@Mat'sMug I see what you're doing, so you are using LINQ Where to query the source with an operation and put the results into a copy, then iterating the copy and modifying the source separately, right?
Iterators are an easy way to generate a sequence of items, without having to implement IEnumerable<T>/IEnumerator<T> yourself. An iterator is a method that returns an IEnumerable<T> that you can enumerate in a foreach loop.
Here's a simple example:
public IEnumerable<string> GetNames()
{
yi...
That actually sounds a lot like what I'm trying to do^^
I thought IEnumerable was just another type of collection, which would explain why it made no sense to me, now I think I get it
> When the compiler encounters an iterator block, it actually rewrites it to a state machine in a class that implements IEnumerable<T> and IEnumerator<T>. Each yield return statement in the iterator corresponds to a state in that state machine.
@user2296177 Happens to the best of us. One trick to make this easier is to use the "reply" function to link your message to the message you are addressing
it would be nice if yield return played nicely with COM interop.. had to remove all that in Rubberduck, the state machine was causing all kinds of bad things to unmanaged pointers
I kinda like the FP-like style of that, any other FP-like pearls I should know about? (nothing against OOP, but sometimes functions are simpler/more adequate)
the only time I use the query syntax (from x in foo select x.bar) is when I need an intermediate variable (e.g. let bar = x.bar) that the rest of the query needs to reuse.
besides, understanding LINQ means understanding delegates, anonymous types, expression trees, ...there's a wealth of "core C#" knowledge wrapped up in there
I found this code online that helps users batch delete kindle highlights from the Kindle Highlights Page:
(function () {
var buttons = document.getElementsByName("delete");
var n = buttons.length;
for (var i = 0; i < n; i++) {
console.log("Deleting " + i + " of " + n);
buttons[i].click();
}...
I have written a merge sort in Python and C#. Algorithm, which I also have provided, is the same, but codes are slightly different. You can find them in my repository.
Explanation: we have a fixed array of int[n] that can't be mutated. We also have an array of int[k] that can be sorted, and muta...
I am trying to write a solution for a CodeEval problem that converts an integer to words. However, my solution is only 97.5% correct and I cannot figure out why. I've run many of my own test cases and I've always gotten the correct output.

Since it's a working code it might belong to codereview.stackexchange.com but then again, it's such a small piece that does it really need to be shortened? At least you could with specific start values remove the special case of 1. The title also is quite inaccurate. — Sami Kuhmonen40 secs ago
I make too much as a sysadmin to consider changing to a programming job. I also work on too many shiny things to have time to make old shiny things work better
I went to school for it but there was never any jobs so I started with Call Center stuff and somehow ended up here. I miss programming. I do what I can though. Scripting keeps me going.

@Edward Hard alcohol makes me dream, I might have been a shaman in a past life.... std::transform, as its name implies. I was thinking of simply going through a sequence without making any copies where the iterators used internally don't return elements that don't fit a predicate.
