Ok!

By the way can it manage n= 10^6?

Thanks dude!

Thanks

Fortunate to have such a helpful community!

Thanks a ton!

Yes indeed.This problem can be solved using sqrt decomposition.

I think in the tutorial to Problem 907A — Masha and Bears, the point 4-->(Masha likes last car, so it's size is not more than 2·V3) must be (Masha likes last car, so it's size is not more than 2·Vm) . @veschii_nevstrui

I think it's given in the question that a tank in cell n can move to only cell n-1 except for 1 wherein it moves to 2

For problem C what if i throw bombs on all cells starting from last to first and then again in the 2nd cell.It gives n+1 as my answer.

Is it 13th of October or November?
