Let's suppose
splitNis equal tocurr.size(), and size ofvector<int> testis alwayscurr.size() - 1(value from1 to size-1, and index from0 to size-2).Then the
i-for-loopwill produce a indexsplitN - 1, akasize-1as the last item, which will excceed the bounds ofvector<int> test.Accessing
test[i]will be undefined behavior and will return unexpected value(e.g. 268435456). This would causejandititerates within a huge range.Actually no memory issues but really costs CPU and wastes time.
