yup. same for me. How many did you solve?
i am also getting the same
1 problem, u?
I did both.
Did u got special permutations question?
yes showing not participated
Where an array consists permutation of n numbers and has to be split into two arrays such that the difference of their sums is minimum?
I also solved both coding questions, not sure about all MCQ’s though
i have solved both coding , and mcqs are also correct all . can i get a call ?
The chances are slim but hope for the best.
paper was really easy .many have solved fully . surely they will make some other criteria to shortlist
yes I got that and other was on string.
No. Thats not the case with everyone. There are insanely hard problems like : Prime Rangers/Unique Paths which are too hard to be done in 2 hours time for even a good coder. Many people had these 2 problems in their sets as well.
Yes, there are equal number of people who got both questions as easy like : Shops&Candies,Minimum difference,Chocolates,robots,Areas,maximum-queue problems,stones&safes. These problems were 10 times easier.
Also, one problem : Minimum sum was a wrong problem asked in NCR test,bad luck for those, whose set had it.
where to check for NCR result?
Are the results declared?
Prime rangers solution? I got partial
I solved it after the contest. Applied digit-dp and heavy combinatorics, my code is lengthy . Will add its link in morning.
Basic idea: Calculate count of numbers who have more 2s then 3s,but have more 3s than 5s,but have more 5s than 7s.
Minimum Sum was not a wrong question. It was correct and i solved it completely. Also the announcement page displayed that not participation thing way before the contest. That page is not legit.
Hey, there . I need to verify something . This was the problem statement of minimum sum :
Construct a tree of “N” nodes. Each node should have a distinct value. 2 nodes x and y , have can have an edge between them if (x&y) > 0 , for N=4, the sample test had the output : 10.
Cost of adding edge between x and y is : (Total number of set bits in x and y)
But a better tree of cost 9 can be constructed with edges :
1—2(Cost=3)
2—3(Cost=3)
1----4(Cost=3)
Where, a[1]=1 , a[2]= 3, a[3]=2,a[4]=5
Please explain me , instead of 9, why their sample output says 10 ? , which is surely wrong(according to me), please explain , how did you find it correct and also the solution. I will be more than grateful .
