A cinema hall has equidistant rows `1 m` apart. The length of the cinema hall is `287 m` and it has `287` rows. From one side of the cinema hall, laughing gas `(N_(2)O)` is released and from the other side, weeping gas `(C_(6)H_(5)COCH_(2)Cl)` is released. In which rows, spectors will be laughing and weeping simultaneously?
