    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 :)

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.

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
