Exercise 8-3 Encapsulate
fruit = "banana"
count = 0
for char in fruit:
if char == "a":
count += 1
print(count)
This code takes the word "banana" and counts the number of "a"s. Modify this code so that it will count any letter the user wants in a string that they input. For example, if the user entered "How now brown cow" as the string, and asked to count the w's, the program would say 4.
Put the code in a function that takes two parameters-- the text and the letter to be searched for. Your header will look like def count_letters(p, let) This function will return the number of occurrences of the letter.
Use a main() function to get the phrase and the letter from the user and pass them to the count_letters(p,let) function. Store the returned letter count in a variable. Print "there are x occurrences of y in thephrase" in this function.

In the question the information is missing the code is missing which we have to correct it following are the code that are mention below.
def factorial(n): # function
result=1 #variable
for x in range( ): #iterating the loop
result= #storing result

for n in range( ): #iterating loop
print(n,factorial(n)) #print factorial
Following are the description of code
We have create a function factorial in this we have pass the one parameter i.e "n".In the for loop we have pass 2,n+1 which has been used to iterating the loop calculating factorial and string the result in the result variable In the main function we have pass the range on which we have to calculated the factorialFinally the print function will print the factorial .Following are the attachment snip of code in the python language
By filling in the blanks to make the factorial function return the factorial of n, we have the following.
def factorial (n):
result = 1
for x in range(2, n+1):
result = result*x
return result
for n in range(10):
print(n,factorial(n))
The math module in Python includes a number series of mathematical operations that may be easily done using the module. The math . factorial() function computes the factorial of a given number.
To write the code perfectly and fill in the blanks:
We created a math factorial function with n parameterThis code is being passed through the iterating loop 2,n+1 for calculation. We string the result, perform the range, and print out the result using the print formula.CODE:
def factorial (n):

The percentage of the audience with TV sets turned on that is watching a particular program is known as the ____________________.
Answers
Answer:
Share.
Explanation:
Social media publishing also known as broadcasting, can be defined as a service that avails end users the ability to create or upload web contents in either textual, audio or video format in order to make them appealing to a target audience.
Thus, these multimedia contents are generally accessed by end users from time to time through the use of various network-based devices and television set. As users access these contents, they're presented with the option of sharing a particular content with several other people a number of times without any form of limitation.
Additionally, the demographic or amount of audience (viewers) that a television show or program is able to get to watch at a specific period of time is generally referred to as share.
Hence, the percentage of the audience with TV sets turned on that is watching a particular program is known as the share.
For example, the percentage of the audience tuned in to watch a champions league final on a Saturday night, 8:00pm via their television set.

Time complexity gives a rough idea of how long it will take for an algorithm to execute
based on two things: the size of the input it has and the amount of steps it takes to complete,
whereas space complexity is also the amount of memory required to execute an algorithm based
on the size of input it has or given.
Using mathematical notations or diagrams critically explain the time and space complexity of the
code below. 10 marks
int a = 0;
for (i = 0; i < N; i++) {
for (j = N; j > i; j--) {
a = a + i + j;
}
}
Answers
Answer:
Explanation:
O(N*N) or O(N2).
Explanation:
The time complexity can be measured by caculating the number of times the loop will execute.
The above code runs total no of times
= N + (N – 1) + (N – 2) + … 1 + 0
= N * (N + 1) / 2
= 1/2 * N^2 + 1/2 * N
O(N^2) times.
Thus Time complexity is O(N*N) or O(N2).
When i=0, it will run 0 times.
When i=1, it will run 1 times.
When i=2, it will run 2 times and so on.
So the time complexity will be O(N*N) or O(N2).
The function O(n2) has a complexity that is proportional to the square of the input size.
O(n2) with 2 total iterations.
O(N^2) is for → 2 nested “for loops”
We usually want to know how many steps an algorithm will take for an input of size ‘N' when calculating complexity.
This example contains two ‘for' loops, each of which will execute ‘N' times for each element ‘N'. As a result, it will run N2 times in total. In large O notation, we'd state the complexity of this algorithm is O(N2).
Time Complexity:
The amount of time it takes an algorithm to finish a computation.
What factors contribute to the complexity of time?
Looping (for, while)
Big O Notation:
The language and metric we use to describe how long an algorithm takes to run.
O(n²) Quadratic Time
Two nested loops are involved.
Each item from two different collections must be compared to one another.
Space Complexity:
Space complexity is the measurement of memory (space) that an algorithm requires, similar to time complexity.
What determines the complexity of space?
Variables
Allocations
Space Complexity: O(1) space
Because of the nested for loops The time complexity is going to be quadratic.
As a result, the Space Complexity will be O(1) space.
Worst case space complexity: O(1)
Hence,
Time Complexity: O(n²)
Space Complexity: O(1)

What is displayed in the alert dialog box after the following code is executed? var scores = [70, 20, 35, 15]; scores[scores.length] = 40; alert("The scores array: " + scores);
Answers
Answer:
The scores array: 70,20,35,15,40
Explanation:
I will explain the code line by line:
var scores = [70, 20, 35, 15];
The above statement declares and assigns values to an array named scores
scores[scores.length] = 40;
The above statement uses length to set the length of the scores array. It sets the last element of the scores array to 40. So this means 40 is set as the last element of scores.
scores.length returns the length of the scores array i.e. 4 as there are 4 elements in scores array 70,20,35,15
So the statement becomes:
scores[4] = 40;
This assigns value 40 to the 4th index of the scores array. Do not confuse 4th index with 4th element of the array because array element location starts from 0. So scores[4] does not mean 4th element but scores[4] means 4th index position of scores array. This makes 5th element of scores. So set the element 40 as 5th element at 4th index of scores.
alert("The scores array: " + scores);
This displays an alert box with the following message:
The scores array: 70,20,35,15,40

Better Design Furniture has imported three refurbished medium sized electricity generators. The manager, Sam, was advised that the maximum running time for each generator is eight (8) hours. This is ideal for the company because the plant has to run for a complete twenty four hour period. With three generators running for eight hours each, this equates to twenty four (24) hours. Sam is now in dire need of a circuit that will start-up and shutdown each generator at different eight hour intervals.
According to Sam, the generators should work as follows: • Generator A 12:00 AM - 8:00 AM
• Generator B 8:00 AM - 4:00 PM • Generator C 4:00 PM - 12:00 AM
Sam has recruited your group as interns with the responsibility of designing the system that will execute the above functions. In designing the system, the group should ensure that generators are not allowed to run simultaneously, as this will result in serious damages to Sam’s equipment. In addition, there should be a disable switch which disables the power coming from the generators and enables the use of the Jamaica Public Service’s electric to power the equipment. This is necessary for the technicians to service the generators.
