1.reverse is a recursive procedure to reverse a list. Select the correct code fragment to complete the pseudocode given below. It is a Multiple Select Question (MSQ).

 
 
 
 
Procedure reverse(L)
    if(length(L) <= 1){
        return(L)
    }
     *********************
      * Fill the code *

End reverse
 

return([last(L)] ++ reverse(init(L)))

return([first(L)] ++ reverse(rest(L)))

return([last(L)] ++ reverse(init(rest(L))) ++ [first(L)])

return([last(L)] ++ reverse(rest(init(L))) ++ [first(L)])

Question:2-4:

An auto-grading system for an online course is designed in the following way:

∙

A student’s submission is recorded as a dictionary with the following keys

\circ

The “roll” key maps to the student’s roll number.

\circ

The “time” key maps to the time of submission

\circ

The “score” key maps to the student’s score for that submission

∙

Each student can make multiple submissions before the deadline.

∙

Every time a student makes a submission, the dictionary corresponding to it is appended to the end of a list called scores.

An example:

 
scores =   [{“roll”: 12, “time”: 10:20, “score”: 80 },
            {“roll”: 20, “time”: 11:23, “score”: 70 },
            {“roll”: 12, “time”: 20:40, “score”: 90 },
            {“roll”: 12, “time”: 23:50, “score”: 95 },
            {“roll”: 20, “time”: 23:53, “score”: 65 }]

Study the following pseudocode:

 
Procedure isPresent(L, roll)
    foreach D in L{
        if(D[“roll”] == roll){
            return(True)
        }
    }
    return(False)
End isPresent

 
 
 
 
 
Procedure getSubs(L)
    firstSub = {}, restSub = []
    if(length(L) <= 1){
        return(L)
    }
    firstSub = first(L)
    restSub = rest(L)
    if(isPresent(restSub, firstSub[“roll”])){
        return(getSubs(restSub))
    }
    else {
        return([firstSub] ++ getSubs(restSub))
    }
End getSubs
 

Answer questions 2 to 4 after executing the pseudocode given below:

 
submisssions = []
  
scores = [ {“roll”: 12, “time”: 10:20, “score”: 80 },
           {“roll”: 20, “time”: 11:23, “score”: 70 },
           {“roll”: 12, “time”: 20:40, “score”: 90 },
           {“roll”: 12, “time”: 23:50, “score”: 95 },
           {“roll”: 20, “time”: 23:53, “score”: 65 } ]
    
submisssions = getSubs(scores)

2. What is the value of submissions?

[ {“roll”: 12, “time”: 10:20, “score”: 80 },

{“roll”: 20, “time”: 11:23, “score”: 70 } ]

[ {“roll”: 20, “time”: 11:23, “score”: 70 },

{“roll”: 12, “time”: 10:20, “score”: 80 } ]

[ {“roll”: 12, “time”: 23:50, “score”: 95 },

{“roll”: 20, “time”: 23:53, “score”: 65 } ]

[ {“roll”: 20, “time”: 23:53, “score”: 65 },

{“roll”: 12, “time”: 23:50, “score”: 95 } ]

4 points

3.What does the variable submissions represent?

The list of all the submissions made by the students sorted in the ascending order of time.

The list of all the submissions made by the students sorted in the descending order of time.

The list of the last submissions made by the students sorted in the ascending order of time.

The list of the last submissions made by the students sorted in the descending order of time.

The list of the first submissions made by the students sorted in the ascending order of time.

The list of the first submissions made by the students sorted in the descending order of time.

4 points

4.Assume that reverse is a procedure that reverses a list. Which of the following statements returns the list of the first submissions made by the students sorted in the ascending order of time?

getSubs(scores)

reverse(getSubs(scores))

getSubs(reverse(scores)))

reverse(getSubs(reverse(scores)))

5.outcomes is a list of strings that contains the information about the outcome of cricket matches played by India in a tournament. Assume that each element in the list is either “win” or “loss”. For example, if five matches have been played, then outcomes could look like this:

[“won”, “lost”, “lost”, “won”, “won”]

We call a list of outcomes a blank slate if the number of wins is equal to the number of losses. blankSlate is a procedure that accepts outcomes as input and returns True if it is a blank slate and False otherwise. Select the correct code fragment to complete the following pseudocode. It is a Multiple Select Question (MSQ).

 
 
 
 
Procedure blankSlate(outcomes)

QUESTION-6-7

2n chess players are participating in a tournament. Each player is given a unique participant ID that is represented as a string. The player IDs are stored in a non-empty list players in the descending order of their rating, i.e., the first element in the list has the ID of the player with the highest rating.

The matches are scheduled as follows: The $i^{t h}$ match is between the $i^{t h}$ player from the top and the $i^{t h}$ player from the bottom of the rating list. We wish to create a list called matches which stores the sequences of matches, starting with the first match and ending with the last match. Each match is represented as a list of two players, the first element of which is the ID of the player with the higher rating, while the second element is the ID of the player with lower rating. Assume that no two players have the same rating.

Answer questions 6 and 7 based on this information.
