Question
Refine the mathematical model to better explain the experimental results in the table given in the text. Specifically, show that the average number
of compares for a successful search in a tree built from random keys approaches the
limit 2 ln N 2
– 3 1.39 lg N – 1.85 as N increases, where
.57721... is Euler’s
constant. Hint : Referring to the quicksort analysis in Section 2.3, use the fact that the
integral of 1/x approaches ln N
.
