Procedure TreeSearch (x, K) i if (x = NIL) or (K = x. key) then 2 return (x); 3 else if (K < x. key) then 4 | TreeSearch (x. left, K); 5 else 6 TreeSearch (x. right, K); 7 endConsider a binary search tree where each tree node v has a field v. sum which stores the sum of all the keys in the subtree rooted at v.
We wish to add an operation SumLE(K) to this binary search tree which returns the sum of all the keys in the tree whose values are less than or equal to K.
(a) Describe an algorithm, SumLE(K), which returns the sum of all the keys in the tree whose values are less than or equal to K. Give pseudo-code for your algorithm. Your algorithm should take the same time as operation TreeSearch from slide 7.12.
(b) Explain why your algorithm is correct, i. e., why it returns the sum of all the keys whose values are less than or equal to K.
(c) Analyze the running time of your algorithm in terms of the size n and height h of the binary search tree.

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e. g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).
