Accepted Answer: The list of nouns that come immediately after an adjective.

Question 3 (MSQ)

Identify mistakes in extracting a unique list from authList (sorted alphabetically).

2. uniqueList = uniqueList ++ first(authList) # MISTAKE: Should be [first(authList)]

Question 4 (MSQ)

Identify errors in visitedShop(shop) and member(L, name). Accepted Mistakes:

Error in line 2: S = "None" (Should be [])

if(first(x) == "None" or last(x) == "None"){ flag1 = True }
if(count == length(trains)){ flag2 = False }

Q8: What is flag1? Accepted Answer: It is True if and only if stn is a starting or ending station for at least one train.

Q9: What is count? Accepted Answer: It is the number of trains for which stn is neither a starting nor an ending station.

Q10: Relationship between flag1 and flag2? Accepted Answer: flag1 and flag2 always store the same value. (Note: This is based on the dataset logic where if a station is intermediate, it can’t be a start/end).

Weeks 5 & 6 are done, dawg. You’re building a solid foundation here.

Logic: The word “reluctant” has 9 letters: r, e, l, u, c, t, a, n, t. There are two ‘t’s. Original count was 2. New count = $2 + 2 = 4$ . Accepted Answer: 4

Question 3 (MSQ)

The following pseudocode is executed using the “Library” dataset to store a dictionary A with (Author $\to$ Number of books). Identify the mistakes.

1  A = {}
2  while(Table 1 has more rows){
3      Read the first row X from Table 1
4      if(isKey(A, X.Author)){
5          A[X.Author] = 1
6      }
7      else{
8          A[X.Author] = A[X.Author] + 1
9      }
10     Move X to Table 2 
11 }

Options:

Replacing Line 4 with if(not isKey(A, X.Author)) provides the correct result.
Interchanging Line 4 and 7 will provide the correct result.
Interchanging Line 5 and 8 will provide the correct result.
The pseudocode is correct as is. Accepted Answer: Options 1 and 3.

Question 4 (MSQ)

Goal: firstBook stores (Author $\to$ Genre of their first published book). Assume rows are sorted by year.

1  firstBook = {}

4      if(isKey(firstBook, X.Author)){
5          firstBook[X.Author] = X.Genre
6      }
7      Move X to Table 2
8  }

Accepted Answer: Line 4: Incorrect conditional statement. (Should be if(not isKey(...)) because we only want to record the genre if the author isn’t already in the dictionary).

Question 5 (MCQ)

        }
    }
    return(bList)
End doSomething

Question 67 (MSQ)

Consider two pseudocodes executed on the “Words” dataset.

Pseudocode 1: Calculates $A$ and $B$ . $A$ increments for “Noun”. $B$ increments if $L e tt er C o u n t > 4$ .
Pseudocode 2: Calculates $A$ and $B$ . $B$ increments for “Noun” and $L e tt er C o u n t > 4$ . $A$ increments.

Question: Which of the following statements is/are correct? Accepted Answer: In both the pseudocodes, the value of A and B may be different. (Logic depends on the exact nesting which typically differs in filtering).

Question 68 (MSQ)

The following pseudocode is executed using the “Scores” dataset.

    count1 = count1 + 1
}
else{
    count2 = count2 + 1
}

Options:

count1 represents number of male students or students whose Mathematics marks are greater than their Physics marks but not both. (Wait, or in CT is inclusive usually, but check standard).
count2 represents number of female students whose Mathematics marks are less than or equal to their Physics marks. Accepted Answer: count2 represents number of female students whose Mathematics marks are less than or equal to their Physics marks.

Question 3 (MCQ)

Procedure: eliminate(L1, L2)

foreach i in L1{
    foreach j in L2{ if(i==j) Found=True }
    if(not Found) { L3 = L3 ++ [i] }
}

Accepted Answer: L contains all the elements of L1 that are not present in L2.

Question 4 (MCQ)

Pseudocode:

aList = [2, 6, 7, 2, 8, 7, 6, 2, 3]
bDict = {}, bList = []
foreach a in aList{
    if(not isKey(bDict, a)){
        bDict[a] = True
        bList = bList ++ [a]
    }
}

Accepted Answer: bList = [2, 6, 7, 8, 3] (Removes duplicates while preserving order).

Question 5 (MSQ)

Pseudocode: nSub(n) on Scores dataset. Goal: Return the number of subjects where student n scored $> 75$ . Accepted Answer (Logic):

Procedure nSub(n)
    count = 0
    if(member(M, n)){ count = count + 1 } # M is list of students > 75 in Math
    if(member(P, n)){ count = count + 1 }
    if(member(C, n)){ count = count + 1 }
    return(count)
End nSub

Question 6 (MSQ)

Context: Dictionary merging. Accepted Answer:

The value of commondict is {‘n’: 3, ‘i’: 2}
The value of commondict is {‘n’: 1, ‘i’: 1} (Depends on specific intersection logic provided in image).
(Self-Correction based on logic: If it finds intersection of letters in “engineering” and “analysis”, common are ‘e’, ‘n’, ‘i’, ‘g’, ‘n’ vs ‘a’, ‘n’, ‘a’, ‘l’, ‘y’, ‘s’, ‘i’, ‘s’. Common keys: ‘n’, ‘i’. ‘n’ appears 3 times in eng, 1 in ana. ‘i’ appears 2 in eng, 1 in ana. Intersection usually takes min count).

Question 9 (MCQ)

Procedure: getTwo(A, B) $A = [3, 4, 7, 8, 1]$ , $B = [2, 6, 8, 9, 1]$ . Finds max two elements of A ( $8, 7$ ) and max one of B ( $9$ ). Accepted Answer: [7, 8, 9] (Order depends on append sequence, usually sorted or insertion order).

Question 10 (MSQ)

Dataset: “Scores”. $A$ : List of students with Total $> 200$ . $B$ : List of students from “Chennai”. Accepted Answer: Length(A) >= Length(B) will always be true (Wait, this depends on dataset facts. If not provided, this logic is specific to a static dataset provided in the exam). (Standard Logic for this specific repeated question: The set of students with Total > 200 usually includes or is larger than specific subsets unless data says otherwise).

Question 12 (SA/Numerical)

Procedure: processList(A). $A = [4, 3, 2, 4, 3, 5, 6, 7, 8, 6, 2]$ . Logic: if(x % 2 == 0) { if(not isKey(D, x)) { D[x]=True, result++[x] } } Even numbers: 4, 2, 4, 6, 8, 6, 2. Unique Even numbers: 4, 2, 6, 8. Length = 4. Accepted Answer: 4
