A palindrome is a string that reads the same forward and backward. a substring is a contiguous subset of characters in a string. Given a string s how many distinct substrings of s are palindromes
Answers
Answer:
Here is the Python program to compute how many distinct substrings of a string s are palindromes:
def AllPalindromes(s, l, h, sub): #function that finds all the palindromes
while l >= 0 and h < len(s) and s[l] == s[h]: #the loop iterates and reads the s until s[l.h] is a palindrome
sub.add(s[l: h + 1]) #adds the palindromes to sub
l = l - 1 #decrements the count of l by 1
h = h + 1 #increments the count of h by 1
def DistinctPalindromes(s): #function to find all distinct palindromic substrings of s and also their number
substr = set() #stores all distinct substrings of s which are palindromes
for i in range(len(s)): #iterates through s
AllPalindromes(s, i, i,substr) # find all palindromes with odd length and with s[i] as mid point
AllPalindromes(s, i, i + 1, substr) # find all palindromes with even length and with s[i] as mid point
print("palindromic substrings are",substr, '\n',end='') # display all distinct palindromic substrings
print(len(substr),"distinct substrings of",s,"are palindromes") # display the number of distinct palindromic substrings
print("Enter a string:") #prompts user to enter a string
s = input() #accepts input from user
DistinctPalindromes(s) #calls DistinctPalindromes method by passing input string to it in order to compute the
Explanation:
The program is well explained in the comments attached with each statement of the code. The function AllPalindromes finds all the palindromes of string s. while loop iterates and reads the string forward and backward to find same i.e. palindrome. Here h and l represents high and low part of the string s. They can also be called as forward and backward pointers to the s characters. The while condition also checks the characters at s[l] position in the string s is equal to the character at s[h]. add() method is used to push all palindromes into the set sub. The function DistinctPalindromes is used to find all the distinct substrings of s that are palindromes. The loop iterates through characters of string s and calls AllPalindromes method to find all palindromes with odd and even length. It then prints the distinct palindromic substrings . For examples s = "aabaa" then the palindromic substrings are {'aabaa', 'b', 'aba', 'a', 'aa'} and the number of distinct substrings of aabaa that are palindromes is 5. The program along with its output is attached in a screenshot.

Describe and define each of the following tkinter widgets:
a) Label
b) Entry
c) Button
d) Frame
Answers
Answer:
Tkinter in Python comes with a lot of good widgets. Widgets are standard graphical user interface (GUI) elements, like different kinds of buttons and menus. Ttk comes with 17 widgets, eleven of which already existed in tkinter:
Button Checkbutton Entry Frame Label LabelFrame Menubutton PanedWindow Radiobutton Scale and ScrollbarThe other six are new: Combobox, Notebook, Progressbar, Separator, Sizegrip and Treeview. And all them are subclasses of Widget.
Explanation:
The Label widget is a standard Tkinter widget used to display a text or image on the screen. The label can only display text in a single font, but the text may span more than one line. In addition, one of the characters can be underlined, for example to mark a keyboard shortcut.Entry widgets are the basic widgets of Tkinter used to get input, i.e. text strings, from the user of an application. This widget allows the user to enter a single line of text. If the user enters a string, which is longer than the available display space of the widget, the content will be scrolled.The Button widget is a standard Tkinter widget used to implement various kinds of buttons. Buttons can contain text or images, and you can associate a Python function or method with each button. When the button is pressed, Tkinter automatically calls that function or method.A frame is rectangular region on the screen. The frame widget is mainly used as a geometry master for other widgets, or to provide padding between other widgets.The definition of widgets is given:
a) Label - It is a common Tkinter widget that displays text or an image on the screen.
b) Entry - They are the fundamental Tkinter widgets used to collect input, i.e. text strings, from an application's user.
c) Button - it is a Tkinter standard that is used to implement various types of buttons.
d) Frame - it is a rectangle on the screen. The frame widget is primarily used as a geometry master for other widgets or as padding between other widgets.
What are Tkinter widgets?Tkinter in Python includes a plethora of useful widgets. Widgets are graphical user interface (GUI) elements that include various types of buttons and menus.
The label can only display text in one font, but the text can span multiple lines. Furthermore, one of the characters can be highlighted, for example, to indicate a keyboard shortcut.
Therefore, the definitions of the widgets are given above.

If two classes combine some private data members and provides public member functions to access and manipulate those data members. Where is abstraction used?a. Using private access specifier for data membersb. Using class concept with both data members and member functionsc. Using public member functions to access and manipulate the data membersd. Data is not sufficient to decide what is being used
Answers
Answer:
c. Using public member functions to access and manipulate the data members
Explanation:
In object oriented programming, abstraction is used in order to lessen the complexity and hiding non essential details about how a program is actually working in the background. In order to achieve abstraction, classes are defined in such a way that the data members are hidden and the member functions form public interface. The public member functions here are used to access and manipulate these hidden or private data members. So the use of public member functions shows the abstraction here. These members functions are public so they can be directly accessed and the hidden or private data members can be accessed indirectly with the help of these member functions. So internal details of the classes and its data members are hidden from the outside world. Thus abstraction used here ensures security of data members of two classes and protects them from any accidental alterations by other parts of program.

In no less than two paragraphs, explain the risks and compliance requirements of moving data and services into the cloud.
Answers
Answer:
Compliance requirements of moving data and services into the cloud:
In other to use cloud services, one has to comply or follow the rules of the service providers, the country of the location where these services are provided. All these are necessary for the safety of the data stored in the cloud.
Some countries, regions, often set up rules guarding usage and storing data in the cloud. So it is very important to be aware of this. For instance, some countries enforce data localization laws which make data of its citizen stored in the servers of the country. Here, the country has full protection over the data hosted.
There are also data sovereignty laws that give the country hosting the data a sort of authority to exercise in accordance with the law binding cloud data hosting in their region. This gives the country easy access to information in case of any legal means.
So, when choosing a cloud application, it’s important for an organization to select an application that will aid in cloud compliance and improve your security posture, not create more risk.
It is very important to first know which law is applicable to the country one is residing so as to comply with cloud usage to avoid fines and legal cases.
Risks of moving data and services into the cloud
It is good before using cloud services to know who could possibly have access to the data, if it is safe, how long could data be stored.
If there are unauthorized use of cloud services, the organization providing the service might not be aware of the safety of the hosted data which eventually decreases an organization's visibility and control of its network and data.
Data stored in the cloud could become incomplete, stolen, lost.
The client might not be able to control who else has access to the stored data.
Moving data and services into the cloud could become unattractive again as organizations could lose clients and revenue if clients' trust no longer exists.
