If it is flawed in an interesting way, then I agree that it would be a good learning experience to fix it.   I would suggest to remove such self-made cycle and to learn to use the <algorithm> from standard library. Reinventing own versions of standard algorithms isn't defect itself but the self-made cycles are longer to read so waste time of potential reader, are often less efficient than the ones written by standard library implementer and also contain defects more often than standard library does.   Therefore good companies value specialists who can avoid reinventing standard algorithms.   To find out if your custom sorting algorithm did a good job or not I would suggest to check that sorting result's length is same with original AND then if it is sorted original. Two examples ... A) check that sorting result 'std::is_sorted' and that it 'std::is_permutation' of original ... OR B) check that 'std::sort'ing of original causes sequence that is 'std::equal' with result of custom sorting.   If it matters then B) is likely faster since 'std::is_permutation' has up to quadratic complexity.
