Um horário possui o formato `hours:minutes`. Ambas as horas e os minutos possuem dois dígitos, como `09:00`. | ||

Make a regexp to find time in the string: `subject:Breakfast at 09:00 in the room 123:456.` | ||
Componha uma regex que encontra o horário na string: `subject:Café da manhã as 09:00 no quarto 123:456.` | ||
|
||
P.S. In this task there's no need to check time correctness yet, so `25:99` can also be a valid result. | ||
P.S. Nessa tarefa não é necessário verificar a corretude do horário ainda, então `25:99` também pode ser um resultado válido. | ||
