sure? If I make a pause of 400ms [ usleep(400) in PHP ] the test goes right, but if I pause for 500ms the test fails in "Large dataset (300 pts)". So I assume this is the checking for slow program.
"limit size in filenames" have no sense about program velocity check.
Please, any ideas on the "limit size in filenames" check?
The problem was the original input line suggested by the platform:
$FNAME = stream_get_line(STDIN, 256, "\n");
the problem disappeared using this one:
$FNAME = stream_get_line(STDIN, 2560, "\n");
