Write a logic-based algorithm that determines the required number of buses for this schedule and lists the feasible chain of trips for each bus.

Convert the algorithm into python code if possible.

\begin{tabular}{lllll} Route & Trip & Departure & Arrival \\ \hline 1 & 1 & 8AM & 8:35AM \\ 1 & 2 & 8:30AM & 9:05AM \\ 1 & 3 & 9AM & 9:35AM \\ 1 & 4 & 9:30AM & 10:05AM \\ 1 & 5 & 10AM & 10:35AM \\ 1 & 6 & 10:30AM & 11:05AM \end{tabular} \begin{tabular}{lllll} Route & Trip & Departure & Arrival \\ \hline 1 & 1 & 8AM & 8:35AM \\ 1 & 2 & 8:30AM & 9:05AM \\ 1 & 3 & 9AM & 9:35AM \\ 1 & 4 & 9:30AM & 10:05AM \\ 1 & 5 & 10AM & 10:35AM \\ 1 & 6 & 10:30AM & 11:05AM \end{tabular}
