc.);2. In the expression, there must be a space before and after the "+", "-" o

The benefits of the Less needless to say, everyone knows that it does not hurt to write CSS, and I did find some problems when I joined Calc recently in less, which I wrote in less: Div { width:calc (100%-30px); The result less this as an expression, and the result is resolved to me as follows: Div { width:calc (70%); } So, I rewrite less to this: Div { width:calc (~ "100%-30px"); } The parse result is normal: Div { width:calc (100%-30px);

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

Function: Upgrade the ID card number of 15 to 18 characters (according to GB 11643-1999) Parameter: original number (15 digits) Return Value: the 18-digit number after the upgrade.

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

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

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
