(a) Starting with an empty BST and adding the sequence of items 21, 16, 17, 4, 5, 10, 1 using the defined procedure results in an unbalanced binary search tree. The resulting tree is skewed to the right side.
(b) By constructing the same sequence of seven items in a specific order, a perfectly balanced binary tree can be achieved. The resulting tree will have the minimum possible height and optimal balance.
(c) By rearranging the sequence of the same seven items, a maximally unbalanced binary tree can be obtained. The resulting tree will have the maximum possible height and lack balance.
(a) The initial empty BST is constructed by adding elements one by one in the order of 21, 16, 17, 4, 5, 10, and 1. Following the binary search tree property, each item is inserted as a child of a parent node based on its value. In this case, the resulting tree will have a skewed right structure, as each subsequent item is greater than the previous one. The resulting BST will look like this:
21

(b) To achieve a perfectly balanced binary tree, the sequence of the same seven items can be inserted in a specific order. The order is 10, 4, 16, 1, 5, 17, and 21. By inserting them following the defined procedure, the resulting tree will have the minimum possible height and optimal balance. The perfectly balanced binary tree will look like this:
10
/ \
4 16
/ \ / \
1 5 17 21
(c) To obtain a maximally unbalanced binary tree, the sequence of the same seven items can be rearranged in a specific order. The order is 1, 4, 5, 10, 16, 17, and 21. By inserting them following the defined procedure, the resulting tree will have the maximum possible height and lack balance. The maximally unbalanced binary tree will look like this:
1

Grading criteria Computer organisation and Architecture 1. Explain Linear Tape-Open (LTO), Discuss its advantages and drawbacks List any two current domains where LTO is used. [5 Marks]
LTO (Linear Tape-Open) is a magnetic tape storage technology known for its high capacity, fast data transfer rates, and cost-effectiveness. It is commonly used in domains such as data archiving and the media and entertainment industry. LTO offers a balance between high-capacity storage, cost-effectiveness, and long-term data retention, making it a popular choice in domains that require reliable and scalable storage solutions.
Advantages of LTO:
High capacity: LTO tapes have a large storage capacity, ranging from hundreds of gigabytes to multiple terabytes, allowing organizations to store vast amounts of data in a cost-effective manner.
Fast data transfer rates: LTO drives offer fast data transfer speeds, enabling quick backups and restores. The latest generations of LTO technology provide data transfer rates of several hundred megabytes to over a gigabyte per second.
Long-term data retention: LTO tapes are designed for long-term data storage, with an estimated archival life of up to 30 years. This makes LTO a reliable choice for organizations needing to preserve data for extended periods.
Cost-effective: Compared to other storage technologies like hard disk drives or solid-state drives, LTO tapes offer a lower cost per gigabyte, making it an economical solution for large-scale data storage.
Drawbacks of LTO:
Sequential access: LTO is a sequential access storage medium, meaning data retrieval involves reading the tape sequentially from the beginning. Random access to specific data requires fast-forwarding or rewinding through the tape, resulting in slower access times for individual files.
Fragility: Magnetic tape is susceptible to physical damage, such as stretching, tearing, or exposure to magnetic fields. Mishandling or improper storage conditions can lead to data loss or corruption.
Two current domains where LTO is used:
Data Archiving: LTO is widely used in data archiving domains such as healthcare, finance, and government sectors. These industries generate enormous amounts of data that require long-term retention for compliance, legal, or historical purposes.
Media and Entertainment: The media and entertainment industry relies on LTO for storing and preserving digital media assets, including videos, films, and audio recordings. LTO's large storage capacity and cost-effectiveness make it an ideal choice for managing the vast volumes of media content generated by this industry.

Question 13)In ArangoDB, Secondary indexes are important for speeding up queries. ArangoDB supports four varieties of secondary indexes which are:Geo: This type of secondary index enables searching and sorting by geospatial coordinates. This type of index is used for data that has geographical dimensions.
Examples of geospatial queries include finding all points within a given distance from a reference point, or finding all points within a bounding box.Fulltext: This index type is used to perform full-text searches. Full-text search is a powerful way of searching text by looking for words and phrases that match a given query.
The Fulltext index can search across multiple document fields and it can be used to index a wide range of text data such as documents, blog posts, emails, etc
.Token: Token indexes are useful when you need to find specific documents based on certain keywords. This index type creates an index entry for each word in a document's field that is indexed. Token index is used to speed up searching for specific words or phrases.
TTL: The TTL index is used for document expiration. This type of index enables you to specify a time-to-live value for a document. After the specified time has elapsed, the document will be automatically removed from the collection.
Question 14) In JSON, there are two data structuring concepts: the object and the array. An object is a collection of key-value pairs, where each key is a string and each value can be of any data type. An array is an ordered list of values, where each value can be of any data type.

Two potential input errors that may arise while entering a password of at least 14 alphanumeric characters are: Length of password: The program requires a minimum of 14 alphanumeric characters.
When the user enters a password shorter than the required length, an input error may occur due to the incorrect password length. Data type error: Alphanumeric characters must be included in the password; a user may enter a special character or a character that is not alphanumeric.
The program may reject this as an invalid password input. One of the common issues that arise with a program that calls for the user to input data is the mismatch of data types. For example, when the program requests for an integer and the user enters a string, this leads to a data type error or input error.
Another input error is a range error. For instance, when a program asks for a number between 1 and 100, and the user enters 150.
In addition, error messages and instructions should be clear to the user so that they understand the correct format and range of the data they are expected to input.

Consider an audio CD that contains exactly half an hour of stereo sound. Ignoring any additional requirements for format information and other data to ensure the integrity of the sound samples, calculate the followings:
i. When an audio CD is being played, at what rate do the sound samples appear from the CD?
ii. How many bytes of storage does the CD need to contain?
Assume the sample rate is 44100 samples per second and each sample requires two bytes of storage.
When an audio CD is being played, the sound samples appear at a rate of 44,100 samples per second. Considering a half-hour duration, the CD requires approximately 158,760,000,000 bytes of storage, assuming each sample requires two bytes.
The sample rate of an audio CD refers to the number of sound samples played per second. In this case, the sample rate is 44,100 samples per second, which is a standard for audio CDs. This means that 44,100 audio samples are played back every second.
To calculate the storage required for the CD, we need to consider the duration and the size of each sample. Given that the CD contains half an hour of stereo sound, we multiply the sample rate (44,100) by the duration in seconds (30 minutes × 60 seconds) to get the total number of samples. Multiplying this by the size of each sample (2 bytes) gives us an approximate storage requirement of 158,760,000,000 bytes.

Find an expression for the PSD of an m-sequence PN code when the
chip rate is 10 MHz and there are eight stages in the shift
register. Sketch your result
PN PSD: Expression - PSD(f) = Sum[Dirac(f - k/(N * (1/10 MHz)))]. Sketch - Impulse-like peaks at multiples of 10 MHz.
To find the expression for the power spectral density (PSD) of an m-sequence pseudo-noise (PN) code, we need to consider the properties of the m-sequence and its autocorrelation function.
An m-sequence is a binary sequence generated by a linear feedback shift register (LFSR). It has a length of 2^N - 1, where N is the number of stages in the shift register. In this case, we have eight stages, so the length of the m-sequence is 2^8 - 1 = 255.
The autocorrelation function of an m-sequence is given by:
R(t) = (1/N) * Sum[(-1)^bit(i) * (-1)^bit(i+t)]
where N is the length of the m-sequence, and bit(i) represents the ith bit of the sequence.
The power spectral density of the PN code is the Fourier transform of the autocorrelation function. However, due to the periodic nature of the m-sequence, the PSD is also periodic.
The expression for the PSD can be obtained using the Fourier series representation. For an m-sequence, the PSD consists of impulse-like peaks at multiples of the chip rate, which is 10 MHz in this case.
The location of the peaks can be determined using the formula:
f = k * (1/T)
where f is the frequency, k is an integer representing the harmonic number, and T is the period of the m-sequence.
Since the period of the m-sequence is N * (1/10 MHz), the expression for the PSD of the m-sequence PN code can be written as:
PSD(f) = Sum[Dirac(f - k/(N * (1/10 MHz)))]
where Dirac represents the Dirac delta function.
The sketch of the result will show a series of impulse-like peaks spaced at multiples of 10 MHz, with the highest peak at 10 MHz, followed by lower peaks at 20 MHz, 30 MHz, and so on, up to 255 * 10 MHz, which is the maximum frequency in this case.

Design a PDA ( push down automata) for language :
L= εVA
Pushdown automata (PDA) is a type of automata that can recognize a language that is not possible for a finite state automata to recognize. It is a finite automaton that has an extra memory called a stack. A PDA works in the following way: it reads the input one character at a time and based on the current state of the automata, it performs one of the following actions:
- It moves to a new state.
- It reads a character from the input and pushes it onto the stack.
- It pops a character from the stack.
In this question, we are asked to design a PDA for the language L = εVA, where ε is the empty string, V is a set of variables, and A is a set of terminals. This language can be described as follows: it contains the empty string ε, followed by a variable from V, followed by a terminal from A.
To design a PDA for this language, we can follow these steps:
- Start in the initial state and push a special symbol, say $, onto the stack to mark the bottom of the stack.
- Read the input one character at a time.
- If the input is ε, move to the next state and stay in the same state without reading any character from the input or popping any character from the stack.
- If the input is a variable from V, move to the next state and push it onto the stack.
- If the input is a terminal from A, move to the next state and pop the topmost variable from the stack. If the popped variable matches the input terminal, stay in the same state. Otherwise, reject the input.
- If the input is not in V or A, reject the input.
- After reading the entire input, check if the stack contains only the special symbol $ at the bottom. If it does, accept the input. Otherwise, reject the input.
Here is a formal description of the PDA:
Q = {q0, q1, q2, q3}
Σ = V ∪ A
Γ = Σ ∪ {$}
δ(q0, ε, ε) = (q1, $)
δ(q1, ε, ε) = (q2, ε)
δ(q2, v, ε) = (q2, v$)
δ(q2, a, v) = (q2, ε)
δ(q2, ε, $) = (q3, ε)
where q0 is the initial state, q3 is the final state, and δ is the transition function. The first parameter of δ is the current state, the second parameter is the input, and the third parameter is the topmost symbol on the stack. The output of δ is a new state and a string to be pushed onto the stack, or ε if no string is to be pushed, or ε if the topmost symbol is to be popped.

mAs (milliampere-seconds) is the factor that directly affects the image receptor exposure in radiography. It represents the product of the tube current (measured in milliamperes) and the exposure time (measured in seconds). By adjusting the mAs value, the amount of radiation reaching the image receptor can be controlled. Increasing the mAs results in a higher exposure, leading to a brighter image, while decreasing the mAs reduces the exposure, resulting in a darker image.
kVp (kilovolt peak) affects the overall image contrast, but not the receptor exposure directly. SID (source-to-image distance) affects magnification and geometric distortion but doesn't directly alter exposure. Filtration primarily affects the quality and energy spectrum of the X-ray beam but doesn't directly control exposure. Therefore, the factor of choice to adjust/correct image receptor exposure is mAs.

The incorrect statement about phrase structure grammars is option (C) - In derivations by right linear grammars, only one nonterminal can appear in sentential forms.
Phrase Structure Grammars (PSGs), also known as Context-Free Grammars, are formal systems used to describe the syntax or structure of languages. Let's analyze each statement:
(A) PSG is a 4-tuple that contains nonterminals, alphabets, production rules, and a starting nonterminal.
This statement is correct. A PSG is indeed represented as a 4-tuple, consisting of nonterminals (variables representing syntactic categories), alphabets (terminals representing actual words or tokens), production rules (defining how nonterminals can be rewritten), and a starting nonterminal (the initial symbol from which derivations start).
(B) We apply production rules to rewrite a sentential form into another until we reach a string of terminal symbols.
This statement is correct. In PSGs, production rules are used to rewrite sentential forms by replacing nonterminals with sequences of terminals and/or nonterminals. This process continues until a sentential form is formed entirely of terminal symbols, representing a valid string in the language.
(C) In derivations by right linear grammars, only one nonterminal can appear in sentential forms.
This statement is incorrect. In right linear grammars, also known as right regular grammars, multiple nonterminals can appear in sentential forms. Right linear grammars have production rules where the right-hand side consists of a single terminal or a terminal followed by a nonterminal.
(D) Production rules are a relation from the cartesian product of nonterminals and terminals to the vocabulary of the grammar.
This statement is incorrect. Production rules define the rewriting rules in a PSG. They are a relation from nonterminals to sequences of terminals and/or nonterminals. They specify how to replace a nonterminal with a particular sequence of symbols.
Therefore, the correct answer is option (C) - In derivations by right linear grammars, only one nonterminal can appear in sentential forms.

Given an integer > 1 , the function m() recursively sums
up all the integers
from to 1 . For example m(5) compute 5 + 4 + 3 + 2+ 1 and
return 15 as the result
Here's an example of a recursive function m() in Python that sums up all the integers from a given number down to 1:
python
Copy code
def m(n):
if n == 1:
return 1
else:
return n + m(n-1)
The function m() takes an integer n as input and recursively computes the sum of integers from n down to 1. Here's how it works:
The base case is when n reaches 1. In this case, the function simply returns 1.
For any value of n greater than 1, the function recursively calls itself with n-1 as the argument, and adds n to the result of the recursive call.
The recursion continues until the base case is reached (when n becomes 1), and then the function starts returning the accumulated sum back up the recursion stack.
You can call the m() function with a specific number, like m(5), and it will compute the sum of integers from 5 down to 1, which in this case is 15.

To compute the GINI-gain and information gain using entropy for a decision tree split, we need to have information about the class distribution in each subset resulting from the split. Without specific class distribution information, it is not possible to calculate these measures accurately. However, I can explain the concepts of GINI-gain and information gain using entropy and how they are typically calculated in the context of decision tree splits.
GINI-gain:
The GINI-gain measures the reduction in impurity achieved by a particular split in a decision tree. It is calculated as the difference between the GINI index before and after the split. The GINI index measures the probability of misclassifying a randomly chosen element in a dataset.
The GINI-gain formula is as follows:
GINI-gain = GINI(parent) - (Weighted Average GINI(left_child) + Weighted Average GINI(right_child))
Information Gain using Entropy:
Information gain measures the reduction in entropy achieved by a particular split in a decision tree. Entropy measures the impurity or randomness in a dataset.
The formula for entropy is:
Entropy = -Σ(p * log2(p))
The information gain formula is as follows:
Information Gain = Entropy(parent) - (Weighted Average Entropy(left_child) + Weighted Average Entropy(right_child))

Write a MATLAB function [output] = leapyear (year) to determine if a given year is a leap year. Remember the MATLAB input variable year can be a vector. The output variable too can be vector. Inside the MATLAB function use the length function to determine the length of year. Inside the MATLAB function, use a for-loop to perform the leap-year logical test for each year in the input vector-and store the logical result in the output vector. The output vector should evaluate true (logical 1) or false (logical 0) during the internal for-loop evaluation. Successfully completing the function now allows a user to use vectorization methods to count the number of leap years between a range of years. For example, to evaluate the number of leap years between 1492 and 3097 the MATLAB command sum(leapyear (1492:3097)) is issued - without an external for-loop driving the computation. For the function to be used in the command line, make sure that it appears at the top directory in your MATLAB path. You can find yours by typing the command → matlabpath. Do not adjust the MATLABPATH, just place your . m file in the top directory in the path. Grading: 16 points for leapyear. m,4 points for producing the correct answer in the command line for the number of leap years between 1492 to 3097 using the command, sum(leapyear (1492:3097) ).
MATLAB function leapyear checks if a given year or vector of years is a leap year, allowing vectorization for efficient computation.
The provided MATLAB function, leapyear.m, determines whether a given year or a vector of years is a leap year or not. It utilizes the length function to determine the size of the input vector and employs a for-loop to perform the leap-year logical test for each year in the input vector. The result is stored in the output vector, where true represents a leap year (logical 1) and false represents a non-leap year (logical 0). This function enables users to use vectorization methods, such as the sum function, to count the number of leap years between a range of years without the need for an external for-loop.
The leapyear.m MATLAB function takes a year or a vector of years as input. It first determines the length of the input vector using the length function. This allows the function to handle both single years and vectors of years.
Next, a for-loop is used to iterate over each year in the input vector. Within the loop, a leap-year logical test is performed for each year. The result of the test, either true or false, is stored in the corresponding position of the output vector.
To determine if a year is a leap year, the function checks the following conditions:
The year must be divisible by 4.
If the year is divisible by 100, it must also be divisible by 400.
If both conditions are satisfied, the year is considered a leap year, and the logical result is set to true (1). Otherwise, it is considered a non-leap year, and the logical result is set to false (0).
By using this leapyear.m function, users can easily count the number of leap years between a range of years by applying vectorization methods. For example, the command sum(leapyear(1492:3097)) will return the count of leap years between the years 1492 and 3097. The function facilitates efficient and convenient leap year calculations in MATLAB without the need for explicit looping.
