In set A,

Little endian question answer given as c ,where as it should be B.

And disk capacity problem answer is given as 1250 where as it should be 1280. Is it same with other sets also??

---

@Susheel It will be 1250 only,because when you convert it into KB you will have to divide by 1024 instead of 1000.

---

I guess the answer to this will be software pipelining and not loop unrolling. ( source:  wikipedia).

---

@bhaskar_33 ceil will take the upper limit while the floor will take the lower limit value. For finding the height floor would be the answer.

For n=13 height comes out to be 3 and its the floor value.

---

Questions having two correct answers should definitely be excluded from marking because ISRO has not explicitly stated anywhere about this rule. Why would anyone take the risk of getting negative mark ?

What is the rule of these type of questions in GATE exam?

---

I completely agree with you please raise this question

---

Answer related to tree edge after BFS traversal will have multiple options as its answers. Please refer the below link for justification.

Here and means either of option you marked it is correct

---

But what about them who did not mark any answer because of ambiguity in answers.

---

Getting 111 marks. If big endian option changes it will become 115. Any chances of shortlisting

---

For the postorder to preorder conversion, please refer to the link for justification.

https://gateoverflow.in/331364/isro2020-36 , should be c (O(n)) , but they make it not evaluated.

---

Is official answer key out ??

---

@ben10 There are two questions in it, as per time complexity its B, as per invalid string ( its ambiguous, assuming its meaning is invalid time complexity) its C. That is why its excluded.

---

absolutely right

---

There is no point of any debate/discourse here. Answers that you feel should be challenged, just challenge them when the link becomes available. If ISRO accepts them, well and good. If it doesn't, there is not much anyone can do about it. Anyway, cut-off would, by no means, go below 130. I know some guys in made easy claiming to score as high as 160+ .

---

everyone will be surprised seeing the cutoff this time. Just wait for it & prepare for gate meanwhile.

---

I am getting 151 marks excluding question not considering for evaluation. what are my chances for the selection for interview.

---

100 percent
