On a roulette wheel, the pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Write a program that asks the user to enter a pocket number and displays whether the pocket is green, red, or black. The program should display an error message if the user enters a number that is outside the range of 0 through 36.
Answer:
pkt = int(input("Pocket Number: "))
if pkt == 0:
print("Green")
elif pkt >= 1 and pkt <=10:
if pkt%2 == 0:
print("Black")
else:
print("Red")
elif pkt >= 11 and pkt <=18:
if pkt%2 == 0:
print("Red")
else:
print("Black")
elif pkt >= 19 and pkt <=28:
if pkt%2 == 0:
print("Black")
else:
print("Red")
elif pkt >= 29 and pkt <=36:
if pkt%2 == 0:
print("Red")
else:
print("Black")
else:
print("Error")
Explanation:
The program was written in Python and the line by line explanation is as follows;
This prompts user for pocket number
pkt = int(input("Pocket Number: "))
This prints green if the pocket number is 0
if pkt == 0:
print("Green")
If pocket number is between 1 and 10 (inclusive)
elif pkt >= 1 and pkt <=10:
This prints black if packet number is even
if pkt%2 == 0:
print("Black")
Prints red, if otherwise
else:
print("Red")
If pocket number is between 11 and 18 (inclusive)
elif pkt >= 11 and pkt <=18:
This prints red if packet number is even
if pkt%2 == 0:
print("Red")
Prints black, if otherwise
else:
print("Black")
If pocket number is between 19 and 28 (inclusive)
elif pkt >= 19 and pkt <=28:
This prints black if packet number is even
if pkt%2 == 0:
print("Black")
Prints red, if otherwise
else:
print("Red")
If pocket number is between 29 and 36 (inclusive)
elif pkt >= 29 and pkt <=36:
This prints red if packet number is even
if pkt%2 == 0:
print("Red")
Prints black, if otherwise
else:
print("Black")
Prints error if input is out of range
else:
print("Error")
A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode, in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main:
List: [3, 1, 7, 1, 4, 10]
Mode: 1
Median: 3.5
Mean: 4.33333333333
#Here is the code I am using:
def median(list):
if len(list) == 0:
return 0
list.sort()
midIndex = len(list) / 2
if len(list) % 2 == 1:
return list[midIndex]
else:
return (list[midIndex] + list[midIndex - 1]) / 2
def mean(list):
if len(list) == 0:
return 0
list.sort()
total = 0
for number in list:
total += number
return total / len(list)
def mode(list):
numberDictionary = {}
for digit in list:
number = numberDictionary.get(digit, None)
if number == None:
numberDictionary[digit] = 1
else:
numberDictionary[digit] = number + 1
maxValue = max(numberDictionary.values())
modeList = []
for key in numberDictionary:
if numberDictionary[key] == maxValue:
modeList.append(key)
return modeList
def main():
print ("Mean of [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]: "), mean(range(1, 11))
print ("Mode of [1, 1, 1, 1, 4, 4]:"), mode([1, 1, 1, 1, 4, 4])
print ("Median of [1, 2, 3, 4]:"), median([1, 2, 3, 4])
main()
The Error that I am getting is on Line 14: AttributeError: 'range'object has no attribute 'sort'.
Also on Line 36:
Line36: 10]: "), mean(range1, 11)).
Answer:
In Python:
def median(mylist):
mylist.sort()
if len(mylist) % 2 == 1:
midIndex = int((len(mylist) +1)/ 2)
print("Median: "+str(mylist[midIndex-1]))
else:
midIndex = int((len(mylist))/ 2)
Mid = (mylist[midIndex] + mylist[midIndex-1] )/2
print("Median: "+str(Mid))
def mean(mylist):
isum = 0
for i in range(len(mylist)):
isum += mylist[i]
ave = isum/len(mylist)
print("Mean: "+str(ave))
def mode(mylist):
print("Mode: "+str(max(set(mylist), key=mylist.count)))
Explanation:
Your program is a bit difficult to read and trace. So, I rewrite the program.
This defines the median function
def median(mylist):
This sorts the list
mylist.sort()
This checks if the list count is odd
if len(mylist) % 2 == 1:
If yes, it calculates the mid index
midIndex = int((len(mylist) +1)/ 2)
And prints the median
print("Median: "+str(mylist[midIndex-1]))
else:
If otherwise, it calculates the mid indices
midIndex = int((len(mylist))/ 2)
Mid = (mylist[midIndex] + mylist[midIndex-1] )/2
And prints the median
print("Median: "+str(Mid))
This defines the mean function
def mean(mylist):
This initializes sum to 0
isum = 0
This iterates through the list
for i in range(len(mylist)):
This calculates the sum of items in the list
isum += mylist[i]
This calculates the mean
ave = isum/len(mylist)
This prints the mean
print("Mean: "+str(ave))
This defines the mode
def mode(mylist):
This calculates and prints the mode using the max function
print("Mode: "+str(max(set(mylist), key=mylist.count)))

Sentence Deobfuscate Name this file deobfuscate.cpp Hints: Don’t overthink this problem. Prompt the user to enter a collection of sentence words (i.e., words in the sentence), with the spaces removed (i.e., the obfuscated sentence) and with words that are less than ten (10) letters each. Then prompt the user to enter a sequence of numbers that represent the length of each corresponding sentence word (i.e. the deobfuscated details). Output the deobfuscated sentence. Convert char c to int by subtracting 48 (‘0’) from c.
Sample Execution:
Please enter obfuscated sentence: Thisisasentence
Please enter deobfuscation details: 4218
Deobfuscated sentence: This is a sentence
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
string text,lengt;
cout<<"Please enter obfuscated sentence: "; cin>>text;
cout<<"Please enter deobfuscation details: "; cin>>lengt;
string t1, t2;
int kount = 0;
for(int i = 0;i<lengt.length();i++){
kount+=(int)(lengt[i]-'0');
t1 = text.substr(0, kount);
t2 = text.substr(kount, text.length()-1);
text = t1 +" "+ t2;
kount++; }
cout<<"Deobfuscated sentence: "<<text;
return 0; }
Explanation:
This declares the text and the deobfuscation details as string
string text,lengt;
This prompts for the sentence
cout<<"Please enter obfuscated sentence: "; cin>>text;
This prompts for the details
cout<<"Please enter deobfuscation details: "; cin>>lengt;
t1 and t2 are declared as string. They are used to split the texts into 2 parts
string t1, t2;
This declares and initializes a count variable to 0
int kount = 0;
This iterates through the deobfuscation details
for(int i = 0;i<lengt.length();i++){
This gets each deobfuscation character
kount+=(int)(lengt[i]-'0');
The next two instructions splits the text into 2
This gets from 0 to kount.
t1 = text.substr(0, kount);
This gets from kount to the last index
t2 = text.substr(kount, text.length()-1);
The new string or sentence is calculated here
text = t1 +" "+ t2;
The kount variable is incremented by 1
kount++; } The loop ends here
This prints the new sentence
cout<<"Deobfuscated sentence: "<<text;

Which of the statements below describe how to print a document?
Write a C program that gets 4 integer values from the user, namely, x1, x2, y1, and y2, and then calculates and returns the distance according to the above formula. Use whatever format for entering your data you like. Your program should prompt the user for these values, accept input from the keyboard, and then print out the result. You will have to execute the program four times to cover the test cases below (feel free to use a loop if you want to work ahead). Include a screenshot (or four) that shows the results for the following values: 1) (2,3), (4,5) 2) (4,3), (-6,-5) 3) (-1,3), (4,-2) 4) (-9,-12), (-7, -8)
Answer:
#include <stdio.h>
#include <math.h>
int main(){
float x1,x2,y1,y2,distance;
printf("x1: "); scanf("%f", &x1);
printf("y1: "); scanf("%f", &y1);
printf("x2: "); scanf("%f", &x2);
printf("y2: "); scanf("%f", &y2);
distance = sqrt((x1 - x2)*(x1 - x2) + (y1 - y2)*(y1 - y2));
printf("Distance: %f", distance);
return 0;
}
Explanation:
This line declares all required variable (i.e. the coordinates and the distance)
float x1,x2,y1,y2,distance;
The next four line prompt and get input for the coordinates
printf("x1: "); scanf("%f", &x1);
printf("y1: "); scanf("%f", &y1);
printf("x2: "); scanf("%f", &x2);
printf("y2: "); scanf("%f", &y2);
This calculates the distance
distance = sqrt((x1 - x2)*(x1 - x2) + (y1 - y2)*(y1 - y2));
This prints the calculated distance
printf("Distance: %f", distance);

differentiate between system software and application software
Answer:
system software is the software which control overall operation of the computer . For eg. Ms.dos ,window 2003 ,etc whereas application software is a software which work on the top of operating system to solve number of problems .For eg. Ms.word,Ms.excel,etc
1.) System software is used for operating computer hardware. On other hand Application software is used by user to perform specific task.
2.) Low level languages are used to write the system software. While high level languages are used to write the application software.
3.) System Software a general purpose software. While application software a specific purpose software.
4.) Without system software, system can’t run. While without application software system always runs.
5.) System software runs when system is turned on and stop when system is turned off. While application software runs as per the user’s request.
6.) System Software programming is complex than application software. Application software programming is simpler as comparison to system software.
