    Gah, I didn't think that one all the way through. Yes it wouldn't be possible to know when you've hit the maximum element for a row so I'll rest my O(n) case.

    I can't believe I oerlooked that. But thinking about it, I think there's still an O(n) solution. You only have to check 2n - 1 elements. Basically taxicab geometry where you start in the top left and...

    There is only one row you'd need to search through as all other rows are guaranteed to have it's maximum value less than it. In the case of equality, it wouldn't matter which of the possible rows...

    The ordo notation gives upper bounds, which means the obvious O(n) solution is also O(n*log(n)). Not sure if I want to point it out though, seems to be an awful lot like "do my homework".

    What makes you think your system uses extended ASCII? In latin1, 'ä' is 228. But why are you worried about the code for the character in the first place?

    Utilizing the upper limit for paths is arguably the easiest way to do it. The PATH_MAX constant, while not standard to C, is quite convenient as it is defined both in Windows in windows.h and in...

    Yeah I can't see the need for anything else than constant memory either. This seems like a classical XY problem where a person has a problem X and though of a solution Y and asks about Y instead of...

    C++ is riddled with things that make it clumsy and a lot less useful. Thinking it has somehow superseded C is just wrong on so many levels.

    There is no /proc/mounts on the machine that requires the program. I found out the mtab on it is /etc/mnttab so I suppose I could just parse that.
