Re: [Haskell-cafe] Writing insertionSort using foldr and a helper function

I can not add more from a teaching standpoint because I can not see what the underlying real problem is. But it seems there's a stack-overflow-question that is connected. http://stackoverflow.com/questions/39710307/how-do-i-write-insertionsort-usi... Please consider including links to existing discussions of a problem in the future. If that question is indeed connected, the down-votes seem to imply you should change your approach. That apparently hasn't happened in the last two days, so I advise trying that. Even if it doesn't help directly, it might bring up new questions that mentors can use as a pivot. Good luck.
