Can that even be done without having to repeat either or resorting to more advanced processing than pure regular expressions I don't think it can. If you don't want to repeat x1=y2 and c5=d6, you...
Yesterday I answered this question. This morning, when I visited site, the question has disappeared, so my guess is that it was deleted. But now I saw that it was undeleted (I initially thought t...
I've tried to post a comment in this question, and when I clicked in "Post" button, I've got this error message: 500 Internal Server Error If you are the administrator of this website, then ple...
Currently, Java 16 is the latest version, and there's no support to branch reset yet. But one - still far from ideal - alternative is to use lookarounds: Pattern pattern = Pattern.compile("([aeiou...
I've seen that recently two requests to add syntax highlight to some languages were deferred (this and this). According to the status-deferred tag description: "the requested feature will not be i...
As you're using userscripts, I'm assuming this code is supposed to run in a browser. Hence, you could download the scripts and add its contents to the page's DOM (by using a script element). For t...
Caesar Cipher originally deals only with letters (ASCII "A" to "Z", without diacritics/accents), so I'm not sure why you included ۤ$%& in your answer. And using indexOf (as you did) is not ver...
Some comments and your answer are doing this: document.body.innerHTML = document.body.innerHTML.replace(/x/g, '*'); But as explained in the comments, this is not a good solution, because it can...
You could use fgets to read from STDIN. And to print the message, just use the short tag (<?= whatever, which is a shorthand to <?php echo whatever; ?>): <?='Hello, '.fgets(STDIN).'!'...
It depends. Regarding "grouping functions/methods": as a general rule, you should group things that make sense to be together. Yes, it's a very broad and generic rule, and somewhat subjective. How...
According to the documentation, the hasAttribute method expects only one argument (the attribute's name), and it tells only if that attribute is present, regardless of its value. Hence, the return ...
You could create a dictionary to map each attribute to its respective list of items. Then you get the dictionary values to create the final list. Something like this: import re pattern = re.comp...
Based on your answer, I guess you just wanted to have a list of unique arguments that were passed to B::add. In that case, you could use a Set instead of a List: // "Type" is whatever type B:add r...
As mentioned in another answer, when you have code such as if (someVar), you're subject to truthiness. To be more precise, this code will run under the rules of Boolean coercion. In JavaScript, wh...
