Results of a competition for the fastest program that sorts a large file

Each program submitted by a student was tested on three files of different sizes: 120KB, 1.5MB and 31.5MB. The table contains running times in seconds on these files from the smallest time to the largest, omitting results for programs that crashed or run seemingly too long. Due to privacy concerns, identity of participants is not revealed. The fastest program on a file is not necessarily the fastest program on a different file.
