    Re: How exactly does recursion work with iterators?

    My point was that even if it doesn't make any difference for the logic of my code whether I pass by value or by const reference, C++ still forces me to make a performance consideration when deciding...

    Re: How exactly does recursion work with iterators?

    I used the term "urn" because this problem reminded me of the so called Urn problems I struggled with when studying basic probability theory a long time ago,

    Re: How exactly does recursion work with iterators?

    To pass pair<int> by value throughout the code was an active choice (but maybe I should've motivated it).

    I use this rule of thumb: Pass primitives by value (including anything that doesn't cost...

    Re: How exactly does recursion work with iterators?

    I've cleaned up my solution in #10. It turns out that the second part of the solution strategy isn't necessary. Once it's known how many astronauts there are in an urn it's possible to calculate how...

    Re: How exactly does recursion work with iterators?

    Several of my lambdas aren't strictly necessary. For example also pop_stack() and remove_pair() are both called from one place only. I do this for the reason of abstraction. If I were to tidy up the...

    Re: How exactly does recursion work with iterators?

    I've come up with a solution now according to the strategy in my post #4. The test cases from the problem description work but I would need more to be sure.

    The first part of the algorithm (the...

    Re: How exactly does recursion work with iterators?

    So do I and that's why I'm tempted to give it a go. :)

    I would appreciate if you would post the 70-pairs test case.

    Re: How exactly does recursion work with iterators?

    Without looking at your code, you most likely are changing a data structure while iterating over it.

    This is consistent with your bug description; The code works for smaller cases because then...
