Who said anything about witholding them?
Give a man a fish and all that, instead of doing a quick brain dump of the solved problem one can also explain the reasoning behind one's solution.

Here you could have explained why you can never remember between permutations, combinations, then maybe give a bit of math background regarding the number of permutations/combinations for n numbers and then explain how you came up with that answer

If you have the time; the need; and the arrogance to believe that it is your role to force your brand of fish down the OPs throat; feel free, have at it. I won't stop you.

But nor will I require it of you.

I prefer to believe that if the OP is actually interested in the math or its derivation, then having been shown that 'permutations' is the algorithm of choice for solving his problem, he will probably be perfectly able to go off and look up both the math and algorithms for himself. After all, he found this place to ask his question didn't he.

Alternatively, if he simply isn't interested, I haven't wasted my time coming up with my explanation -- which would non-authoritative, and probably imperfect -- only for him to ignore it; whilst others pick holes in it and I then have to defend it.

If the OP chooses to use my code, he will have to install Algorithm::Combinatorics; and that already contains a shitload of information and further reading that is far more authoritative and thorough than anything I have the time to construct.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)
In the absence of evidence, opinion is indistinguishable from prejudice.

And again you assume.
First you assume about forcing. Why do we have "readmore" tags? maybe so we do not force people to read through / load large swath of code/speech.
Second you assume that one can only offer unrequested help out of arrogance.
Either you believe everyone else has this kind of attitude toward helping others and then your world view must be quite bleak or you are just projecting your own behavior onto others, assuming they think like you.

Even if your understanding is not perfect and your time limited, a short explanation and maybe a link to more reliable sources is better than nothing.

TL;DR People could benefit more from your skills if you gave even the shortest explanation.

Please stop trying to put words in my mouth.

And again you assume.

No I didn't. (You should look up the meaning of "assume".) I read what you wrote and drew the (only) logical implications from it.

More clearly stated. I am not assuming your arrogance; I am stating that your presumptions ARE ARROGANT.

If you believe that everyman will benefit from you "teaching them your brand of fishing"; be my guest.

But do not seek to impose your arrogant presumptions upon me.

TL;DR. I'll allow you to answer questions in your way; and I'll thank you to allow me to answer them in mine.
