diff program output N = 1 with this output file to check your program is correct before contributing.
Each program should print "hello world" and exit.
This benchmark measures startup costs. It is run differently than the others - each program is run N times in a loop by a shell script wrapper. We show the mean CPU time. Most hello world programs are too fast for the way we measure memory usage so we only show CPU time.
