Determine for the following code how many pages are transferred between disk and main memory (you must count reads and writes separately!), assuming each page has 1000 words, the active memory set size is 1000 (i. e., at any time no more than 1000 pages may be in main memory), and the replacement strategy is LRU (the Least Recently Used page is always replaced); also assume that all two-dimensional arrays are of size (1:2000, 1:2000), with each array element occupying one word, for i := 1 to 4000 do
for J :=1 to 4000 do

{ A[I, J]:=A[I, J]*B[I, J]; }

provided the arrays are mapped into the main memory space (a) in row-major order, (b) in column-major order.

In excel - calculate the actual increase/decrease from first quarter to the second quarter then subtract subtract first quarter value from second quarter total then divide result by first quarter value

File account. java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
