## Trace Data File Format

The trace data is stored as a text file containing a series of integers.

The first line in the text file consists of two integers.
The first integer gives the total number of sessions *n*, and the second
integer gives the total number of students *k*.

The subsequent *2n* lines give information about sessions, sorted by the
start time of sessions. Each session
is described in two lines. The first line gives four integers, giving
the start time of a session (in business hours, starting
from hour 0), the session id *i* (numbered from 0 to *n*-1), the number of
students in the session *s*, and the duration (in hours). The next
line lists *s*student ids (numbered from 0 to *k*-1) of students
who registered for session *i*.
