### Re: 11504 - Dominos

My simple C++ implementation of Kosaraju's algorithm runs in 0.7 sec, so yours is probably slower because of language. What language do you use?

EDIT: oh, I see you code in C++. So it might be because of cin/cout instead of scanf/printf.

Thanks you all, I got AC, but only after setting precision of V to 1e-10 (1e-8 didn't work).

### Re: 10767 - Barcelona's trams

I used dynamic programming to find the best velocity for the x-th segment if I arrive with y crashes. When computing this, the corresponding function T(v) (input: speed on the x-th segment, output: expected time to finish the whole track, valid inputs: (0,M-y> ) has only one local minimum and this ...
