that doesn't change the time complexity: you're comparing things like
3*1and1*3.Check this out: https://en.m.wikipedia.org/wiki/Computational_complexity_of_mathematical_operations#Matrix_algebra
It's possible to do with lower complexity, but I don't know whether the listed method is considered elegant.
