Swapping Order of Vowels Write a program to swap the order of the vowels in a given word. For example, if the word is programming, the output is prigrammong. Here, the initial order of vowels is o, a, i which changes to i, a, o. Assume that the letters of the words are in lowercase.
Answer:
Program is as follow:
Explanation:
#include<iostream.h>
#include < conio.h>
bool isVowel(char b)
{
return
( b=='a' || b=='A' || b=='e' || b=='E' || b=='i' || b=='I' || b=='o' || b=='O' || b== 'u' || b=='U');
For swaoing the vowels
string reverseVowel ( String str)
{
int j = 0;
string v ;
for ( int i= 0 ; str [i]]!='0'; i++)
if( isv(str[i]))
v[j++] = str[i[;
for ( int i = 0; str[i]! = '0' ; i++
if ( isv (str[i]))
str{i} = v [--j]
return str;
}
int main ()
{ string str = " Programming";
cout<<swapv(str);
return 0 ;
}
g Consider the turning point problem again, but this time you are given a sequence of at least three integers, which consists of a decreasing subsequence followed by an increasing subsequence. Using the divide and conquer technique, develop a recursive algorithm that finds the index of the turning point in the sequence (that is, the point where it transitions from a decreasing subsequence to an increasing subsequence). For example, in the sequence [43 30 16 10 7 8 13 22], the integer 7 is the turning point and its index is equal to 4 (assuming the starting index is 0). So, the algorithm should return 4
Answer:
Explanation:
The following code is written in Python, it creates a recursive function that takes in a list as a parameter, then compares the first two items in the list if the first is greater, it increases the index by one and calls the function again. This is done until the turning point is found, it then prints out the position of the turning point int the list.
def find_turning_point(list, x=0):
if list[x] > list[x + 1]:
x += 1
return find_turning_point(list, x)
else:
return "The turning point position is: " + str(x)

Design a software system for a bookstore that keeps an inventory of two types of books: Traditional books and books on CD. Books on CD may also contain music. The bookstore purchases books from publishers and sets a price for each book. Customers can purchase books from the bookstore, using either cash or a credit. The bookstore keeps track of which books it has in its inventory, and the books purchased by each customer
a. What are the objects in your object- oriented Solution?
b. What are the interactions between objects in your solution?
c. Which objects "have" other objects?
d. Which Objects "Use" other objects?
e. Which objects are other objects?
Answer:
Explanation:
a. In this scenario, the best solution would have an Object of Traditional Books, CD, Music, Bookstore and Customer.
b. All five objects would be able to be called by the main program loop and the Customer Object would call upon and use either the Books or CD object, While the Bookstore object would call upon all of the other objects.
c. Both the Bookstore object and Customer object will "have" other objects as the Bookstore needs to hold information on every Book or CD in the Inventory. While the Customer object would call upon the Book and CD object that they are purchasing.
d. The Music Object will extend the CD object and use information on the CD object as its parent class.
e. Since the Music Object extends the CD object it is also considered a CD since it is in CD format like the Books on CD and therefore is both objects.
Add the following method to the Point class: public double distance(Point other) Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
Answer:
public class Point
{
public int x;
public int y;
Point(int x,int y)
{
this.x=x;
this.y=y;
}
public static void main(String[] args)
{
Point p1=new Point(-2,3);
Point p2=new Point(3,-4);
System.out.println("distance:"+distance(p1,p2));
}
private static double distance(Point p1,Point p2)
{
return Math.sqrt(Math.pow(p2.x-p1.x, 2)+Math.pow(p2.y-p1.y, 2));
}
}
Explanation:
The java program defines the Point class and the public method 'distance' to return the total distance between the two quadrants passed to it as arguments (they are both instances of the Point class).

Lists are an example of a data abstraction.
A data abstraction can often contain different types of elements. It also provides a separation between the abstract properties of a data type (integer, boolean, string) and the concrete details of its representation. Basically, it doesn’t matter that the type are different!
Create an empty list. Append the integer 3, a string of "hello" and a boolean of False into the list. Print out each index individually. Now, remove the number 3 and False from the list.
Finally, print out the list again.
Answer:
Explanation:
The following Python code does exactly as requested. Once the list is created and the elements are added to it, it uses a for loop to print out each element individually. Then once the loop is over it removes the 3 and False elements from the list and creates another for loop to print the remaining element(s) individually again.
my_list = []
my_list.append(3)
my_list.append("hello")
my_list.append(False)
for x in my_list:
print(x)
my_list.remove(3)
my_list.remove(False)
for x in my_list:
print(x)

How does an online discussion group differ from one that is held face-to-face?
There is no need for group roles when holding online meetings.
Online discussion groups do not allow members to develop critical-thinking skills.
Group members are more likely to bond together as a group online than they would when meeting face-to-face.
Facilitating an online conversation may require even more work, so that participants continue engaging with one another online.
Answer: they always will have a different thinkage from others
Explanation:Some people need actual in person learning for better grades it also keeps them from getting distracted easily, they have different brains in everyone in the world everyone thinks, acts and talks in different ways some people dont need in person school because they would rather be online wich are both ok so yes they do bond together online but better in person.
Online discussion group differ from one that is held face-to-face as Group members are more likely to bond together as a group online than they would when meeting face-to-face. Thus, option C is correct.
What is software organization?A system that defines how specific activities, in this case, the software development process, are directed to achieve corporate goals is referred to as an organizational structure. These activities could include putting rules, roles, and responsibilities in place.
There are four basic modes of collaboration, as illustrated by the exhibit "The Four Ways to Collaborate": a closed and authoritarian network (an elite circle), an open and hierarchical connectivity (an innovation mall), an open and flat network (an innovation community), and a shuttered and flat network (a consortium).
Groupware is software that allows a group of people to work together on the same system or application, regardless of where they are. Email, newsgroups, and many more are examples of groupware applications.
Thus, option C is correct.

Greedy Algorithm Design
A couple wants to buy n major items. They will buy one item per month. They will buy all of their items at the CrazySuperStore. Due to the current economy, it is known that at some point in the future there will be a single price hike on all items at the same time, but due to the uncertainty of economic processes, it is not known when that price hike will occur. For each of the n items the couple wants to buy, both the current price, ai and the future price, bi (bi > ai), are known. (Note that the individual price hikes on items may vary. For example, one item may go from $100 to $105 while another might go from $300 to $400. They only assumption you may make about the prices is that the second price is strictly higher than the first and that you have access to all before/after prices.) Devise a greedy strategy so that the couple is guaranteed to minimize the amount of money they spend on the items. Assume that no matter what, the couple will buy all items. Clearly describe your strategy and intuitively (or formally) prove why it's optimal.
Answer:
The algorithm is as follows:
1. Start
2. Get the number of items (n)
3. Get the current price of the n items (a1, a2..... an)
4. Get the possible hiked price of the n items (b1, b2..... bn)
5. Calculate the difference between the current and hiked prices for each item i.e. [tex]d_i = b_i - a_i[/tex]
6. Sort the differences in descending order (i.e. from the greatest to the least)
7. Buy items in this order of difference
8. Stop
Explanation:
The algorithm is self-explanatory; however, what it does is that:
It takes a list of the current price of items (say list a)
E.g: [tex]a = [100, 150, 160][/tex]
Then take a list of the hiked price of the items (say list b)
E.g: [tex]b = [110, 180, 165][/tex]
Next, it calculates the difference (d) between corresponding prices [tex]d_i = b_i - a_i[/tex]
[tex]d = [(110 - 100),(180-150),(165-160)][/tex]
[tex]d = [10,30,5][/tex]
Sort the difference from greatest to lowest (as the difference is sorted, lists a and b are also sorted)
[tex]d = [30,10,5][/tex]
[tex]a = [150, 100, 160][/tex]
[tex]b = [180, 110, 165][/tex]
If there is no hike up to item k, the couple would have saved (i = 1 to d[k-1])
Assume k = 3
The couple would have saved for 2 item
[tex]Savings = d[1] + d[2][/tex]
[tex]Savings = 30 +10[/tex]
[tex]Savings = 40[/tex]
The saved amount will then be added to the kth item in list a i.e. a[k](in this case k = 3) in order to buy b[k]
Using the assumed value of k
[tex]a[k] = a[3][/tex]
[tex]a[3] = 160[/tex]
[tex]b[3] = 165[/tex]
Add the saved amount (40) to a[3]
[tex]New\ Amount = 40 + 160[/tex]
[tex]New\ Amount = 200[/tex]
This new amount can then be used to buy b[3] i.e. 165, then they save the change for subsequent items
In QBasic, create a number guessing challenge. Your program should generate a random number from 1-
100 (inclusive). Let the user guess a number. The program should let the user guess until they get the
correct number. After each input, the program should tell the user whether they guessed the correct
number, or if they guessed too high or too low. While the user is entering guesses, the program should
keep a count of the number of guesses that it takes to get the correct number. After the user guesses
the correct number, the program should congratulate the user and tell them how many guesses it took
them to get the correct number. By the way, if the user chooses carefully, they should be able to guess
the number within 7 tries. But, your program should still let the user keep guessing until they guess the
correct number

we are writing a program that takes a word and checks how many letters
Answer:
def word_count(word):
return len(word)
a = word_count('scream')
print(a
Explanation:
Using python3:
def word_count(word):
#defines a function named word_count which takes in a single argument which is the word to be counted
return len(word)
#The only thing the function does is to count the number letters in the word.
For instance :
return len(word)
Calling the function and attaching it to the variable named a
Counts the number of letters in scream and assigns the result to a
a = word_count('scream')
print(a)
a gives an output of 6 ; which is the number of letters in scream.
Assume that you have implemented a sequence class. Describe the mySequence object (i.e., items with the correct order and the position of the current index) after each line of the following code
sequence mySequence;
mySequence.insert(3)
mySequence.insert(2);
mySequence.attach(10);
mySequece.advance();
mySequence.attach(11);
mySequence.insert(4);
mySequence.insert(6);
mySequece.advance();
mySequence.remove_current();
mySequence.insert(9);
Answer:
The final sequence is: 2 10 3 6 9(c) 11
Explanation:
The first line of code creates the sequence object "mySequence". Every insert() method inserts the item before the current item to make a new current item. The attach() method adds a new current item after the previous current item. The advance() method makes the next item to the current item the new current item.
The remove_current method of the sequence object removes the current item of the sequence.

A palindrome is a string that is the same when read left to right as when read right to left. Write a program that determines if an arbitrary string is a palindrome. Assume that the string can have blanks, punctuation, capital letters and lower case.
Answer:
In Python:
strng = input("String: ")
revstrng = strng[::-1]
if strng == revstrng:
print("True")
else:
print("False")
Explanation:
This prompts user for string input
strng = input("String: ")
This reverses the string input by the user
revstrng = strng[::-1]
This checks if strings and the reverse string are equal
if strng == revstrng:
Prints True, if yes
print("True")
Prints False, if otherwise
else:
print("False")

You were just hired as an IT Specialist for Smalltown School District. Your first assignment is to review a problem area& in student records processing. It seems that the program currently used to compute student grade point averages and class rankings runs terribly slow and as a result end of year reports are habitually late. Your are asked to come up with a list of items that should be checked in order to determine if a modification to code is in order. The IT department head is asking you to do this without the opportunity to actually see the current application/programs in use. What questions would you ask about the current code? What areas of code would you look at? What would you need to know about the student data?
Answer:
Explanation:
There are various questions that you can ask in this scenario, such as
What grading policies are being implemented?
How many student grades are being calculated by the program?
What is the requirements for a student to pass?
All of these questions would allow you to get an idea of how extensive the code may be and its complexity. Once you know this you would look at the code revolving around actually looping through the data and doing the necessary calculations. You can then determine how to manipulate the code and make it much more efficient.
You would also need to know how the student data is being saved, which will help determine if it is the best data structure for saving this type of data or if it can be replaced in order to maintain the data secure while increasing the speed of the program. Mainly since this information needs to be continuously used from the data structure.
