Why you put this topic here?

Re: Two Sorted Array, merge them
The code is to merge two sorted array. Anything wrong here?

Re: Two Sorted Array, merge them
I mean most questions in this folder are knowledgebased questions. Then there's one algorithm question, looks strange.
Anyway, I think there should be some folders for algorithm, I have "Sorting" (which you already have), "recursive", "dynamic programming", "bit operation", "binary search", "random algorithm" and "other algorithm" on my computer. I hope you could also create these forums.

Re: Two Sorted Array, merge them
I already created some topics as what you listed. By the way, what is random algorithm?

Re: Two Sorted Array, merge them
Random algorithm is the name I gave It includes the algorithms that deal with randomness, which includes the classic algorithms: FisherYates shuffle, reservoir sampling, and some others.
