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 sstudent ids (numbered from 0 to k-1) of students who registered for session i.
