Let f(n) be the average number of full nodes in an n-node binary search tree.
a. determine the values of f(0) and f(1).
b. show that for n > 1
f(n)=n−2 /n +1/ n (sum n−1 i=0(f(i)+f(n−i−1)) start at i = 0 end at n-1 for the summation
c. show (by induction) that f(n)=(n−2)/3 is a solution to the equation in part (b), with the initial conditions in part (a).
d. use the results of exercise 4.6 to determine the average number of leaves in an n-node binary search tree.

Install and use wireshark program ( send back screen shots and other vital information) case project 3-2: decode a tcp segment in a wireshark capture in this chapter, you walked through tcp segment to interpret the data included in its header. in this project, you use wireshark to capture your own http messafes, examine the tcp headers, and practice interpreting the data you'll find there. 1. open wireshark and snap the window to one side of your screen. open a browser and snap that window to the other side of your screen so you can see both windows.
