The kind of RAM made of cells consisting of SR flip-flops is Static Random Access Memory (SRAM). SRAM uses a flip-flop circuitry to store each bit of data, providing faster access times but requiring more space compared to other types of RAM.
The kind of RAM that stores data by charging and discharging capacitors is Dynamic Random Access Memory (DRAM). DRAM utilizes a capacitor to store each bit of data, requiring periodic refreshing to maintain the stored information. DRAM offers higher density at a lower cost but has slower access times compared to SRAM.
The kind of RAM that requires refreshing to operate normally is Dynamic Random Access Memory (DRAM). As mentioned earlier, DRAM cells store data in capacitors, which gradually lose charge over time. To prevent data loss, DRAM requires refreshing operations to restore the charge in the capacitors. This refreshing process is essential for the normal operation of DRAM.

Designing a Secure Authentication Protocol for a One-to-One Secure Messaging Platform (Marks: 10) (a) Analysing the security strength of authentication protocols (Marks: 7.5) Assume that you have been hired to design a secure mutual authentication and key establishment protocol for a new messaging software. In the software, two users (ex: Alice and Bob) needs to exchange messages using a public-key cryptography based authentication protocol to achieve mutual authentication and establish a secure session key (K) before the start of the conversation as shown in Figure-3. According to the given scenario, Alice and Bob should exchange three messages to achieve mutual authentication and establish the secure session key (K). Assume that Alice is the initiator of the communication. Alice sends "Message 1" to Bob and Bob replies with "Message 2". Message 1 Message 2 2 RE Alice Bob Figure-3: Overview of the secure mutual authentication and key establishment protocol You have options to choose from several protocols and analyzing their security strength. The prospective security protocols are as follows: Page 9 of 15 UNIVERSITY i. In protocol-1, Message 1: {"Alice", K, Ra}so, Message 2: RAR ii. In protocol-2, Message 1: "Alice", {K, RA}Bob, Message 2: RA, {R}Alice lii. In protocol-3, Message 1: "Alice", {K}Bob, [RA]Alice, Message 2: R4 [Re]Bob iv. In protocol-4, Message 1: Ra {"Alice", K}aab, [Ra]alice, Message 2: [Ra]scb, {Re}alice v. In protocol-5,Message 1: {"Alice", K, RA, Re}&cb, Message 2: RA, {R} Alice In this task, you need to critically analyze the above protocols and clearly explain which protocol or protocols would be secured and why. Notations are summarized below: K : Session key RA : Nonce generated by Alice : Nonce generated by Bob {"Message"}Alice : Encryption Function that encrypts "Message using Alice's public Key ["Message"]Alice : Encryption Function that encrypts "Message" using Alice's private Key which is also known as signed "Message" by Alice [Note: Refer to the Week 9 lecture and Workshop 9.] Re
In analyzing the security strength of the given authentication protocols for the one-to-one secure messaging platform, we need to evaluate their effectiveness in achieving mutual authentication and establishing a secure session key.
Protocol-1: Message 1: {"Alice", K, Ra}so, Message 2: RAR
Protocol-2: Message 1: "Alice", {K, RA}Bob, Message 2: RA, {R}Alice
Protocol-3: Message 1: "Alice", {K}Bob, [RA]Alice, Message 2: R4 [Re]Bob
Protocol-4: Message 1: Ra {"Alice", K}aab, [Ra]alice, Message 2: [Ra]scb, {Re}alice
Protocol-5: Message 1: {"Alice", K, RA, Re}&cb, Message 2: RA, {R} Alice
To determine which protocol or protocols are secure, we need to consider the following criteria:
Mutual Authentication: The protocol should ensure that both Alice and Bob can verify each other's identities.
Session Key Establishment: The protocol should establish a secure session key between Alice and Bob.
Protection against Replay Attacks: The protocol should prevent an attacker from replaying previously captured messages.
Resistance to Eavesdropping: The protocol should protect the confidentiality of the exchanged messages.
By analyzing the protocols based on these criteria and the provided information, it is difficult to determine the specific security properties of each protocol without further details or cryptographic analysis. Each protocol seems to have variations in message format and the inclusion of nonces and encryption.

Construct a binary search tree, find which value is the median
value, and delete that value.
A binary search tree is a data structure that is frequently used to search for and store ordered information. It is a type of binary tree that has the following properties: The left subtree of a node contains only nodes with keys less than the node's key.
The right subtree of a node contains only nodes with keys greater than the node's key. The left and right subtrees are both binary search trees in and of themselves.
A node with no children is referred to as a leaf node, while a node with children is referred to as an internal node.
To begin, a binary search tree must be constructed. The binary search tree can be constructed in a number of ways.
However, the basic rule of construction is that each node's value should be less than the value of its right child and greater than the value of its left child, if one exists.
Let's say that the binary search tree is constructed and we now need to determine the median value and delete it.
We will use the following procedure to identify the median value:
If the number of nodes in the binary search tree is odd, the median value will be the middle node. If the number of nodes is even, the median value will be the average of the two middle nodes' values.
Once the median value has been identified, it can be deleted by making use of the deletion method.
The value to be deleted can be found in the binary search tree by comparing the values of the nodes and, based on the comparison, traversing the left or right subtree to get to the desired node.
Once the node is located, it can be deleted from the binary search tree by considering the following three cases:
Case 1: If the node being deleted has no children, it is simply deleted from the binary search tree.
Case 2: If the node being deleted has one child, the child takes its place in the binary search tree.
Case 3: If the node being deleted has two children, the minimum value in the right subtree takes its place in the binary search tree.

for any physical network, the value of e th can be determined experimentally by measuring the open-circuit voltage across the load terminals.
For any physical network, the value of e_th (Thevenin voltage) can be determined experimentally by measuring the open-circuit voltage across the load terminals.
The Thevenin theorem is a useful concept in electrical circuit analysis, which states that any linear network consisting of voltage and current sources and resistors can be represented by an equivalent circuit containing a single voltage source (e_th) in series with a single resistor (R_th).
To determine the value of e_th experimentally, follow these steps:
1. Disconnect the load (resistor) from the network terminals.
2. Measure the voltage across the open terminals where the load was connected. This measured voltage is the open-circuit voltage, which is equivalent to e_th.
3. Record the value of the measured open-circuit voltage.
The value obtained through this experimental measurement represents the Thevenin voltage (e_th) of the network under consideration.
The Thevenin voltage (e_th) of a physical network can be determined experimentally by measuring the open-circuit voltage across the load terminals. This value represents the voltage that would be supplied by the equivalent Thevenin circuit when the load is disconnected. By knowing the Thevenin voltage and resistance, we can simplify complex networks and analyze the behavior of a network when connected to various loads. Experimental determination of e_th allows for practical implementation and analysis of real-world circuits, aiding in circuit design, troubleshooting, and optimization.

1. Is a there a PN junction in a Gunn diode?
2. What is the difference between a TED and an IMPATT?
3. Sketch the Gunn diode construction?
4. What is the approximate buffer thickness in the Gunn diode?
5. Sketch a diagram showing how a Gunn diode is mounted inside a WR90 cavity including the low pass choke filter?
6. What is the function of the low pass choke?
A Gunn diode consists of a PN junction, operates based on different principles from TED and IMPATT diodes, has a specific construction with a high-resistivity layer, has an approximate buffer thickness, and is mounted in a cavity with a low pass choke filter to suppress high-frequency noise.
What are the key aspects of a Gunn diode?1. Yes, there is a PN junction in a Gunn diode. However, unlike traditional PN junction diodes, the PN junction in a Gunn diode is not used for rectification or as a junction for forward and reverse biasing.
2. The main difference between a TED (Transferred Electron Device) and an IMPATT (Impact Avalanche Transit Time) diode lies in their operating principles. A TED operates based on the transferred electron effect, while an IMPATT diode operates based on the impact ionization process.
3. The construction of a Gunn diode typically consists of a semiconductor material, such as Gallium Arsenide (GaAs), with a high-resistivity layer sandwiched between two low-resistivity layers. This creates a diode structure where the middle layer acts as the active region for the Gunn effect to occur.
4. The approximate buffer thickness in a Gunn diode depends on the specific design and material properties. Generally, it ranges from a few micrometers to tens of micrometers.
5. A diagram showing the mounting of a Gunn diode inside a WR90 cavity includes the positioning of the diode in the center of the cavity, with appropriate electrical connections. The low pass choke filter is typically connected in series with the output of the Gunn diode and is designed to allow the desired frequency range to pass while attenuating higher frequencies.
6. The function of the low pass choke filter in a Gunn diode circuit is to suppress or attenuate high-frequency components and prevent them from interfering with the desired low-frequency signals. It helps to improve the purity and stability of the output signal by filtering out unwanted high-frequency noise or harmonics.

Q4. As a graphic designer you are expected to convert window to viewport transformation with the given values. for window, \( X \) wmin \( =20, X \) wax \( =80, Y \), \( \min =40, Y \) wmax \( = \) 80
To convert window to viewport transformation with the given values, the following steps can be taken:
1. Determine the window and viewport dimensions.
2. Use the formula to calculate the viewport coordinates.
In graphic design, the process of converting window to viewport transformation involves mapping the coordinates of objects from a specified window space to a viewport space. The given values, \( X \) wmin \( = 20, X \) wmax \( = 80, Y \) wmin \( = 40, \) and \( Y \) wmax \( = 80 \), represent the minimum and maximum coordinates of the window in the X and Y axes, respectively.
Step 1: Determining the window and viewport dimensions
The window dimensions can be calculated by finding the differences between the maximum and minimum values in each axis. In this case, the width of the window (Ww) is 80 - 20 = 60 units, and the height of the window (Hw) is 80 - 40 = 40 units.
Step 2: Calculating the viewport coordinates
To convert the window coordinates to viewport coordinates, a formula can be used:
\( Xv = (Xw - X \) wmin \( ) \times (Wv / Ww) + X \) vmin
\( Yv = (Yw - Y \) wmin \( ) \times (Hv / Hw) + Y \) vmin
Where:
- \( Xv \) and \( Yv \) represent the converted viewport coordinates.
- \( Xw \) and \( Yw \) are the window coordinates.
- \( X \) wmin and \( Y \) wmin represent the minimum values of the window.
- \( Wv \) and \( Hv \) are the viewport dimensions.
- \( X \) vmin and \( Y \) vmin represent the minimum values of the viewport.
The above formula calculates the corresponding viewport coordinates by scaling and translating the window coordinates based on the dimensions of the viewport. It ensures that objects maintain their relative positions and proportions when displayed in the viewport.

Write a program that generates a random number between 0 and 50 , and let the user guess what number you generate, the user has only three questions to ask following the next format: - Is it greater t
The program is designed to generate a random number between 0 and 50 and allow the user to guess the generated number. The user is given three questions to ask in order to narrow down their guess.
To implement this program in Python, we can use the `random` module to generate a random number within the specified range. The program will prompt the user to enter their guess and then provide feedback based on the guess.
Here is an example of how the program can be implemented:
```python
import random
# Generate a random number between 0 and 50
number = random.randint(0, 50)
# Prompt the user to guess the number
print("Guess the number between 0 and 50")
guesses = 0
# Allow the user to ask three questions
while guesses < 3:
guess = int(input("Enter your guess: "))
# Compare the guess with the generated number
if guess == number:
print("Congratulations! You guessed the correct number.")
break
elif guess < number:
print("The number is greater than your guess.")
else:
print("The number is smaller than your guess.")
guesses += 1
if guesses == 3:
print("You have used all your questions. The number was", number)
```
This program generates a random number and allows the user to guess it using a limited number of questions. The program provides feedback based on the user's guesses and informs them whether the number is greater or smaller. If the user exhausts all three questions without guessing correctly, the program reveals the generated number.

If any other time outside the range 0-24 is given, you want to print "That's not a valid time!". You come up with the following snippet: if time < 12: print("Good Morning!") if time 17: print("Good Afternoon!")
elif time < 23: print("Good Night!") else: print("That's not a valid time!") Which of the following is true? Multiple statements will be printed for all values of time
Only a single statement will be printed for all values of time When time = 23.5, the incorrect statement is printed
When time = 5, multiple statements will be printed
The code snippet will only print a single statement for each value of time. It checks the conditions in a sequential manner and executes the first condition that evaluates to True.
Based on the given code snippet:
python
Copy code
if time < 12:
print("Good Morning!")
if time >= 12 and time < 17:
print("Good Afternoon!")
elif time >= 17 and time < 24:
print("Good Night!")
else:
print("That's not a valid time!")
Explanation:
The code uses conditional statements (if, elif, and else) to determine which statement to print based on the value of time.
If time is less than 12, the condition time < 12 is satisfied, and the statement "Good Morning!" is printed.
If time is between 12 and 16 (inclusive), the condition time >= 12 and time < 17 is satisfied, and the statement "Good Afternoon!" is printed.
If time is between 17 (inclusive) and 24 (exclusive), the condition time >= 17 and time < 24 is satisfied, and the statement "Good Night!" is printed.
If time is outside the range of 0-24, none of the previous conditions are satisfied, and the statement "That's not a valid time!" is printed.
The code snippet will only print a single statement for each value of time. It checks the conditions in a sequential manner and executes the first condition that evaluates to True. Therefore, only one statement will be printed based on the value of time. When time is 23.5, the correct statement "Good Night!" will be printed.

In this program, the `splitArray` function takes the array `arr`, its size `n`, the number of subarrays `m`, and the size of each subarray `k` as parameters. It first checks if `n` is divisible by `m`. If not, it prints an error message. Otherwise, it iterates over the array and prints each subarray by indexing the appropriate elements based on `m` and `k`. The `main` function takes user input for the array and the parameters, and then calls the `splitArray` function.
Please note that this program assumes valid input and doesn't include extensive error handling. You can modify it according to your specific requirements.

To create a program that implements a linked list assigns values, prints a range of values, and eliminates duplicate numbers, you can follow these steps:
1. Define a struct to represent the nodes of the linked list. Each node should contain an integer value and a pointer to the next node.
2. Create a function to insert values into the linked list. This function should dynamically allocate memory for new nodes and link them together.
3. Implement a function to print a range of values in the linked list. Iterate through the list, starting from the head, and print the values within the specified range.
4. Write a function to eliminate duplicate numbers from the linked list. Traverse the list and compare each value with the rest of the list. If a duplicate is found, remove that node from the list.
5. In the main program, create a linked list, assign values to it, print the desired range of values, and then eliminate duplicates using the defined functions.

In the given code snippet, we define a class named[tex]`mainWindow`[/tex] that inherits from the[tex]`QMainWindow`[/tex] class provided by PyQt5. This class represents the main window of the application.
To proceed with the Sprint 2 code implementation, we need to define the initialization method (`__init__`) for the[tex]`mainWindow`[/tex]class. Inside this method, we can add the specific code related to Sprint 2.
The `__init__` method is a special method that is automatically called when an instance of the[tex]`mainWindow`[/tex] class is created. By calling `super().__init__()`, we ensure that the initialization method of the base class ([tex]`QMainWindow`[/tex]) is also executed before our custom code.
To implement the Sprint 2 functionality, you can add your code within the `__init__` method. This may include creating and configuring widgets, setting up layouts, connecting signals and slots, or any other tasks specific to Sprint 2 requirements.
By following this structure, you can extend the [tex]`mainWindow`[/tex]class with the necessary functionality for Sprint 2.

To implement and use a queue, the goal of this assignment is to be accomplished. A queue will be implemented using the fra. The answer to the question MUST run on replit. Don't copy other answers. Queues will be explained here in 100 words only.A queue is a linear data structure that follows the First In First Out(FIFO) principle.
A queue is used to store a set of elements, such as integers or characters. When a new element is added to a queue, it is added to the end of the queue. When an element is removed from the queue, it is removed from the front of the queue.A queue has two primary operations: enqueue and dequeue. The enqueue operation adds a new element to the end of the queue. The dequeue operation removes an element from the front of the queue.A queue can be implemented using an array or a linked list. When using an array, a front and rear pointer are used to keep track of the elements in the queue. When using a linked list, a front pointer is used to keep track of the first element in the queue, and a rear pointer is used to keep track of the last element in the queue.A queue is a fundamental data structure used in computer science and programming. It is used in many applications, such as operating systems, computer networks, and simulations.

Your first task is to design a data structure that can be used to store which busses already arrived, print the list of available buses that needs to get the service and be prepared to dispatch again.
To store which buses have already arrived, the most appropriate data structure would be a set. This is because a set only stores unique elements, which means that if a bus has already arrived and is stored in the set, it won't be duplicated.
A set can also easily be used to find the available buses that need to get the service. By subtracting the set of arrived buses from the set of all buses, we can obtain the set of available buses that still need to get the service.In terms of dispatching the buses, a queue data structure would be most appropriate. This is because a queue follows the "first in, first out" (FIFO) principle, which means that the first bus that needs to be dispatched will be the first bus in the queue to be processed.

Given the two helper APIs, an algorithm that can make product suggestions for a user can be made. These suggestions will be based on the products that the user has.
The given Java code demonstrates an example algorithm for product suggestions in Java:
public List suggestProducts(List userProducts, HelperAPI api1, HelperAPI api2) {
List suggestedProducts = new ArrayList<>();
Map productFrequencyMap = new HashMap<>();
// Count frequency of products in userProducts
for (String product : userProducts) {
productFrequencyMap.put(product, productFrequencyMap.getOrDefault(product, 0) + 1);
}
// Iterate through all products in both APIs
for (String product : api1.getAllProducts()) {
if (!userProducts.contains(product)) { // Only suggest products not already owned by user
int frequency = productFrequencyMap.getOrDefault(product, 0);
if (frequency > 0) { // User has purchased similar products, so suggest this one
suggestedProducts.add(product);
} else { // User has not purchased similar products, so suggest if frequently bought by other users
int api1Frequency = api1.getFrequency(product);
int api2Frequency = api2.getFrequency(product);
if (api1Frequency + api2Frequency > 10) { // If product is frequently bought by other users
suggestedProducts.add(product);

return suggestedProducts;
}
The given Java code uses two helper APIs to suggest products to a user based on the products they have already purchased.
The code uses a map to count the frequency of products in the user's purchase history and then iterates through all products in both APIs to suggest products that are either similar to the ones the user has purchased or frequently bought by other users.

A majority circuit is a combinational circuit whose output is equal to 1 if the inputs have more 1’s than 0’s. Otherwise, the output is 0. Design a 5-input majority circuit as a minimal two-level circuit. Schematic is not required.
To design a 5-input majority circuit as a minimal two-level circuit, we can use a combination of AND and OR gates.
A majority circuit checks if the inputs have more 1's than 0's and outputs 1 if that condition is met. In this case, we have 5 inputs, so we need to ensure that there are at least 3 inputs with a logic value of 1 to satisfy the majority condition.
To achieve this, we can connect the 5 inputs to an AND gate to detect when all 5 inputs are 1. This will output a 1 only if all the inputs are 1. Next, we connect each input to an OR gate individually. This ensures that even if only one of the inputs is 1, the OR gate will output a 1. Finally, we connect the output of the AND gate and the outputs of the OR gates to another OR gate. This final OR gate will output a 1 if the majority condition is met (i.e., at least 3 inputs are 1).
By using this combination of AND and OR gates, we can design a minimal two-level circuit for the 5-input majority circuit. The AND gate serves as the first level, checking for all 5 inputs being 1, and the OR gates form the second level, detecting individual 1's in the inputs. This design ensures that the circuit produces the desired output of 1 when the majority condition is satisfied and 0 otherwise.

Write a function transform() which takes a single argument word in the form of a non-empty string consisting of lowercase alphabetical symbols only, and returns its 4-character encoded form. This encoded form retains the first character of word and transforms the rest of the string according to the following rules: 1. All vowels and the consonants 'w', 'h', and 'y' are replaced with the number 'o'. All other consonants are grouped based on their phonetic similarity and each group is assigned to a numeric code. The following CODES constant is a list that provides these groups. The number for each group is the corresponding index in the list: CODES = ['a, e, i, o, u, y, h, w', 'b, f, p, v', 'c, g, j, k, q, s, x, z', 'd, t', '2', 'm, n', 'r'] 2. Duplicates are removed. All adjacent instances of the same number are replaced with a single instance of that number). 3. All zeroes ('0') are removed. 4. The resulting string is truncated to 4 characters. One or more trailing zeros are added if the string is shorter than 4 characters. For example, 'alice' would first be transformed into 'a4020' (step 1); there are no duplicates to remove (step 2); after removing zeros it becomes 'a42' (step 3); as the string is shorter than 4 characters, we append 'o' to get 4 characters exactly (step 4) and the final form 'a420' is returned. Example calls to the function are: >>> transform("robert") 'r163' >>> transform("ruppert") 'r163' >>> transform("roubart") 'r163' >>> transform("hobart") 'h163' >>> transform("people") 'p140' >>> transform ("peeeeeeeeeeooopppppplee") 'p140'
The transform() function takes a word as input and returns its 4-character encoded form based on specific rules.
The transform() function takes a word and performs the following steps to generate its encoded form:
Replace vowels and the consonants 'w', 'h', and 'y' with 'o'.
Group remaining consonants based on their phonetic similarity using CODES constant.
Remove duplicates and adjacent instances of the same number.
Remove all zeros ('0').
Truncate the resulting string to 4 characters.
If the string is shorter than 4 characters, add trailing zeros.
Return the final encoded form of the word.
The examples provided demonstrate how the transform() function works and the expected output for different input words.

assuming that nothing else changes, which one of the following is a correct statement concerning the relationship between the variables in present value and future value?
The relationship between present value (PV) and future value (FV) can be described by the following statement: As the present value increases, the future value also increases.
The present value represents the current worth or value of an asset or investment, while the future value represents the value of that asset or investment at a specified future date, taking into account factors such as interest or growth. When the present value increases, it means that more funds are being allocated or invested upfront, which allows for potential growth or returns over time. Consequently, this higher initial value contributes to a higher future value, reflecting the compounded effect of interest or growth over the given time period.

The purpose of the double-headed arrow (white) as pointed to by the red arrow is to select all fields from the table in the design of Query1.
When designing a query in a database, the double-headed arrow is used to select all fields from a table. This means that all the columns in the table will be included in the query's result set. For example, let's say we have a table called "Students" with columns like "Name," "Age," and "Grade." If we use the double-headed arrow in the design of Query1, it means that the query will retrieve all the information from these columns for each student in the "Students" table.
So, in this case, selecting the double-headed arrow (white) as pointed to by the red arrow would indeed select all fields from the table in the design of Query1.

Write recursive merge sort code in Haskell.
firstHalf :: [Char] -> [Char]
firstHalf cs = take (ceiling (fromIntegral (length cs) / 2)) cs
a) Adapt the firstHalf code from the lecture example to work with a list of values of any data type (that is, change the type signature from [Char] -> [Char] to [a] ->[a])
b) Add a function just like the one from a) except that it returns the second half of the list.
c) Write a merge function that merges two lists, xs and ys:
If either list has length 0, just return xs ++ ys. Otherwise,
if the first value in xs is less than or equal to the first value in ys, use cons to prepend the first value in xs to the result of a recursive call one the rest of xs and all of ys.
if the first value in xs is less than the first value in ys, prepend the first value in ys to the result of a recursive call on xs and the rest of ys.
Note that the data type of the items in the list must be an Ord, so the type signature will be:
merge :: Ord a => [a] -> [a] -> [a]
d) Write the function mergeSort. Consider the types for the function signature. Here is how the function should work. To mergeSort the list xs:
if the length of xs is less than 2, return xs
otherwise, call mergeSort on the first half of the list, do the same on the second half, and merge the results
Here is the recursive merge sort code in Haskell:
mergeSort :: Ord a => [a] -> [a]
mergeSort xs
| length xs < 2 = xs
| otherwise =
let firstHalf = take (length xs `div` 2) xs
secondHalf = drop (length xs `div` 2) xs
in merge (mergeSort firstHalf) (mergeSort secondHalf)
merge :: Ord a => [a] -> [a] -> [a]
merge [] ys = ys
merge xs [] = xs
merge (x:xs) (y:ys)
| x <= y = x : merge xs (y:ys)
| otherwise = y : merge (x:xs) ys
The `mergeSort` function takes a list `xs` and performs the merge sort algorithm on it. If the length of `xs` is less than 2 (i.e., it contains 0 or 1 element), it returns the list as is. Otherwise, it splits the list into two halves, `firstHalf` and `secondHalf`, using `take` and `drop` functions respectively. It then recursively applies `mergeSort` to each half and merges the sorted results using the `merge` function.
The `merge` function takes two sorted lists, `xs` and `ys`, and merges them into a single sorted list. If either list is empty, it simply returns the other list. Otherwise, it compares the first elements of both lists. If the first element of `xs` is less than or equal to the first element of `ys`, it appends the first element of `xs` to the result of recursively merging the rest of `xs` with all of `ys`. Otherwise, it appends the first element of `ys` to the result of recursively merging `xs` with the rest of `ys`.
By recursively dividing the list into smaller halves and merging them back together in a sorted manner, the `mergeSort` function effectively sorts the input list in ascending order.
