Why unrated for div-1 :( ?
Because we were unable to come up with enough good problems for a rated div 1 contest :(
Hopefully, next time, cheers!
Yeah, It's hard to create problems challenging enough for top div1 participants.
Nevertheless prizes are open for all :)
And though it might be unrated for you, but you still stand a chance to win cool cash rewards!!
Sure thanks for replying :)
You are most welcome bro :)
Why no seperate ranklist for Div1?
Please make a separate ranklist for Div1 participants.
There will be a separate ranklist for Div1 participants.

As a tester, I want certificate and a letter of recommendation. xD

Will an editorial be posted?

Geothermal orz!!
Interesting problems! Thanks for the contest.
Nice contest, really liked CYBTREE but I feel tests of "Rise of Cyborg" were weak, my solution would fail in tests where there would be more that one occurrence of the minimum element in a range, I just submitted after seeing the high accuracy rate on that problem.
Mind blowing contest. Good job setters :)
Thanks :)

I solved the first four questions today. I had a correct divide and conquer with RMQ via sqrt-decomposition approach for the fifth (now AC), but I messed up some details in the code. YT livesolve/editorial link
