find nine digit zip code

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

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

of analysis is the same. From this we can conclude that we want a function (that is, the SetAll () of the following code) to figure out the total number of probabilities that are smaller than the current number, and then add up to +1 is the desired result, see Code implementation: // Function function: get each bit, if it is another number, the total number of possibilities is smaller than the cu

Transferred from: http://blog.csdn.net/yudandan10/article/details/11878421Computer composition of the Hamming check code, I believe that the learning will have to understand, then the verification of the determination of the bit, I think some people are not very clear, today I would like to detail how to determine the check bit to shareFirst look at the basic concepts:2^r≥k+r+1where r is the check bit, K is the information bit information bit is known

Image processing is a very wide-spread technology, and Python, which has a very rich third-party expansion library, will certainly not miss this feast. PIL (Python Imaging library) is the most commonly used image processing library in Python, and if you are python2.x, you can download it at the following address: http://www.pythonware.com/products/pil/ Index.htm, to find the corresponding version to download it.Note: The PIL module has been replaced i

Yesterday, when using JS to the foreground floating-point number to find that: 0.05+1.08=1.1300000000000001 Check on the Internet there is indeed such a bug, in addition to the number of digits on the control there is no good way (hope that experts can put forward Other ideas). So I write a control of the decimal number of the JS method to solve the development of the immediate Copy Code

PHP executes the zip and rar decompression methods first. it will be used for further research. Zip: PclZip http://www.phpconcept.net/pclzip/index.en.php Rar: PECL rar http://pecl.php.net/package/rar In the past, we had to execute the decompression program in php. The most common method was to write the command and run it using the execute function such as exec (). This may work in Windows, but changing to
