Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending whe

dalvyx [7]

Answer:

string=""

while string not in {"Quit","quit","q"}:

string=input("Enter line to be reversed") #line of text will be entered

if string!="Quit" and string!="quit" and string!="q": #If quit is not entered

print("Reverse of line is : ")

print(string[::-1])

OUTPUT :

Enter line to be reversedThis code is in python language

Reverse of line is :

egaugnal nohtyp ni si edoc sihT

Enter line to be reversedHello world

Reverse of line is :

dlrow olleH

Enter line to be reversedquit

Explanation:In the above program, First a while loop is executed and checked if line of text is not 'quit', 'Quit' or 'q'. If condition is true, then loop is executed and in python any string or list can be traversed from end if step is given -1. Similarly line of text is accessed from the last element. If quit is entered, then the program will be broken out of the loop.

Write a program that uses the Purchase class in 5.13. Set the prices to the following: Oranges: 10 for $2.99 Eggs: 12 for $1.69

Xelga [282]

Answer:

Explanation:

The following program is written in Java. Using the program code from Purchase class in 5.13 I created each one of the fruit objects. Then I set the price for each object using the setPrice method. Then I set the number of each fruit that I intended on buying with the setNumberBought method. Finally, I called each objects getTotalCost method to get the final price of each object which was all added to the totalCost instance variable. This instance variable was printed as the total cost of the bill at the end of the program. My code HIGHLIGHTED BELOW

//Entire code is in text file attached below.

//MY CODE HERE

DecimalFormat df = new DecimalFormat("0.00");

oranges.setPrice(10, 2.99);

oranges.setNumberBought(2*12);

eggs.setPrice(12, 1.69);

eggs.setNumberBought(2*12);

apples.setPrice(3, 1);

apples.setNumberBought(20);

watermelons.setPrice(1, 4.39);

watermelons.setNumberBought(2);

bagels.setPrice(6, 3.50);

bagels.setNumberBought(12);

totalCost = oranges.getTotalCost() + eggs.getTotalCost() + apples.getTotalCost() + watermelons.getTotalCost() + bagels.getTotalCost();

System.out.println("Total Cost: $" + df.format(totalCost));

}

A direct-mapped cache holds 64KB of useful data (not including tag or control bits). Assuming that the block size is 32-byte and

Cerrena [4.2K]

Answer:

A) Number of bits for byte = 6 bits

B) number of bits for index = 17 bits

C) number of bits for tag = 15 bits

Explanation:

Given data :

cache size = 64 kB

block size = 32 -byte

block address = 32 -bit

number of blocks in cache memory

cache size / block size = 64 kb / 32 b = 2^11 hence the number of blocks in cache memory = 11 bits = block offset

A) Number of bits for byte

$log _{2} (6)^2$ = 6 bits

B) number of bits for index

block offset + byte number

= 11 + 6 = 17 bits

c ) number of bits for tag

= 32 - number of bits for index

= 32 - 17 = 15 bits
