A)Factorial is defined as: fact(n) = { 1, if n = 0 n ∗ fact(n − 1), otherwise Unfold the evaluation of fact(5) on paper, and then implement it in Idris and confirm that Idris also computes the same value.
B)Re-write the factorial function to generate an iterative process. Hint: The type is fact_iter : Nat -> Nat -> Nat and you should pattern match against (S Z) acc (number 1, and accumulator) and (S n) acc (successor, and accumulator)
Answers
In the factorial function, factorials of numbers are calculated using recursion. The recursive formula is given by fact(n) = { 1, if n = 0 n ∗ fact(n − 1), otherwise Now, to find fact(5), we have to put n=5 in the above formula.
Therefore, fact(5) = 5 * fact(4) And to find fact(4), we have to put n=4 in the above formula.
Therefore, fact(4) = 4 * fact(3) And to find fact(3), we have to put n=3 in the above formula.
Therefore, fact(3) = 3 * fact(2) And to find fact(2), we have to put n=2 in the above formula.
Therefore, fact(2) = 2 * fact(1) And to find fact(1), we have to put n=1 in the above formula.
Therefore, fact(1) = 1 * fact(0) And to find fact(0), we have to put n=0 in the above formula.
Therefore, fact(0) = 1 So, fact(5) = 5 * 4 * 3 * 2 * 1 = 120
Now, the implementation of the same in Idris is given below:
fact : Nat -> Natfact Z = 1fact (S k) = (S k) * fact k
Here, Z represents zero and (S k) represents the successor of k.
We use S k instead of k+1 for the successor of k as k can be of type Nat which doesn't support the addition operation. The above implementation is equivalent to the formula fact(n) = { 1, if n = 0 n ∗ fact(n − 1), otherwiseWe can verify that the value of fact(5) obtained through the Idris implementation is same as the one obtained using the recursive formula.

Packet Transmission Delay. Consider the network shown in the below, with two senders on the left sending packets to a common receiver on the right. The links have transmission rates of R₁ R₂ = 100 Mbps (i.e.. 100 x 106 bits per second). Suppose each packet is 1 Mbit (105 bits) in size. How long does it take a sender to transmit a packet into its link (i.e., the packet transmission delay at the sender)? O 1 sec O.1 sec 01 sec O 106 msec 100 sec
Answers
The packet transmission delay at the sender is 0.01 seconds or 10 milliseconds. The packet transmission delay at the sender can be calculated by dividing the size of the packet by the transmission rate of the link.
To calculate the packet transmission delay at the sender, we divide the packet size by the transmission rate of the link.
Packet Transmission Delay = Packet Size / Transmission Rate
In this case, the packet size is 1 Mbit (105 bits) and the transmission rate is 100 Mbps (100 x 106 bits per second).
Packet Transmission Delay = 105 bits / (100 x 106 bits per second)
= 1 / (100 x 10^-2) seconds
= 1 / 100 seconds
= 0.01 seconds

(Enter your answer using interval notation.) Changed: Your submitted answer was incorrect. Your current answer has not been submitted.
Answers
Answer:
The answer to this question can be defined as follows:
Explanation:
Given value:
\(x = t^2 + 5......(1)\\\\ y = t^2 + 5t........(2)\)
To find:
\(\bold {\frac{dy}{dx} \ \ \ and\ \ \ \frac{d^2y}{dx^2} = ?}\)
Differentiate the above equation:
equation 1:
\(\frac{dx}{dt}= 2t.......(1)\\\)
equation 2:
\(\frac{dy}{dt}= 2t+5\)
Formula:
\(\frac{dy}{dx}= \frac{\frac{dy}{dt}}{\frac{dx}{dt}}\\\\\)
\(\boxed{\bold{\frac{dy}{dx}=\frac{2t+5}{2t}}}\)
To calculate the \(\bold{\frac{d^2y}{dx^2}}\) we Differentiate the above equation but before that first solve the equation:
Equation:
\(\frac{dy}{dx}=\frac{2t+5}{2t}\)
\(=\frac{2t}{2t}+\frac{5}{2t}\\\\= 1+\frac{5}{2t}\\\\=1+\frac{5}{2} t^{-1} \\\)
Formula:
\(\bold{\frac{d}{dx} \ x^n = nx^{n-1}}\)
\(\frac{dy^2}{dx^2}= 0+\frac{5}{2} (-1 t^{-2})\\\\\)
\(= -\frac{5}{2} t^{-2}\\\\= -\frac{5}{2 t^2} \\\\\)

Answer:
is a remarkably complex technical system built on the creative contributions of scientists around the world from the 1950s to the present. Throughout its evolution, the Internet and other networks have been promoted by governments, researchers, educators, and individuals as tools for meeting a range of human needs. A combination of high-level policy and grassroots improvisation has produced social benefits including easier and more widespread access to computers and information; increased scientific collaboration; economic growth; the formation of virtual communities and an increased ability to maintain social ties over long distances; the democratization of content creation; and online political and social activism. The Internet’s rapid growth has also spawned technical crises, such as congestion and a scarcity of network addresses, and social dilemmas, including malicious and illegal activities and persistent digital divides based on income, location, age, gender, and education. Such problems continue to demand creative solutions from scientists, policy makers, and citizens.
Several general themes characterize the technical development of the Internet. First, from the 1950s to the present there has been a steady increase in the size of data networks and the variety of services they offer. Rapid growth and diversity have forced network designers to overcome incompatibilities between computer systems and components, manage data traffic to avoid congestion and chaos, and reach international agreement on technical standards. These challenges have led to fundamental advances in research areas such as operating systems and queuing theory. A second trend has been the modeling of network functions as a series of layers, each of which behaves according to a standard protocol, a set of rules for interaction that is implemented in software or hardware. Layering reduces the complexity of the network system and minimizes the amount of standardization necessary, which makes it easier for networks to join the Internet. A third important feature of the Internet’s technical development has been an unusually decentralized and participatory design process. This has opened the system to innovation from a variety of directions and has encouraged informal worldwide collaboration. The following sections describe some of the major milestones in the evolution of the Internet and its predecessors.

Answers
Implementing mergesort and quicksort with median-of-three partitioning and a cutoff of 15 are both experimental studies of sorting algorithms. Both algorithms have been extensively studied and compared in terms of their performance and efficiency in sorting large data sets.
While mergesort has a high space complexity, it has a worst-case time complexity of O(n log n) which makes it efficient for sorting large data sets. On the other hand, quicksort has a lower space complexity and an average-case time complexity of O(n log n) but has a worst-case time complexity of O(n^2). By implementing median-of-three partitioning and a cutoff of 15, quicksort can be improved to reduce the worst-case scenario and perform better on small partitions.
Both MergeSort and QuickSort are efficient sorting algorithms, with MergeSort having a time complexity of O(n*log(n)) and QuickSort having an average-case time complexity of O(n*log(n)). By using the median-of-three partitioning and a cutoff, QuickSort can be further optimized for smaller partitions.

What is Initialization Vector?An Initialization Vector (IV) is a random number used in cryptography that helps to ensure the uniqueness and randomness of data used in an encryption process. The IV is typically used as part of an encryption algorithm, where it is combined with a secret key to encrypt a message. The IV is unique for each encryption session, and must be unpredictable and non-repeating. A good IV should not be reused across multiple encryption sessions, and it should be kept secret from anyone who does not have access to the decryption key. Without a good IV, a cryptographic system can be vulnerable to attacks such as replay attacks, where an attacker can gain access to the system by repeating an encrypted message.

Answers
The code segment creates a string object named str and initializes it with the value "AP". Then it concatenates the string "CS " with the values 1 and 2, resulting in the string "CS 12".
Finally, it concatenates this string to the value of str, resulting in the string "APCS 12".
When the System.out.println() method is called with the str variable as its argument, it prints the string "APCS 12" to the console.
The order of the concatenation is determined by the order of operations in Java. In this case, the + operator is evaluated from left to right, so the string "CS " is concatenated with the integer 1 to form the string "CS 1", which is then concatenated with the integer 2 to form the final string "CS 12".
It is important to note that the addition operation between a string and an integer results in a string, since the integer is implicitly converted to a string before concatenation.
