No, I do not think that the cut-off will be full marks.110-140 seems good, although the problems were not that difficult.
I hope I get selected.
And no, int won’t exceed, as x,y coordinates were between 0-10^5 range.
Also no chances of stack overflow with recursive DFS?
Actually I did the first in one hour and the second using top down in one hour. The last hour was spent doing bottom up which was giving SEG FAULT because I initialized the array on the stack. So I didn’t check the first that properly.
I also did the second problem using top-down.That should not give stack overflow. However, in the second problem, I really do not know as in Java at least, it would have given so.I do not know the stack size in C++, but Java, it is less than 10^4.And I never tried recursive dfs, because I always do the iterative one and it has become kind of a habbit in graph algorithms.Still , hope for the best.
Are you seriously asking this? o.O

@sampritipanda The solution for 50 points (when you store the strength explicitly) is very similar to knapsack DP. Converting it to 100 is just an easy observation 
Maybe TL for problem 2 subtask 1 was somewhat weak. My code that was getting accepted actually took around 2.4-2.5 seconds offline on max test(randomly generated). That or the PCs provided were much slower than codechef.
@nibnalin, TLs were pretty generous. We did not want to force people into making constant optimizations. This isn’t long challenge xD

How much did you score?
Are the codes that we actually submitted going to be reevaluated or the ones that we had to store in the desktop.If it is the latter case, I think I may have left the public before class declaration, which is not allowed in codechef.Eclipse generates public classes by default, so when I submit, I explicitly remove it.But when I saved It , there is a small chance that I may have forgotten to remove it, although the rest of the code is same.Although I think I have removed it, please check it nonetheless once before reevaluation, if that code is going to be checked.roll number is zco31038.
I can see only abt 15
When will be the results out?
The personal results have been mailed. Regarding official announcement, you may have to wait for a week or so I guess.
Is it like that those who have qualified have only got email?
No, i didn’t qualify but I got an email.
sorry , a late reply, wont the answer be 2*(number of elements +1) always ? As no matter how is the orientation, number of faces is justified by above formula ? I tried it on paper.
