Query for Mock Question 2-4 (doCounting)

[Adnan Jamil]

What do we mean by P and Q as False. Why did we set it as False and what does it mean in the pseudocode. 

Please help me with the logic of setting 

P= False, Q=False

thank  you

[Krishna G]

We are initialization a variable P and Q as false, ( Similar to count = 0 ) now we we read the code, line 6 If (x.part of speech == "Pronoun" and Q 

Means the word should be pronoun and False, so the First pronoun word will become false so it wont count, it will continue to line 7 and in line 18 we are making Q = True, so it will calculate all the pronoun expect the first one.

Regards,

Krishna.G

Hi Krishna, 

Thank you for your response and the explanation. 

Can you please help me with the lecture out of 4 weeks study material in which we were taught to initialize variable as Boolean 

Eg A=True, B=False etc. 

I will really appreciate it.

Hey can you please explain how c value was calculated

I used the same approach to calculate C and also there was a question replacing and with Or, in that case it will calculate the first one.

Adnan

Good question but In my opinion AND is a Boolean operation also what I feel about true, false that they have stated is the result or the outcome, anyway I will check one more time.

BTW, how was the stats test, I found it much tougher than covid.

[811_BaEco_Eve_5 Sxc]

The stats paper was soo lengthy and very differently from all the assignment we have done.for finding the value of c what did if (P)mean as P was just written false pls help

[DHARMA TEJA GODUMALA]

IF (True) then only you will enter into that if loop

If (False) you will skip that if loop.

[Lokesh Jadhav]

thank you, your explanation is really helpful,  Would you like to explain Q.6 how line 10 is wrong. please help

[Malabika Guha Mustafi]

The condition was to check sum of the subject difference  whether equal to total difference. Definitely, the expression was not right to check the condition .

Hi 

Please excuse my query:

Doesn't below code mean that B will get incremented ONLY WHEN the condition Q=TRUE (AND when the word is a Pronoun)?

Can anyone kindly confirm this?

Thanks in advance.

Best Regards,

Anirban

[Malabika Guha Mustafi]

Yes. 

[Malabika Guha Mustafi]

@Ac In line 18, Q is assigned as True. So B will take all pronouns' counting except first one for each sentence{ since during end word counting again Q is assigned as False in line  21).

[AC]

OK, then in Q: 5:

"If the and operator in Line 6 is replaced by the or operator, then what will the value of B represent at the end of the procedure?"

then B will get incremented irrespective of the fact if Q is true or false, as long as the word = Pronoun?

That is, B will now calculate the letter-count of ALL pronouns, including the first one for each sentence, right?

i.e  if the sentence begins with a Pronoun, then letter-count that too will get counted in B; as opposed to the previous case, is that correct?

Thanks in advance.

Best.

[Malabika Guha Mustafi]

Yes, All pronouns and all other words also but excluding the beging word if it is not pronoun.[ Then both the or operation is false].

[AC]

Thanks a ton for the clarification!

So if I understood you correctly then the next bit of code:

means that C will only be incremented IFF the word on the card is a Noun AND that P =TRUE, right?

Best.

[Malabika Guha Mustafi]

Yes, but it is calculating only consecutive nouns excluding the first word( since, first P=false but if it is noun then without incrementing it will take P= true from line 13) .

next word if it is noun (consecutive ) then increment C but if it is not then p=false (from line 16)

[AC]

Great!👍

Then if I have 2 sentences like: "Joe Biden Junior has ousted Donald Trump. Hunter Biden is Joe's son" - in that order and feed it to this part of the code:

In such a case: C will contain letter-counts for "Biden, Junior" and "Trump,Hunter, Biden" and "son". Is that it?

Notice, the lettercount ran over a full stop (.)  in the "Trump,Hunter, Biden"  case as the last word of the 1st sentence and the 1st word word of the 2nd sentence (being consecutive nouns) ought to get counted in C variable, right?

Best.

[Malabika Guha Mustafi]

Yes, since P is not affected by fullstops then it'll be executed as per your assumption.

[Srinath Sai]

Is the extension of the Q loop as highlighted in yellow colour below from Line 6 to Line 17?

So, at Line 6, since Q's initial value is False, it doesn't enter this yellow-coloured loop at all, and just directly jumps to Line 18 where Q's value will be changed to "True"  and it continues thereafter for the subsequent cards. Am I right? 

1    Procedure doCounting

 2 A=0, B=0; C=0

3      P = False, Q = False

4       while (Table 1 has more rows) {

5       Read the first row X in Table 1

6       If (X.PartOfSpeech == "Pronoun" and Q) {

7       B = B+X.LetterCount

8       }

9       If (X.PartOfSpeech == "Noun") {

10     if (P) {

11     C = C+X.LetterCount

12     }

13     P = True

14     }

15     else {

16     P = False

17     }

18     Q = True

19     if (X. Word ends with a full stop) {

20     A = A+X.LetterCount

21     Q = False

22     }

23     Move X to Table 2

24     }

25     return ([A, B, C])

26 End doCounting

 

 

[Malabika Guha Mustafi]

No..

[Malabika Guha Mustafi]

First if loop starts at 6 and ends at 8. Second if is not nested within first.

Anyhow since P and Q   are false at first so for initial word both if loop will not counted.

Thank you!

[gorthi lakshmisahitya]

Hi guys 

I am Sahitya . My doubts were also the same as stated above.

Hence, the above conversation has helped me to understand the code.

Thank You!

[Sree Kavitha]

im a biology tudent , i really cant understand even ur discussions, pl help frnds

[DHARMA TEJA GODUMALA]

Sorry a small correction from my side

In the above If is Not a loop ,

I frequently mentioned it as loop which is wrong,

if is a condition statement please correct my wording mentioned above. Remaining is fine.

@krish can you please explain this concept using an example

thank you

[Malabika Guha Mustafi]

@ Sree,

Many people like me have non IT background. The syllabus is only covered very basic things.

Don't worry, you can easily pass the exam if some basics are clear.

1. Whenever there is a if condition, first check the braces. Where it is started and where it is ended. It will give you clear idea that which activities are under the if or condition.

That means, if the conditions stated are true then the activities within the braces will  be executed otherwise NO.

2. Check the condition itself.

It may be single ( like parts of speech == noun) 
Or multiple ( like  parts of speech== pronoun and P, where p is a variable)

If it is multiple then check the logic operator ( the operation is AND or OR between the conditions).

 If it is AND then all the conditions should be true(individually).[ for example, parts of speech== pronoun and P here both the conditions should be true  to execute the loop].

If it is OR  then if any one of the condition is true , then the if statement will be executed. ( it may be happend that all conditions or more than one condition are true).

Maximum questions are covered this part only, Hope, it helps you. All the best.
