Answers
The dotted red line with * marks can be used to represent the ozone concentration, while the dotted blue line with x marks can be used to represent the standard set by the EPA in 2015.
What is ozone?Ozone is a highly reactive, toxic gas composed of three oxygen atoms. It is found both in the Earth's upper atmosphere, known as the stratosphere, and at ground level. In the stratosphere, ozone is created naturally by ultraviolet radiation, forming a layer that protects life on Earth from the Sun's harmful ultraviolet radiation. However, at ground level ozone is considered a pollutant, created by the reaction of sunlight with nitrogen oxides and volatile organic compounds. This type of ozone is known as ground-level or “bad” ozone and can cause serious health problems, such as asthma and other respiratory illnesses. It can also damage crops, trees, and other vegetation, as well as buildings and other materials. Reducing air pollution and emissions from vehicles, industry, and other sources can help to reduce the amount of ground-level ozone.
The red line will show the current ozone concentration, while the blue line will show the standard that is set. This can be used to show the changes in ozone concentrations over time and how they compare to the standard set.

Write a function called matches that takes two int arrays and their respective sizes, and returns the number of consecutive values that match between the two arrays starting at index 0. Suppose the two arrays are {3, 2, 5, 6, 1, 3} and {3, 2, 5, 2, 6, 1, 3} then the function should return 3 since the consecutive matches are for values 3, 2, and 5.
Answers
Answer:
Written in C++
int matches(int arr1[], int arr2[], int k) {
int count = 0;
int length = k;
for(int i =0; i<length; i++) {
if(arr1[i] == arr2[i]) {
count++;
}
}
return count;
}
Explanation:
This line defines the function
int matches(int arr1[], int arr2[], int k) {
This line initializes count to 0
int count = 0;
This line initializes length to k
int length = k;
This line iterates through the array
for(int i =0; i<length; i++) {
The following if statement checks for matches
if(arr1[i] == arr2[i]) {
count++;
}
}
This returns the number of matches
return count;

Fill in the blank to complete the “even_numbers” function. This function should use a list comprehension to create a list of even numbers using a conditional if statement with the modulo operator to test for numbers evenly divisible by 2. The function receives two variables and should return the list of even numbers that occur between the “first” and “last” variables exclusively (meaning don’t modify the default behavior of the range to exclude the “end” value in the range). For example, even_numbers(2, 7) should return [2, 4, 6].
def even_numbers(first, last):
return [ ___ ]
print(even_numbers(4, 14)) # Should print [4, 6, 8, 10, 12]

Answers

Write a short note on Python functions.In Python, a function is a block of code that can perform a specific task. It is defined using the def keyword followed by the function name, parentheses, and a colon. The function body is indented and contains the code to perform the task.
Functions can take parameters, which are values passed to the function for it to work on, and can return values, which are the result of the function's work. The return keyword is used to return a value from a function.
Functions can be called by their name and passed arguments if required. They can be defined in any part of the code and can be called from anywhere in the code, making them reusable and modular.
Functions can make the code more organized, easier to read, and simpler to maintain. They are also an essential part of object-oriented programming, where functions are known as methods, and they are attached to objects.

Write a program that will filter a list of non-negative integers such that all duplicate values are removed. Integer values will come from standard input (the keyboard) and will range in value from 0 up to 2,000,000,000. Input will be terminated by the special value, -1. Once the input is read in you should output (to the screen) the list of numbers as a sorted list (smallest to largest) with one value listed per line where all duplicates have been removed. The primary difficulty with this program is that there are an enormous number of input values and an expected large number of duplicate numbers.
Answers
Answer:
The program in python is as follows:
original = []
inp = int(input(": "))
while inp>=0:
if inp<=2000000000:
original.append(inp)
inp = int(input(": "))
newlist = []
for i in original:
if i not in newlist:
newlist.append(i)
newlist.sort()
for i in newlist:
print(i)
Explanation:
This initializes the original list
original = []
This gets input for the list
inp = int(input(": "))
The following loop is repeated while input is not negative
while inp>=0:
This ensures that only inputs from 0 and 2000000000 enters the list
if inp<=2000000000:
original.append(inp)
Prompt the user for another input
inp = int(input(": "))
This initializes a newlist
newlist = []
Iterates through the original list
for i in original:
Check for duplicate
if i not in newlist:
Each number is entered to the new list, without duplicate
newlist.append(i)
This sorts the new list in ascending order
newlist.sort()
This prints the list item one per line
for i in newlist:

Show the contents of the queue after all operations have been performed and indicate where the front and end of the queue are. Describe in pseudo-code a linear-time algorithm for reversing a queue Q.

Answers
Reversing a queue Q in linear time: ReverseQueue(Q): stack = []; while Q: stack.append(Q.pop(0)); while stack: Q.append(stack.pop()).
After performing the given operations on the initially empty queue, the contents of the queue and the positions of the front and end of the queue are as follows:
Contents of queue: T Z 1 A G A R F
Front of queue: points to the element 'T'
End of queue: points to the element 'F'
To reverse a queue Q in linear time, we can use a stack as an auxiliary data structure. The algorithm will work as follows:
Create an empty stack S.Dequeue each element from the queue Q and push it onto the stack S.Once all elements have been pushed onto the stack S, pop each element from the stack S and enqueue it back onto the queue Q.The elements of the queue Q are now in reversed order.Pseudo-code for the algorithm is as follows:
reverseQueue(Q):
create a stack S
while Q is not empty:
x = dequeue(Q)
push(S, x)
while S is not empty:
x = pop(S)
enqueue(Q, x)
This algorithm reverses the order of the elements in the queue in linear time O(n), where n is the number of elements in the queue.

What is an example of an absolute cell reference? 52% D2 $B$5 !90!
Answers
Answer:
$B$5 is an example of absolute cell reference
Explanation:
There are two types of referencing in MS Excel.
1. Relative
2. Absolute
Relative cell referencing changes according to the corresponding new cells when it is copied in other cells. MS Excel uses relative cell referencing by default.
Absolute cell referencing uses dollar sign with the row number and column name. When any formula with absolute referencing is copied, the cell addresses used remain the same.
From the given choices in question,
$B$5 is an example of absolute cell reference
An example of an absolute cell reference is "$B$5".
Thus, option (C) is correct.
Cell references can be either relative or absolute.
A relative cell reference changes when it is copied to another cell.
For example, if you have a formula in cell C2 that references cell A2 as "=A2+1", and you copy this formula to cell C3, it will automatically adjust to "=A3+1".
An absolute cell reference remains constant, regardless of where it is copied. When a cell reference is made absolute, the dollar sign ($) is used to indicate this.
For example, if you have a formula in cell C2 that references cell B5 as "=B$5+1", and you copy this formula to cell D3, it will still refer to cell B5 as "=B$5+1". The row and column references remain fixed.
Therefore, "$B$5" is an absolute cell reference.
Thus, option (C) is correct.
