lower bound I have to show that no matter what code you wrote down even code I will never see like just there's just only so much code I could see in my life oh well no matter what you write down it's just not going to work it's just not going to solve the problem fast enough so just from that point of view it seems designing Aram's is easier okay so some of our lower bound says have you have to reason about all possible algorithms right so I assume many of you know about algorithms so I'll spend some time talking more about lower bounds at
