A company has written a large class BankingAccount with many methods including: Method/Constructor Description
public BankingAccount(Startup s) constructs a BankingAccount object using
information in the Startup object s
public void debit(Debit d) records the given debit
public void credit(Credit c) records the given credit
public int getBalance() returns current balance in pennies
Design a new class MinMaxAccount whose instances can be used in place of a BankingAccount object but include new behavior of remembering the minimum and maximum balances ever recorded for the account. You should provide the same methods as the superclass, as well as the following new behavior:
Method/Constructor Description
public MinMaxAccount (Startup s) constructs a MinMaxAccount object using
information in the Startup objects s
public int getMin() returns minimum balance in pennies
public int getMax() returns maximum balance in pennies
The account's constructor sets the initial balance based on the Startup information. Assume that only the debit and credit methods change an account's balance.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

Carlos, an algebra teacher, is creating a series of powerpoint presentations to use during class lectures. after writing, formatting, and stylizing the first presentation, he would like to begin writing the next presentation. he plans to insert all-new content, but he wants to have the same formatting and style as in the first one. what would be the most efficient way for carlos to begin creating the new presentation? going under the file tab and opening the first presentation, deleting all content from each page, and adding new content going under the file tab and clicking on new in the left pane, then choosing new from existing going under the design tab and clicking on themes, then selecting the theme that was used for the first template going under the design tab and opening the template that was created for the first presentation
