Re: [algogeeks] Re: content extraction
+1 Dan. I've been seeing lots of vague questions around. I thought of doing the same but for the sake of peace I decided not to troll this one. I'm not saying its OP's case but many people either think the job of answering questions is costless or maybe think it's our duty to do so. If you need help at least help us to help you.

Re: [algogeeks] subset of an array
is it a contiguous set, any sparse subset or what? if it's a subset of a set then it can be sparse, but when you say array you make it quite tricky to figure out. with all due respect sir, please mind that when you make a question you're taking peoples time to answer it therefore if the answer is useless to you you'd have wasted someone else's time with no reason. so please, I gently ask you to make a clear question next time.

Re: [algogeeks] puzzle
and why is that related to algorithms anyway? from [1] To further highlight the difference between a problem and an instance, consider the following instance of the decision version of the traveling salesman problem: Is there a route of length at most 2000 kilometres passing through all of Germany's 15 largest cities? The answer to this particular problem instance is of little use for solving other instances of the problem, such as asking for a round trip through all sites in Milan whose total length is at most 10 km.

Re: [algogeeks] is it possible??
in code bellow you declare main because any executable needs an
entrypoint you cannot fake that
anyway, it doesn't use main at all to invoke those functions.

Re: [algogeeks] Deletion in Vector
yes they are shifted that's why you should use std::deque whenever that matters http://www.cplusplus.com/reference/stl/vector/erase/ Because vectors keep an array format, erasing on positions other than the vector end also moves all the elements after the segment erased to their new positions, which may not be a method as efficient as erasing in other kinds of sequence containers (deque, list).
