Thank You
Great work no here and there, to the point... very Helpfull... please make more videos over Automata /compiler /network please....
Thank you :) We will soon upload videos on computer network.
very helpful .....mam CN mcq ki series start kro na plz
Yes will do very soon
Mam in ques u hv taken from gate 2014 containing statements S1 and S2 ...in S2 AB--C is essential FD in cover as it is not determing all the attributes of relation ....but u hv said it will be not be included in cover
Hey Manu, in S2, AB -> C is not an essential FD as we can infer it from AB -> E and E -> C (Transitivity rule). That is why, we will not include it in our cover. Sometimes we may not be able to decide which one is essential. There you can use method described in previous question to find canonical cover (by taking two closures of AB with and without including FD AB->C).
And regarding video quality, we have checked and found that it may take few hours to get 144p resolution. so whenever you find higher quality, just wait for few hours as youtube may take some time to get all resolutions.
