Sir TCS NQT DRC ki Exam m Mujhe Programming Logic Question Kese aaye..? Mne select to TCS Conginative Skill kiya h🥺..?

[@mohammadumar6340]

I agree that 217 can be the right Child of X so that x range is [94 to 136] [=43 different values] but 217 can also be the left child of X so that x permissible range becomes [218 to 235] [=18 different values] so in total x can have 61 different/unique values

[@thirunmj8263]

Yes....I too rising this doubt .....

[@mdsuhaib.s.a]

Great Buddy

[@bestquotes2765]

Why we shouldn't assume that x value smaller than 93 so that x become left of 93?

[@anandmusicverse6235]

@@bestquotes2765 because the next node traversed from X is 217 and while searching we follow a single path till the searched node . Just try to go for a BST and search any value in it you will get it

[@luciferleviathn]

@@anandmusicverse6235 where would you put 69 or 92 on that tree?

[@sumittripathi632]

in ques 3 there should be specified that the tree is also binary search tree, then only we can perform your procedure other wise information is not enough...... and if this is specified that the tree is binary search tree then we can find post order just after finding inorder as inorder of a BST is just all keys with ascending order arrangement... so at the end we can find post order with the help of pre and in order

[@HyperXD_YT]

ur right

[@seniorhackersgaming8062]

hi

[@reytrance219]

In the last question, the answer will be 61 and not 42 . As - 1) for 93

[@VivekRaj-xv6lf]

Close to answer, we could consider number between 94 to 235 including both and excluding 137 and 217 which turns out to be 235-94+1=142

[@biplabroy1406]

The first explanation of the question was wrong. it's not about 6 zeros there. The actual reason is when we store 0.1 in variable "f" it stored in binary form in memory. we can not convert 0.1 into binary accurately there will be some transaction error. The same question if you do with 0.5 you will get output "yes" without typecasting. Happy coding

[@amruthap6334]

nice

[@icecut7403]

Yes 1st question explanation is wrong

[@AnandKumar-hi6by]

In question 10, i think correct answer would be 43 instead of 42. as x can take values from 94 till 136. to understand this suppose x can be 5,6,7 if we do 7-5 this will give us 2 but here x is actually taking 3 values.

[@sathishkumarnagaraj1897]

@6:52 right to left... Pre increment will have highest priority so 11 + 11 is 22

[@sathishkumarnagaraj1897]

[@RaviRaj-th2dc]

I suggest you, write the entire code in c compiler and execute and check the output.

In the last question answer will be 43 (94 to 136, that's 43 values in total).

you are Right 94 and 136 also include

[@DreamQuestGamer]

Q2. I thought this type of questions solved from right hand side.

[@syedalmastirmizi3477]

answer to ques 10 should be 43 as number of elements between 136 -94 is 43 not 42, Eg: elements between 94-98 is (94,95,96,97,98) =5 (98-94+1=5) therefore 136-94+1 is required

[@kuntalasett3785]

24:28 "Eesha is doing all kinds of things" :p Boss lady!

[@apunbhagwan4473]

esha cn packet question answer should be "queue" as we can implement queue using LL and packets are arriving in an order

[@raunvk]

exactly

[@kiranpoojary493]

answer for Q10 is 43 i.e numbers btw 93 and 137 ( Tn=a+(n-1)*d ) so 137=93+(n-1)1 is 45 then subtract 2(for 93 and 137) from 45=43,like if am right

[@vinamrajha1571]

217 can also become left child of X if X is [218,235] by this X can have 61 possible values

[@Liamlefe]

Sir in Question 7 queue can be the answer because queue is open from both sides just like a pipe for transmission of packets isn't so??

[@HyperXD_YT]

in queue size is fixed

[@raahi431]

I started my prep at 10 pm, have the exam in first slot tomorrow. These are the only videos I can relate to :)

[@vigneshkumarsaminathan1847]

In Qns.10 : As per the sequence of order the X had appeared in-between the number 93 and 217. So, the ans would be 124(217 - 93). In Qns.7 : When we look at the key point "the packets arriving in right order" we can use queue data structure right? as it's increase size based on input.

[@dasmala9255]

I really appreciate your hard work to give easy explanation for students who really need this . I follow Prep Insta 's all video regarding TCS NQT. All the materials are really helpful and I also go through all your website course..Good quality content. 5 stars 🌟🌟🌟🌟🌟

[@kartavyavashist]

In question 7 answer can be queue because FIFO and queue can also be implemented using Linked list.

[@arnavsingh381]

agree, but she wants the recent changes to undo. stack will be good. pop the top

[@ashutoshbisht3580]

@@arnavsingh381 but where she wants recent changes to undo .In telephony audio message you can't undo anything. so,I think queue might be the better answer .

Same here neji, maybe ask sasuke!

[@user-gq1ij]

My answer for question 10 You chose position of x right But after that there will be 2 possibilities 217 will be the right child or the left one If right then 93

[@raunvk]

In Question 7 how can Linked List be the answer when we know in Computer Networking Flow Control Methods like Stop & Wait/Go Back N etc use Queue as the Receiver Buffer to receive data packets from Sender?

[@ashugupta3646]

This video helped a lot, I thought all the important matter would only be in your paid content which I couldn't buy. I hope it all helps in clearing the test.

Thankyou so much for this video today. Much needed video. Tomorrow is the exam. Don't know what type of questions will come

[@PrepInsta]

This video is very important a few questions may also come in the exam !!!

[@nilborban8315]

when you run code for question 2 you get answer 22 as "a" will first pre incremented and will become 11 so a+a = 22 will be assigned to x. Please correct me if i am wrong.

[@saranraj2884]

For the ques 5 Circular doubly linked list the accurate answer

[@Sonu-hg6jm]

sir ques no :2 is giving the ans 22 on turbo compiler which value we take in examination

[@waverache8296]

22 is correct

[@unnathpgowda5437]

Those sort of questions are actually compiler dependent . You can never know what is right answer

[@Venkatalokesh88]

last question (10 q) ans should be 61 not 42....because 93

[@veenusaini1140]

Yes, my answer is also same .I don't understand why they are not considering 217

[@sridattapinna4000]

In question 9, ch is int variable but ch = getchar() is present won't that result a compilation error?

[@tarishitiwari3424]

In last question! What if x value is lesser than 93.. Then it will go to left hand side. So the method will be same for both right and left hand side.!!

[@khairmusic007]

x value can't be lesser than 93 else we will never get to traverse 217 while searching 137, although x can be greater than 217 which isn't mentioned. Reply if I am wrong @Prep Insta

[@nishilama4900]

Sir in first question there's no bracket for "if and else" statement soo no answer ll be printed, the complier ll indicate error...I am saying no answer ll be printed(it ll indicate error)

[@kgame813]

There is no need of brackets for if and else...it still gibes the output

[@nishilama4900]

@kgame , okay 😊

[@anilkumarsivarathri7928]

in last question you need to take 94 &136 so answer is 42+1=43.

[@DeepakKumar-ee6tw]

What if the value of X is 80??

[@sayedrahematullahshakir9924]

In last question, if X is printed on the right of 137 then how it will be less than 137?

[@haranathrakshit]

X ( 94 , 216 ) Possible value of X is (216-94)=122

[@pauldip2388]

1st question, if i put 0.1 it gives "no" but while am putting 0.5 it gives "yes" in actual comliper nut why???

[@kriativt2794]

I think you have missed something in Q3 it should be binary search tree not just tree. If its a normal tree or even binary tree then there is no compulsion on left child should have to be lesser

[@vishalbishtt]

Question 3rd sol. is wrong The order will be 9,11,15,13,19,23,21,17. Because 11 should come before 9 while traversing the tree in post order...the post order format of traversing is left,right ,root and root of left can be 13 and 11 both

[@sabeeharfa9303]

In Q no 10. The value of x can also be less than 68...than why we r not considering that??

[@adityasrivastava6235]

if we start our search from 68, how come x would be less than 68

[@csebmanaseenitinvaidya8223]

In que 10 I have a doubt. The value x is on left side of 93. So it must be less than 93 and greater than 68. Then how the answer was calculated ???

My Answer is 147 216-69=147

X won't be on left side of 93. Go study bst traversal first
