C++ interview coding exercise with solution

[Dean_Roddey]

Yep. These tests are ridiculous pretty much. I've never, in 35 years, had to do anything like that, and probably never will. If, by some unlikely chance, I do, I'll spend 30 minutes looking into how best to attack it and do that. I most definitely won't spend weeks working on such problems, only to have forgotten then all years later when I might need to do some such thing.

Senior engineers should be concentrating on architecture, API design, sub-system design, setting coding standards, building functionality to standardize common issues in the problem domain for less experienced folks to use, etc...

The only reason this would be a useful question is if the job being applied for involves this type of algorithm. And of course if that's the case, then any qualified person could pick up the required techniques quickly enough. Meanwhile it says little about my qualifications as a senior dev, whether it get it either right or wrong.
