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

The Linux kernel is written in C, but the Linux kernel is not called an operating system, and the kernel only provides basic device drivers, file management, resource management, and so on. Is the core component of the Linux operating system, the Linux kernel can be widely shifted, and also applicable to a variety of hardware.The Linux kernel version has both stable and development versions. The Linux kernel version number typically consists of three-bit numbers, such as the 2.6.18 kernel versio

/* Print out all the "Narcissus number", the so-called "Narcissus number" refers to a three-digit, its members of the digital cubic and equal to the number itself. For example: 153 is a "narcissus number", because of the three of the 153=1 +5 of the three square +3 of three times because of 100 200 300 500 400 The whole hundred is not a narcissus can be directly excluded and 101 is not the basis of the Narcissus can be directly excluded from these two

To convert a number to a 16-digit string, we can call sprintf, but the standard library of C does not provide a function that converts a hexadecimal string number to an integer number. I've written a feature that can be implemented and optimized as much as possible.

This article mainly introduces how to generate a unique number in PHP. in this article, convert the hexadecimal value to 36 to obtain more than 60 million unique numbers that are not repeated, with the number of digits being 10 digits, if you need a large data number, you can refer to the following, for example, the five-digit license plate number, the ten-digit license number, the order serial number, and
