If there are m sorted arrays each with n elements, and you want to combine them into a single sorted array with mn elements you do this by merging the first two arrays, next with the third, then with the fourth, until the end with the last one, the time complexity of this algorithm in terms of m and n is O(mn log m).
When there are m sorted arrays and each array has n elements, the time complexity of the merge operation is O(n*log n). To merge m sorted arrays, the merge operation must be repeated log m times, resulting in a time complexity of O(mn*log m). Thus, the time complexity of the algorithm, in terms of m and n, is O(mn*log m).
Hence, when you have m sorted arrays, each with n elements, and you want to combine them into a single sorted array with mn elements by merging the first two arrays, next with the third, then with the fourth, until the end with the last one, the time complexity of this algorithm in terms of m and n is O(mn*log m).

The algorithm described, where the m sorted arrays are merged one by one into a single sorted array, has a time complexity of O(mn log n).
In each merge step, when merging two sorted arrays of size n, the time complexity is O(n). As there are m-1 merge steps required to combine all m arrays, the total time complexity for the merging step would be (m-1) * O(n).
However, in each merge step, the size of the arrays being merged increases. Initially, when merging the first two arrays, the size is n. In the second merge step, the size of the arrays being merged is 2n. In the third merge step, it is 3n, and so on. In the last merge step, the size is mn.
To merge arrays of different sizes, the merge operation takes O(k) time, where k is the size of the combined arrays. Therefore, in each merge step, the time complexity is proportional to the total size of the merged arrays.
The total size of the merged array is mn, and the time complexity for each merge step is O(k), where k varies from n to mn. Therefore, the overall time complexity of the algorithm is O(mn log n).
It's worth noting that if the arrays are already sorted, there are more efficient algorithms available, such as using a heap or priority queue, which can achieve a time complexity of O(mn log m) or even O(mn log(mn)).

Input a grade level (Freshman, Sophomore, Junior, or Senior) and print the corresponding grade number [9-12]. If it is not one of those grade levels, print Not in High School.
Hint: Since this lesson uses else-if statements, remember to use at least one else-if statement in your answer to receive full credit
Sample Run 1
What year of high school are you in? Freshman
Sample Output 1
You are in grade: 9
Sample Run 2
What year of high school are you in?
Kindergarten
Sample Output 2
Not in High School
Answer:
print("What year of high school are you in?")
grade = input()
grade = grade.lower()
if grade == "freshman":
print("You are in grade: 9")
elif grade == "sophomore":
print("You are in grade: 10")
elif grade == "junior":
print("You are in grade: 11")
elif grade == "senior":
print("You are in grade: 12")
else:
print("Not in high school")
Explanation:
The first line prints the question. "grade = input()" stores the answer the user will type in the terminal into the variable 'grade'.
grade.lower():
The third line lowercases the entire string ("FreshMan" would turn to "freshman"). Python is case-sensitive.
Then, test the string to see if it matches freshman, sophomore, junior, or senior. If the input string matches print the statement inside the if block. The last statement is the else. It prints if nothing else matches.

Consider the implementation of Dijkstra's algorithm in an SDN framework. Which of the following statements are true? (Hint: more than one statement is true.) a When executing, Dijkstra's algorithm will run as a network control application "on top on the SDN controller. b If a router's forwarding table should be changed as a result of running Dijkstra's algorithm, the new flow table for that router will be updated by the SDN controller via the southbound API using the Openflow protocol.
c When executing, Dijkstra's algorithm will need to send messages to all of the routers to gather their link costs.
d If a router's forwarding table should be changed as a result of running Dijkstra's algorithm, the implementation of Dijkstra's algorithm will determine the routers needing updated flow tables, and send the new flow tables to them directly using the OSPF protocol. e When executing, Dijkstra's algorithm will execute within the operating system of the SDN controller f When executing, Dijkstra's algorithm will use the link-state database that is maintained within the SDN controller.
The true statements regarding the implementation of Dijkstra's algorithm in an SDN framework are:
a) When executing, Dijkstra's algorithm will run as a network control application "on top on the SDN controller." This means that Dijkstra's algorithm is implemented as a software application that operates within the SDN controller, utilizing its capabilities for network control and management.
b) If a router's forwarding table should be changed as a result of running Dijkstra's algorithm, the new flow table for that router will be updated by the SDN controller via the southbound API using the OpenFlow protocol. This statement highlights the role of the SDN controller in updating the forwarding tables of routers based on the output of Dijkstra's algorithm.
c) When executing, Dijkstra's algorithm will need to send messages to all of the routers to gather their link costs. This step is essential for Dijkstra's algorithm to gather information about the link costs in the network, which is necessary for determining the shortest paths.

[4] b.A sequential data file called "Record.txt" has stored data under the field heading RollNo., Name, Gender, English, Nepali Maths and Computer. Write a program to display all the information of male
students whose obtained marks in computer is more than 90.
Answer:
Explanation:
Assuming that the data in the "Record.txt" file is stored in the following format:
RollNo. Name Gender English Nepali Maths Computer
101 John M 80 85 90 95
102 Jane F 85 80 75 92
103 David M 90 95 85 89
104 Mary F 75 90 80 94
105 Peter M 95 85 90 98
Here is a Python program that reads the data from the file and displays the information of male students whose obtained marks in computer is more than 90:
# Open the Record.txt file for reading
with open("Record.txt", "r") as file:
# Read the file line by line
for line in file:
# Split the line into fields
fields = line.strip().split()
# Check if the student is male and has obtained more than 90 marks in Computer
if fields[2] == "M" and int(fields[6]) > 90:
# Display the student's information
print("RollNo.:", fields[0])
print("Name:", fields[1])
print("Gender:", fields[2])
print("English:", fields[3])
print("Nepali:", fields[4])
print("Maths:", fields[5])
print("Computer:", fields[6])
print()
This program reads each line of the "Record.txt" file and splits it into fields. It then checks if the student is male and has obtained more than 90 marks in Computer. If so, it displays the student's information on the console.
The program to display all the information of male students whose obtained marks in computer is more than 90. is in the explanation part.
What is programming?Computer programming is the process of performing specific computations, typically through the design and development of executable computer programmes.
Assuming that the data in the "Record.txt" file is structured in a specific format and separated by commas, here is an example Python programme that reads the data from the file and displays information about male students who received more than 90 points in Computer:
# Open the file for reading
with open('Record.txt', 'r') as f:
# Read each line of the file
for line in f:
# Split the line by commas
data = line.split(',')
# Check if the student is male and has obtained more than 90 marks in Computer
if data[2] == 'M' and int(data[6]) > 90:
# Display the information of the student
print(f"Roll No.: {data[0]}\nName: {data[1]}\nGender: {data[2]}\nEnglish: {data[3]}\nNepali: {data[4]}\nMaths: {data[5]}\nComputer: {data[6]}\n")
Thus, in this program, we use the open() function to open the "Record.txt" file for reading.

Answer:
File Transfer Protocol (FTP) is a standard communication protocol for transferring computer files from a server on a computer network to a client. FTP is built on a client-server model architecture that uses separate control and data connections between client and server. FTP users can authenticate themselves with a clear text login protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. FTP is usually secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP) for secure transfer that protects username and password and encrypts content.
Hackerrank busy intersection. There is a busy intersection between two one-way streets: main street and first avenue
The Hackerrank Busy Intersection problem is a programming challenge that involves analyzing and comparing the flow of traffic on two one-way streets: Main Street and First Avenue. The goal is to determine the busiest time period at the intersection between these two streets.
To solve this problem, you need to first create an array to hold the number of cars that pass through the intersection during each time period. Then, you need to iterate through the array and compare the number of cars on Main Street to the number of cars on First Avenue. If the number of cars on Main Street is greater than the number of cars on First Avenue during a particular time period, then that time period is considered to be the busiest.
Once you have determined the busiest time period, you can return the start and end times of that period as your answer. Here is an example of how to solve this problem using Python:
```
def busyIntersection(mainStreet, firstAvenue):
# Create an array to hold the number of cars during each time period
traffic = [0] * 24
# Iterate through the array and compare the number of cars on Main Street to the number of cars on First Avenue
for i in range(24):
if mainStreet[i] > firstAvenue[i]:
traffic[i] = mainStreet[i]
else:
traffic[i] = firstAvenue[i]
# Find the busiest time period
