Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase.
Answer:
The program in Python is as follows:
print("Enter a character followed by a phrase",end='')
word = input(": ")
char = word[0]
print("Occurrence: "+str((word.count(char))-1))
Explanation:
The prints an instruction to the user on how to input to the system
print("Enter a character followed by a phrase",end='')
This prompts and gets the user for input
word = input(": ")
This extracts the character from the input string
char = word[0]
This counts and prints the number of occurrence of the extracted character
print("Occurrence: "+str((word.count(char))-1))

Write a loop to populate the list user_guesses with a number of guesses. Each guess is an integer. Read integers using int(input()).
Answer:
num_of_guesses = int(input())
user_guesses = []
for n in range(num_of_guesses) :
guess_value = int(input())
user_guesses.append(guess_value)
print("User guesses :", user_guesses)
Explanation:
Using python
Line 1 prompts the user to input the number of guesses he / she will like to make.
Line 2, initiates an empty list which will be used to store the numbers which will be guessed.
The for loop which uses the condition stated in line 1, that is, the user will only be able to make guesses based on the value enters into num_of_guesses
guess_value prompts user to enter a value which is added to the user_guesses list
The print statement, lists the numbers guessed by the user.

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of integers as input, and outputs the average and max.
Answer:
Explanation:
The following code is written in Python. It is a function that takes in a list of ints as a parameter. It then creates two variables one for sum and for max. It then loops through the list adding all the values to sum and adding only the largest value to max. Then it creates a variable called avg which calculates the average by dividing the variable sum by the number of elements in the list. Finally, it returns both avg and max to the user.
def avg_and_max(my_list):
sum = 0
max = 0
for x in my_list:
sum += x
if x > max:
max = x
avg = sum / len(my_list)
return avg, max
Design and implement an application that reads a set of values in the range 1 to 100 from the user and then creates a chart showing how often the values appeared
Answer:
import random
import matplotlib.pyplot as plt
n = int(input("Enter the number of values: "))
mylist = random.choices(range(1,100), k= n)
plt.hist(mylist, bins=[1,10,20,30,40,50,60,70,80,90,100])
plt.xlabel(" Numbers")
plt.ylabel(" Frequency")
plt.show()
Explanation:
The python progam creates an histogram where the x axis is a list of random numbers in the range of 1 to 100. The program uses the random and matplotlib packages. The random module is used to get the a list of randomly selected values from a range of 1 to 100 and the matplotlib denoted as plt is use to plot a chart of the list as the x-axis and the frequency of the number values in the list.
Which threat hunting technique is best suitable when handling datasets that creates limited number of results
Answer:
Stacking
Explanation:
Threat hunting is searching through networks and datasets to see if their are suspicious or activities that are risky.
Stacking has to do with counting the frequency the frequency of occurrences for those values that are of o particular type. And then making an analysis) examination of the outliers of these results.
When the dataset is large or diverse, the effectiveness of the stacking technique reduces. It is best used with datasets that would give a finite number of results.

7. Which cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem
Answer:
The concealment cipher.
Explanation:
A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.
The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.
Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.

Full virtualization is ideal for ___________. Migration capacity Computer system sharing,isolate users Disaster recovery Data replication
Answer:
Computer system sharing, isolate users
Explanation:
Full virtualization is ideal for "Computer system sharing, isolate users." This is evident in the fact that Full virtualization is a technique in which data are shared between operating systems and their hosted software. This strategy is then carried out from the top of the virtual hardware.
Also, the full virtualization strategy in computer service requests is distinguished from the physical hardware that enables them.
Hence, in this case, the correct answer is "Computer system sharing, isolate users."

process?
A chlorobromide
B. bromide
C. chloride
D platinum
Answer:
A. Chlorobromide
Explanation:
I took the test and got it right. (Plato)
The type of black-and-white paper emulsion should be used by Jim is chlorobromide. Thus, option (A) is correct.
What is emulsion?A sort of colloid called an emulsion is created by mixing two liquids that wouldn't typically mix. A dispersion of the other liquid is present in one liquid in an emulsion.
Emulsions frequently occur in foods like egg yolk, butter, and mayonnaise. Emulsification is the process of combining liquids to create an emulsion.
According to the above scenario, Jim wishes to expand a warm-toned black-and-white photograph. For this purpose, he should use chlorobromide for black-and-white paper emulsion.
Paper covered with a chemical compound that is light-sensitive, which is inferred as photographic paper. When exposed to light, it captures the latent image.

Define the summary function, which takes as arguments a database (dict) and a dict of current stock prices. It returns a dictionary (dict or defaultdict) whose keys are client names (str) whose associated values are 2-tuples: the first index is a dictionary (dict or defaultdict) whose keys are stock names (str) and values are the number of shares (int) the client owns. The second index is the amount of money (int) the portfolio is worth (the sum of the number of shares of each stock multiplied by its current price). Assume each client starts with no shares of any stocks, and if a client owns 0 shares of a stock, the stock should not appear in the client’s dictionary. Recall positive numbers are a purchase of the stock and negative numbers a sale of the stock. E.g., if db is the database above, calling summary(db, {'IBM':65, 'Intel':60, 'Dell':55, 'Apple':70}) would return
Write a procedure that takes a positive integer as a parameter. If the number given to the procedure is no more than 30, the procedure should return the absolute difference between that number and 30
Question (continuation):
If the number is greater than 30, the procedure should return the number doubled.
Answer:
The procedure written in C++ is as follows:
void absdiff(int num){
if(num<=30){
num = abs(num - 30);
}
else{
num*=2;
}
cout<<num;
}
Explanation:
This defines the procedure
void absdiff(int num){
This checks if the integer parameter is not more than 30.
if(num<=30){
If yes, the absolute difference between 30 and the number is calculated
num = abs(num - 30);
}
If otherwise
else{
The number is doubled
num*=2;
}
This prints the processed result
cout<<num;
