@jason,i am understanding all the things ,you are sayng but .just tell me this-"
"Means , the root works θ(nc) and the children especially the Leaves work Θ(nlogba)."
the recurrence is T(n) = a T(nb) + θ(nc) which means n is divided into n/b at each level.right?and at each level nc work is done..right?so how is that leaves do more or less work?overall work at all the levls will be same.right??
and pls dun call me ma'am..i am also a student like you..;):-P
