Add here if more questions are to be reported Shubhgupta commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213564/isro2018-24 : D) should be correct. dark.hacker.beyhadh commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213587/isro2018-1 ,we will get a compilation error because 'char' is extra. dark.hacker.beyhadh commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213564/isro2018-24 L(A*B)∩∩ B gives the set B. SO OPTION c is also false. Answer should be D) dark.hacker.beyhadh commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213545/isro2018-43 Run on Compiler. It results in compilation error ..Reason is there is invalid initialization of non-const reference of type 'int&' from an rvalue of type 'int' in the line q+=b(a(q)); .So correct answer should be a).. pream sagar commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213545/isro2018-43 ans should be A but given ans is D dark.hacker.beyhadh commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213508/isro2018-80 In B) Solve it completely. Both postorder and inroder are not same. So answer should be none of these. shahidhope commented Apr 25, 2018 Like reply Follow Share Yes this question is in correct. shahidhope commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213515/isro2018-73?show=213908 shahidhope commented Apr 25, 2018 Like reply Follow Share https://gateoverflow.in/213515/isro2018-73?show=213908 is this correct in key.

According to key, the answer is option D: "None of the above". Tuhin Dutta commented Apr 26, 2018 Like reply Follow Share Yes D) is correct. The answer is n + 3m + 30. We need to consider Kilo in $2^mKB$ Aman Juyal commented Apr 26, 2018 Like reply Follow Share Sorry it is for 73 question which was asked earlier .May be I have replied to wrong person vashisht commented Apr 26, 2018 Like reply Follow Share https://gateoverflow.in/213551/isro2018-37 question 37 answer should be d Aman Juyal commented Apr 26, 2018 Like reply Follow Share After analysis ,may be Isro is considering like this let say t(1)=t(2)=t(3)=K ( here K is constant); now t(4)=t(3)+t(2)-t(1) ---> t(4)=t(3)=K; similarly t(5)=t(4)=K |*- t(n)=t(n-1)=k; at the end time complexity would come out to be O(k) i-e constant if I am wrong rectify me. vinz pandey commented Apr 26, 2018 Like reply Follow Share If this analysis is correct, wouldn't option C) T(1) - T(3) = T(2) be correct too? accordingly -> T(2)+T(3)=K, T(1)=K T(4)=T(3)+T(2)-T(1) = 0 T(5)=T(4)+T(3)-T(2) = 0 and time complexity will be independent of data ie constant. Aman Juyal commented Apr 26, 2018 Like reply Follow Share t(3)+t(2)=t(1)=k; t(4)=0; t(5)=t(4)+t(3)-t(2)--->t(5)=0+k-t(2)--->t(5)+t(2)=K (1) eqn; t(6)=t(5)+t(4)-t(3)---->t(6)=k-t(2)+0-k+t(2)=0; t(7)=t(6)+t(5)-t(4)-->t(5)=K-t(2) now if this gonna be sequence so t(5)+t(7)=2K-2t(2)---->t(5)+t(7)=2(k-t(2)) assume k-t(2)= k' again a constant so t(5)+t(7)=2k' |*-t(n)+t(n-2)+t(n-4)------t(5)~nk . ultimately i want to say (t(5)=t(4)+t(3)-t(2))!=(t(5)=0) rectify me if i am doing wrong. what you think now vinz pandey commented Apr 26, 2018 Like reply Follow Share yep. Found my mistake. thanks Dumbest Kid commented Apr 26, 2018 Like reply Follow Share 70 (A paper) should be (d) right? Ran the program and giving like 2000 count.

If P is guaranteed to terminate which of the following statements must be true? 1) P has a local variable 2) P has a execution path where it does not call itself 3) P either refers to a global variable or that has atleast one parameter. In key it given as both 2) and 3) are correct. But only statement 2) is correct. Consider a procedure refers a global variable or has atleast one parameter. But if it is not using that variable in its base condition then also the procedure doesn't terminate. It terminate only if termination condition properly use these variables. We can easily find an example. Please comment.. mystylecse commented May 4, 2018 Like reply Follow Share Same thought yaar, pls chalange that question.
