I have question about 4:21 about drawing recursion tree. I always draw them like for each node, calculating the work done in this node. (as shown in Introduction to Algorithms 4th Leiserson Stein Rivest Cormen MIT Press p. 96) using this approach the recursion tree drawn should be n ---> cn, n-1--->c(n-1), n-2 ---> c(n-2), ... 1 ---> 1 but you draw it slightly different. I guess both approach gives the correct results for the example in p. 96 but i am not sure. Can you explain it a bit further?

at 11.46 you have mentioned the depth of the tree i.e log n to the base (10/9). can you please explain how you are calculating this depth?
@vivekmishra0073 жыл бұрын
@Prasanna Sasne In the case when the array is divided into 1/10 and 9/10 of the total size we have to consider the part of the recursion tree with the maximum height, the tree one part is getting divided by 10 and another part by 10/9 so as 10/9

You cannot say that Quick Sort's time complexity is Big-oh of nlogn because it's not. Big-oh represent it's worst case and the worst case time complexity of quick sort is O(n²). To represent the average case you should use Big-Omega which is another symbol: Ω(n log n). Try not to explain difficult subjects to other people if you are not sure about it, it's hard to understand it and it gets even harder if many people say different things about it.
@redkai113 жыл бұрын
That is common misconception. Big-o does not represent its worst case and big-omega does not represent average case. Big-o is just the upper bound and big-omega is just the lower bound of time complexity. For worst case, quicksort is actually theta(n^2) so it is completely valid to say quicksort's time complexity is O(n^2) when we are considering the worst case. For best case, quicksort's time complexity is theta(nlog(n)) so it is, again, completely valid to say o(nlog(n)) or big-omega(nlog(n)).

@@uberboy6986 at this point, I am convinced that you don't know what theta is and its relation to big-o and big-omega. maybe try digging into google more and you will find that anything of theta(f(x)) is also O(f(x)) and big-omega(f(x))
