reverse

For example: My string is: 123456789 nn nn oo nn nn mlm nn203 . My target is: nn . Then, I match string from the end to the beginning and return the first match result and its postion. In this examlpe, the result is nn start in [-5] end in [-3]. I wrote the simple funcitonto do this process, but how to use regular expressions to do this job? For the string itself, just do a findall and use the last one: import re st='123456 nn1 nn2 nn3 nn4 mlm nn5 mlm' print re.findall(r'(nn\d+)',st)[-1] Prints nn5 You can also do the same thing using finditer which makes it easier finding the relevant indexes

Is it possible to reverse a pseudo random number generator? For example, take an array of generated numbers and get the original seed. If so, how would this be implemented? Jonathan Basile This is absolutely possible - you just have to create a PRNG which suits your purposes. It depends on exactly what you need to accomplish - I'd be happy to offer more advice if you describe your situation in more detail. For general background, here are some resources for inverting a Linear Congruential Generator: Reversible pseudo-random sequence generator pseudo random distribution which guarantees all

I am trying to reverse an array in 2 ways: 1) By creating a new array which was very easy: public static int[] reverse(int[] array) { int[] reverseArray = new int[array.length]; for(int i = 0; i < reverseArray.length; i++) { reverseArray[i] = array[array.length - i - 1]; } return reverseArray; } 2) The second method I got my answer but I actually don't understand it very well, it actually makes use of swapping, giving the value of the array to a temporary variable then changes it and returns it to the original variable: public static int[] reverse2(int[] array) { for (int i=0; i < array.length

Following REST it is advisable that API is discoverable and should be interlinked. Does ServiceStack support any kind of reverse routing? I'm looking for something like Url.RouteLink in ASP MVC. There's some mixed concepts stated here. In and effort of trying to comply with REST you wish to embed URI's in your responses. How best to achieve embedding URI's in your responses. You've assumed a "Reverse Routing" mechanism is how this should be done. REST style vs Strong-typing I want to be explicitly mention here that one doesn't imply the other. On the one hand you're looking to follow a REST

I am trying to reverse proxy my website and modify the content. To do so, I compiled nginx with sub_filter. It now accepts the sub_filter directive, but it does not work somehow. server { listen 8080; server_name www.xxx.com; access_log /var/log/nginx/www.goparts.access.log main; error_log /var/log/nginx/www.goparts.error.log; root /usr/share/nginx/html; index index.html index.htm; ## send request back to apache1 ## location / { sub_filter <title> '<title>test</title>'; sub_filter_once on; proxy_pass http://www.google.fr; proxy_next_upstream error timeout invalid_header http_500 http_502 http
