Now that the new ID card has risen from 15 to 18, many software may use the ID card input, the verification work, regarding the new ID card code seems very few articles, I found in 2000 the computer world an article, discovered that now the ID card verification code actually possibly is the English letter x ( In fact, this x is the Roman alphabet, meaning 10, why use the alphabet? Who knows. At least the number key on the phone will not be a new number. (now the method is to use * substitution,

Why is the last digit of my ID card X? In the mandatory national standard gb120043 citizenship numbers, there are clear provisions on citizenship numbers. Currently, there are 18 ID card numbers, each of which has a clear meaning.

M = 1, and the remainder is 0. When m = 2, the remainder of the single digit pair 2 is the remainder. When M = 3, the sum of all digits and the sum of three is the remainder. When M is 4, the remainder of the first two digits is the

So we know that simple four-digit pure digital verification in PHP can be done with Rand (1000,9999), but if we're going to get a random four-digit number of letters and numbers, how do we write a function? The following Hu Peng blog in the PHP data column gives a complete example. "W", "X", "Y", "Z", "A", "B", "C", "D", "E", "F", "G", " H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R",

Original question: For a positive integer n, the digit-sum of n is defined as the sum of n itself and its digits. When Mis the digitsum of N, we call N a generator of M. For example, the digit-sum of 245 is 256 (= 245 + 2 + 4 + 5). Therefore, 245 is a generator of 256.Not surprisingly, some numbers does not has any generators and some numbers has more than oneGenerator. For example, the generators of 216 is

Http://blog.sina.com.cn/s/blog_6a706ff30100sgbb.html What is a four-digit number of points. The quartile, which is statistically, arranges all the values from small to large and divides them into four equal points, with a score of four in the three-point position. The 14th Division (Q1), also known as the "smaller four", is equal to the number of all the values in the sample from small to large after the 25th. The 24th (Q2), also known as the "medi

For a positive integer n, the digit-sum of n is defined as the sum of n itself and its digits. When M was the digitsum of N, we call N Agenerator of M. For example, the digit-sum of 245 is 256 (= 245 + 2 + 4 + 5). Therefore, 245 is a generator of 256. Not surprisingly, some numbers does not has any generators and some numbers has more than one generator. For example, the generators of 216 is 198 and 207. Yo
