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...
It's not clear where this stack trace comes from (either from an exception or the current thread), but it doesn't matter, the way to do it is the same. Both Exception's and Thread's have the getSt...
The other answer already provides the more straighforward solution (push with --delete option). But there's an older syntax that also works: git push <remote-name> :<branch-name> N...
The solution proposed by the other answer works, but there's a corner case. If the last message is shorter than the previous one, you might not get what you want. Example: print("this is some text...
How do I clone the repository with only part of the history? It depends on what part you want. It's possible to have shallow clones (which is exactly what you need, only a part of the commit h...
I can't speak for the people who designed it, but I guess it was made this way because you can merge multiple branches all at once. Let's say I've created multiple branches: C---D => ...
There are many ways to do it, it depends on what data you already have and/or the Java version. I have only the year's numeric value If you already have a value as a number (int or long), and i...
How to verify if a year is leap? Given a numeric value (such as 2023) or some object that represents a date (such as Date, Calendar, LocalDate, etc), how can I do it?
I wouldn't use grep. As the other answers already said, it's not the right tool for this job. Considering your specific case (fields separated by /), basename is the most straighforward way, as st...
Given the link where the code comes from (based on your other question), this is just a, let's say, "free-form/pseudo-code/documentation example". It's not a valid JavaScript code. It's more like...
I personally think its syntax is confusing. Well, it's just a matter of getting used to it, I guess :-) Anyway, this code is just looping through all childNodes and in each iteration it cal...
How this recursive treewalker works? To understand what the code does, we need to first see what problem it's trying to solve and why it needs to be solved this way. Let's consider this HTML:...
Yes, it's possible. In a more general way, every recursive algorithm can be converted to an iterative one (and vice-versa). You just need to use a stack. Internally, a recursive function will use...
Does a for...of loop must contain a variable without assignment sign (=) Yes. and why? Because that's the syntax defined by the language specification. The people who defined it decided ...
any DOM "tree" node is actually a "branch" Not exactly. Document Object Model and Nodes According to the MDN documentation, the DOM (Document Object Model) is "the data representation of the...
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're getting close, just need a few adjustments. Instead of using the hostname property, I prefer to use host, because it also includes the port (in case the URL has one) - check the documentati...
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 ...
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...
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...
I've created a function that calls scanf passing a void pointer as argument: void read(const char *format, void *p) { scanf(format, p); } And tested it with different types: int n; read...
PS: for small arrays and/or if the function is fast and doesn't cause performance bottlenecks, none of the below is really necessary (see the analysis in the end). That said, let's see how to sol...
When using the Array.prototype.sort method, we can pass a compare function as argument. Then, this function can be used to process array's elements, so the comparison is made using some custom crit...
Why object-oriented instead of class-oriented? tl;dr Because you can "do OOP" without classes. Long answer A class is one possible way to implement object oriented programming. But it's n...
By "deeply clone", I assume you mean "also make copies of whatever nested structures the object might have". And for those, I guess libraries like Lodash are more reliable and appropriate if you wa...
