Answer:
The program in Python is as follows:
string = input("String: ")
chr = input("Character: ")[0]
total_count = string.count(chr)
print(total_count,end=" ")
if total_count > 1:
print(chr+"'s")
else:
print(chr)
Explanation:
This gets the string from the user
string = input("String: ")
This gets the character from the user
chr = input("Character: ")[0]
This counts the occurrence of the character in the string
total_count = string.count(chr)
This prints the total count of characters
print(total_count,end=" ")
If the count is greater than 1
if total_count > 1:
Then it prints a plural form
print(chr+"'s")
If otherwise
else:
Then it prints a singular form
print(chr)
A security team has downloaded a public database of the largest collection of password dumps on the Internet. This collection contains the cleartext credentials of every major breach for the last four years. The security team pulls and compares users' credentials to the database and discovers that more than 30% of the users were still using passwords discovered in this list. Which of the following would be the BEST combination to reduce the risks discovered?
a. Password length, password encryption, password complexity
b. Password complexity least privilege, password reuse
c. Password reuse, password complexity, password expiration
d. Group policy, password history, password encryption
Answer:
a. Password length, password encryption, password complexity
Explanation:
Under this scenario, the best combination would be Password length, password encryption, password complexity. This is because the main security problem is with the user's passwords. Increasing the password length and password complexity makes it nearly impossible for individuals to simply guess the password and gain access, while also making it extremely difficult and time consuming for hackers to use software to discover the password as well. Password excryption would be an extra layer of security as it encrypts the password before storing it into the database, therefore preventing eavesdroppers from seeing the password and leaked info from being used without decryption.
A train protection system automatically applies the brakes of a train if the speed limit for a segment of track is exceeded, or if the train enters a track segment that is currently signaled with a red light (i.e., the segment should not be entered). There are two critical-safety requirements for this train protection system:
The train shall not enter a segment of track that is signaled with a red light.
The train shall not exceed the specified speed limit for a section of track.
Assuming that the signal status and the speed limit for the track segment are transmitted to on-board software on the train before it enters the track segment, propose five possible functional system requirements for the onboard software that may be generated from the system safety requirements.
Explanation:
Five possible functional system requirements for the onboard software that may be generated from the system safety requirements:
software should enable the brakes to be applied instantly when the red light is signaled.speed of the train should be monitored when it's running on a segment so that it does not exceed the maximum speed limit.important for the system to examine the color displayed before a train enters a segment of the track.constant checking of the speed limit and color of the light so as to determine when the brakes should be applied. when there is a red light the system should notify/prevent the train from entering the segment.Crop-Harvesting robots manage harvest automation, seeding, and weeding.

def shared_motif(dna_list):
This function takes in a list of DNA strings and returns the longest common substring. A substring is a contiguous sequence of characters within a string. A common substring is a substring of every element in the given list of DNA strings. Note that the number of DNA strings in the input list is not always the same! There may be multiple solutions, but you only need to return the first one.
Example:
Sample input DNA list:
("GATTACA", "TAGACCA", "ATACA"]
The returned longest common substring:
"TA"
Answer:
Explanation:
The following code is written in Python, the function creates various nested loops to loop through each individual string comparing letter by letter in order to find the longest common substring. Finally, returning the substring itself.
def shared_motif(dna_list):
substr = ''
if len(dna_list) > 1 and len(dna_list[0]) > 0:
for x in range(len(dna_list[0])):
for i in range(len(dna_list[0]) - x + 1):
if i > len(substr) and all(dna_list[0][x:x + i] in y for y in dna_list):
substr = dna_list[0][x:x + i]
return substr
arr = ["GATTACA", "TAGACCA", "ATACA"]
stems = shared_motif(arr)
print(stems)

Apart from the OOPs concepts learned in this lesson, identify additional concepts and write an essay on their functions. Explain how they are used in a program.
PLSSSS HELLP MEEE ASAP!!!!
Explanation:
Object Oriented Programming (OOPS or OOPS for Object Oriented Programming System) is the most widely used programming paradigm today. While most of the popular programming languages are multi-paradigm, the support to object-oriented programming is fundamental for large projects. Of course OOP has its share of critics. Nowadays functional programming seems the new trendy approach. Still, criticism is due mostly to misuse of OOP.

Write a C program that right shifts an integer variable 4 bits. The program should print the integer in bits before and after the shift operation. Does your system place 0s or 1s in the vacated bits?
Solution :
#include<[tex]$\text{stdio.h}$[/tex]>
#include<conio.h>
void dec_bin(int number) {
[tex]$\text{int x, y}$[/tex];
x = y = 0;
for(y = 15; y >= 0; y--) {
x = number / (1 << y);
number = number - x * (1 << y);
printf("%d", x);
}
printf("\n");
}
int main()
{
int k;
printf("Enter No u wanted to right shift by 4 : ");
scanf("%d",&k);
dec_bin(k);
k = k>>4; // right shift here.
dec_bin(k);

Implement the function _isPalindrome() in palindrome.py, using recursion, such that it returns True if the argument s is a palindrome (ie, reads the same forwards and backwards), and False otherwise. You may assume that s is all lower case and doesn’t include any whitespace characters.
Answer:
The function is as follows:
def _isPalindrome(stri) :
if len(stri) == 0:
return True
if stri[0] == stri[len(stri) - 1]:
return _isPalindrome(stri[1:len(stri) - 1])
else:
return False
Explanation:
This defines the function
def _isPalindrome(stri) :
If the string is empty, then it is palindrome
if len(stri) == 0:
return True
This checks if the characters at alternate positions are the same.
If yes, it calls the function to check for other characters
if stri[0] == stri[len(stri) - 1]:
return _isPalindrome(stri[1:len(stri) - 1])
If otherwise, the string is not palindrome
else:
return False
To reduce the number of used digital outputs of the microcontroller, the display board is connected to the main board through the integrated circuit of the decoder, which converts binary coded decimal (BCD) values to signals for the seven-segment display. So, to show any number on the display you need to set the required BCD code on the microcontroller's outputs. Write a program to convert an integer number represented as a string to a BCD code required for the display. In the BCD code, every decimal digit is encoded with its four-bit binary value. Encoding all digits of the decimal number and concatenating the resulting codes into one string you will get a resulting BCD code. A space is used to separate digits in the BCD code and make it more readable. For example, a number 173 will be encoded to BCD as 0001 0111 0011.
Answer:
The program in Python is as follows:
BCD = ["0001","0010","0011","0100","0101","0110","0111"]
num = input("Decimal: ")
BCDValue = ""
valid = True
for i in range(len(num)):
if num[i].isdigit():
if(int(num[i])>= 0 and int(num[i])<8):
BCDValue += BCD[i]+" "
else:
valid = False
break;
else:
valid = False
break;
if(valid):
print(BCDValue)
else:
print("Invalid")
Explanation:
This initializes the BCD corresponding value of the decimal number to a list
BCD = ["0001","0010","0011","0100","0101","0110","0111"]
This gets input for a decimal number
num = input("Decimal: ")
This initializes the required output (i.e. BCD value) to an empty string
BCDValue = ""
This initializes valid input to True (Boolean)
valid = True
This iterates through the input string
for i in range(len(num)):
This checks if each character of the string is a number
if num[i].isdigit():
If yes, it checks if the number ranges from 0 to 7 (inclusive)
if(int(num[i])>= 0 and int(num[i])<8):
If yes, the corresponding BCD value is calculated
BCDValue += BCD[i]+" "
else:
If otherwise, then the input string is invalid and the loop is exited
valid = False
break;
If otherwise, then the input string is invalid and the loop is exited
else:
valid = False
break;
If valid is True, then the BCD value is printed
if(valid):
print(BCDValue)
If otherwise, it prints Invalid
else:
print("Invalid")

The L-exclusion problem is a variant of the starvation-free mutual exclusion problem. We make two changes: as many as L threads may be in the critical section at the same time, and fewer than L threads might fail (by halting) in the critical section. An implementation must satisfy the following conditions:_____.
L-Exclusion: At any time, at most L threads are in the critical section.
L-Starvation-Freedom: As long as fewer than L threads are in the critical section, then some thread that wants to enter the critical section will eventually succeed (even if some threads in the critical section have halted).
Modify the n-process Bakery mutual exclusion algorithm to turn it into an L-exclusion algorithm. Do not consider atomic operations in your answer. You can provide a pseudo-code solution or written solution.
Answer:
The solution is as follows.
class LFilters implements Lock {
int[] lvl;
int[] vic;
public LFilters(int n, int l) {
lvl = new int[max(n-l+1,0)];
vic = new int[max(n-l+1,0)];
for (int i = 0; i < n-l+1; i++) {
lvl[i] = 0;
}
}
public void lock() {
int me = ThreadID.get();
for (int i = 1; i < n-l+1; i++) { // attempt level i
lvl[me] = i;
vic[i] = me;
// rotate while conflicts exist
int above = l+1;
while (above > l && vic[i] == me) {
above = 0;
for (int k = 0; k < n; k++) {
if (lvl[k] >= i) above++;
}
}
}
}
public void unlock() {
int me = ThreadID.get();
lvl[me] = 0;
}
}
Explanation:
The code is presented above in which the a class is formed which has two variables, lvl and vic. It performs the operation of lock as indicated above.
Create a PetStore class, a Dog class, and Cat class. Once instantiated, a PetStore should be able to take in and give out pets. The store's method for receiving pets should be called receive. This method should take a single pet object (either a Dog or Cat instance) and should add it to the store's inventory of pets. The store's method for giving out a pet should be called sell and can take no arguments. The method returns a pet when called.
